    ๐Ÿ“ HARTLEY FLARELINE, DAY ON THE RIVER.

    View All
    A few screen grabs from 2 cameras from Saturdays attempt at a launch and retrieval video in the Waiwera River a few creeks north of my place. A number of things didn't quite go according to plan (trying to use 2 cameras, driving a boat and a vehicle using 2 TXs all at once by myself,- a bit like a one armed paper hanger๐Ÿ˜) Got a couple of vids, but the main one is in QT MOV which I don't have an editor for yet, so I'll do that later. Nice day out despite the problems. Big sea fog till about 11am, and still a bit hazy during the day.

    As you can see, the new camera is quite an improvement on the older one.
    As I was using the boat ramp, I had to contend with the 100% boats a few times. Luckily it's quite secluded and not too busy. Funny bringing a model home and having to treat it like a full sized boat,- flushing it out and washing it ๐Ÿ˜

    Hi Trev, stuffed the video up a little bit, as I had made a bracket up to mount the camera on the TX, and I hadn't noticed that it tilted down a bit (notice pic 2) and I missed a bit here and there. Also forgot a few times to turn my body to follow the boat (used to having the camera on my noggin) so I got a few patches of nothing. Fun trying all the same

    Hopefully will be better next time, and thinking of Using the Amphitruck (bigger, heavier and 4x4 rear ) to try a launch next time, as the ramp was wet and the jeep was loosing traction, (a lot to ask for it to pull a total of 13lbs up a wet steep rough ramp๐Ÿ˜ It would do it in the dry ok, as I've previously slope tested it at home.

    You wouldn't believe it, but the next day was total 'carp'- rained all day, no sun at all.

    ๐Ÿ“ HARTLEY FLARELINE, COUPLING AND MOTOR TEST
    2 months ago by jbkiwi ( Fleet Admiral)
    Flag
    View All
    After ripping the new coupling silicone tube a couple of times due to harsh starts from the ESC, (lot of torque going into it suddenly with the new 3650 2550kv inrunner ) I've replaced it again and added a couple of small cable ties to clamp the tube tighter on the splines. Also managed to get it starting a bit smoother with a bit of TX tickling, although not perfect (cheaper aircraft ESC on soft start but still a bit rough,- with an aeroplane it wouldn't matter)

    Hopefully it will be stronger this time. Might have to find an ESC with heli start (like the 'Mystery' blue series HK used to sell if this doesn't work)

    ๐Ÿ“ HARTLEY FLARELINE, NEW BATTERY, COUPLING AND MOTOR TEST
    3 months ago by jbkiwi ( Fleet Admiral)
    Flag
    Tested the new gear yesterday and it all went well till I was playing with the throttle trims and end points and had an unexpected full power no stop situation which ripped the coupling. Went like a fire hose till it did though, and took a lot of power to break it. I had not cable tied the tube onto the ends which were just pushed in, so it did pretty well to hold up like that. One end still had the spline marks, but the other had skidded then ripped the tube down the middle. Good anti stall safety feature for the motor I think.

    Probably withstood around 1/2hp at 25000rpm for about 6 seconds before breaking, so a big improvement on the Mk 2 version. The new motor has a ton of torque and with the new 40/90c 3s 2700mah Hyperion battery is about double the power of the MK2 setup, - 3s 25c 2200mah zippy compact which was a bit tired after 10 yrs for any heavy stuff.

    I had trouble with the sound unit not syncing with the throttle, which required allsorts of trimming to get it almost right. I'm using a one way aircraft ESC, but the sound unit works like a fwd-rev ESC and using a fwd- rev ESC, and needs a center point. I think I have got round it now by switching the siamesed throttle lead (with ESC lead) to the Aux hover pitch rotary on the 9X TX. seems to work just as well, but allows the throttle to be returned to full down-full up mode, and the sound controlled separately, which is good, as you can rev the 'motor' without the boat taking off.

    Some vids of playing with the setup at idle power, and views of the jet mods in case anyone is wanting to do the same to the cheap jets without a reverse bucket.

    Hi Steve, I've managed to reduce the power to about 50% (which is still a lot) after having a play with the TX settings again, (the ESC was not playing ball with the TX settings). All was fine the previous night, but next day when turned on, the throttle was back to the middle again. Changed the end point setting from left to right side (has 120 each way) zero'd everything and changed the ESC from soft start to auto throttle range, and now seem to have the stick back at the bottom, where it should be for a plane ESC.

    None of this is a problem with a plain old std 4/6ch, as there is no fancy stuff hidden in a menu to forget about, and ending up having to hunt for when there's an odd problem. This ESC's been in a crash, so may be dodgy,- time will tell.

    I'm going to try the coupling again as it was before, but if it slips I'll look at the idea you mentioned (was actually hunting through my spring collection tonight for a suitable tension spring to cut some coils off.) Might have to find some HT wire and wind a special one on the lathe, with small legs to grab with pliers, (like mini radiator hose clips, - very little room to do much). I do have some proper wide ones which came with the tubing, but they are too big. I don't think it will need much to stop it slipping, just needs holding from expanding with use and age,- as silicone does.. If the coupling doesn't work this time, I might even just make a dog clutch, then there definitely won't be a problem, (except maybe noise)๐Ÿ˜

    Great work JB,
    Sounds like the coupling worked well and acted well as a mechanical fuse. I would try a making a snug fitting collar at each end instead of cable ties, just a thought.
    Of coarse torque is the killer of drive trains.
    Looks like she should go well with the greater power.

    Cheers,
    Stephen.

    ๐Ÿ“ HARTLEY FLARELINE, NEW MOTOR AND HD COUPLING
    3 months ago by jbkiwi ( Fleet Admiral)
    Flag
    View All
    I decided to change the Surpass 3650 3000KV in-runner for an XTeam 3660 2550KV for a bit more torque and try the heavy duty (hopefully) coupling I made on the lathe. The coupling uses 11mm OD x 6mm ID silicone tube and is a 3 piece unit with alloy ends with splined inner diams which are a tight fit in the tubing. The whole coupling is only 25mm long to fit in between the jet unit and motor mount, (not a lot of room for most std couplings.)

    The previous experimental coupling was silicone tube with a firm plastic tube pressed on, which lasted for a few previous runs, but the last run shredded it completely, so I thought it was time to try my new MK 3 coupling. After I modified the jet unit, (better impeller and min clearance) the 3000KV motor pulled 30A static, and obviously had a bit of torque to shred the coupling. I like the silicone as you can't damage your motor if something jambs the prop,- it will strip or tear and stop the motor stalling. The smaller tubing obviously has its' limitations,- hence going BIG.

    I've run the new coupling up to around 25000rpm with a shaft, and it's very smooth with no vibration. I might add small zip ties to the tubing to grip the splines better.

    Forgot to check on the earlier runs, but the thermostatic fans on the motor (2 in the dummy motor and 1 in the battery compartment) worked well on this last run, which was good, and the fans cooled things down quite quickly, (battery gets quite warm). Both use a 30C thermo switch,- the battery one is just taped to the battery.

    Another test due when the weather clears up, (rubbish at the moment).

    Quick vid before the old coupling let go.

    Hi Trev, I tried one of these (came with the jet unit) but found it vibrated a ridiculous amount, due to the holes being oversized. Tried it in my cabin cruiser and same thing. Had it reasonably balanced with cable ties but have replaced it with my own coupling and it's pretty much silent. My jet coupling has hung on well now I've cable tied it. A problem I found with the alloy spring couplings, is they are designed for light loads at slow speed (for 3D printers etc) and should run only one direction (with the spring wind, not against it) as if you load it too much against the wind, they can distort and go out of balance, eg, If a spring is RH wound, it's best to run it LH so it's tightening, and vice versa.

    I think the best commercial ones for higher speeds would be the type like I've made which Cornwall Model boats sell (2 splined ends and rubber center tube) or with the red plastic universal for lower speeds. I have given up on Chinese stuff as it's just garbage,- they can't drill an accurate hole to save themselves. They obviously don't ream holes, just drill them to size, which is totally useless for anything other than rc cars.

    I've tried all the universals on Ali Express, and they are all useless. For smooth running you need a precision fit. I bought a few reamers for common motor shaft sizes, and used them to get a good fit with my new couplings, and it makes all the difference.

    It would be interesting to know what couplings the guys with the big scale powerboats use, as some of those rev insanely and sound really smooth. Maybe some custom US product ? obviously not Chinese !

    Hi Steve, I was surprised it lasted a couple of runs, as there is a big load on it at full power. The main problem with the silicone I found, (even with the plastic tube reinforcement) is that the torque screws the silicone tube, and makes it climb towards the motor and tries to screw itself into the rear bearing. I put a small collar in front of the bearing, but as you can see by the flare in the plastic tube, it had tried to climb over the collar.

    I had the same problem with the high speed brushed motor I started with in the boat, and I made brass tube and washer stops for that, (same in the runabout) but it still did the same if you gave it some stick. Hopefully this one will fix it, and if it does, it might be my std coupling on any future models.

    Re the coupling letting go near the bank, that was only half of it. When I went back to the jetty to grab the launching trolley, (bank was too steep to grab the boat) the wind suddenly changed and the boat started to head out into the pond. I raced back and thought, "crap, I'll have to step in and grab it before I need to swim for it" One of those times when the brain says "that's a really dumb idea mate!" but the body says "stuff you, I know better". So in I stepped, shoes and all, into 2ft of water with a slimy clay bottom, and promptly sat on my A888se up to my waist ๐Ÿ˜‚๐Ÿ˜‚๐Ÿ˜‚.

    Was up in a flash before I was 100% saturated, but covered in clay and rather damp, (and hoping the residents of the apartments over the pond hadn't seen it and had a stroke laughing, - didn't hear any clapping so might have been lucky) Rescued the boat though, which was the important thing. Luckily I had a few old towels with me and managed to dry off a bit and drain the shoes. I had to wash the clothes and have a shower in disinfectant pretty much when I got home, as you don't know what's in those collection ponds (everything from the roads and land run-off etc).๐Ÿ˜

    All in all a great day, -what more could you ask for,- a play with the model and a swim on a lovely evening LOL. Probably scared the carp out of the eels.๐Ÿ˜‚ Did manage to complete the vids of the trip to the pond which I'll post once YTd Think I'll have to build a rescue boat.๐Ÿ˜

    Hi Trev, a similar type of coupling is sold by CMB and others, but are just pressed into plastic universals. There was nothing available in such a short size other than the spiral aluminium connector it came with. They are only meant for 3D printers etc and they have a 'handed' spiral cut which is only good for one direction or light loads (with the spiral, not against it,-which could cause distortion under heavy loads and metal fatigue.

    The impeller in the jet is doing about 25,000rpm loaded, so needs to be precise. The holes (4mm+5mm) in the ends are reamed to size (not just drilled like Chinese rubbish) and are a light push fit on both shafts and have no movement. Could still be improved by making them from brass, but I'll see how these hold up first. I should probably cable tie them before giving them too much stress.

    Lovely mk3 coupling, looks like a bought one.
    I am surprised that the mk2 lasted as long as it did.

    ๐Ÿ“ HARTLEY CABIN BOAT, MUSIC INFRA RED CONTROL EXTENSION
    1 year ago by jbkiwi ( Fleet Admiral)
    Flag
    View All
    Just received my sack of infra red pick-ups today and had a crack at fitting an extension to the one on the board. The extension is needed as the BT/IR music board is now hidden under the front bunk, and the IR pick-up on it can't be seen by the remote. The extended pick-up is now mounted above the dash and should be in a good position to receive a signal. Works really well, even with the original still in place, (Graham was right, and no smoke๐Ÿ˜) I did order a spare board just in case๐Ÿ˜Š, but can now use that in something else.

    Hi Martin, I did see the question but thought I'd wait for the new bits to arrive and I can do a sort of exploded diagram showing what bits go where. There were a number of wires soldered on this one which might have made it confusing. I have a new board(with remote) and a spare remote as well which should be here soon.

    Re a larger scale Hartley, I've already had the largest scale version possible, but it wouldn't fit in my modelling room now๐Ÿ˜lol Not sure what to do next, as I have a number of projects to try and finish (one includes fitting a Seagull Silver Century motor in a Chrysler 15hp casing) I've just disassembled the old Chrysler motor today ( it did run but parts are impossible to find these days) Plan is to cut the drive end of the crank off and adapt the Seagull drive to it. I've already made an adapter plate for the motor. The idea is to have a proper forward and reverse and neutral and to make it quieter (Seagulls are pretty noisy on a long run) Just a bit of fun!๐Ÿ˜Š If the the Seagull doesn't work, a Chinese air cooled 4 stroke might be next.

    ๐Ÿ“ HARTLEY IMPROVEMENTS,- RADIO

    View All
    Just fitted my small BT player under the front cabin roof to use as a radio. It plays through the BT board but requires an aerial. I have made a working aerial using a spring as a base (so it can be folded down) and a wire soldered to the wire aerial and fed through the spring and through a hole in the cabin. it is attached to an adaptor plug which plugs into the BT player. Works very well and does not require unplugging to remove the cabin. player will only need removing for charging.

    I will now be able to play music from a micro SD card on the BT board using its' remote, from the card in the player via the BT board and the radio in the player via the BT board.

    The BT board will be hidden under the front bunks once everything is sorted, (hopefully with an afore mentioned IR pick-up extension for the remote to 'see'. I've ordered a sack of IR pick-ups from AlExp to try, and another BT board in case smoke leaks out.

    Fleet Admiral JB,

    Nice work.

    When your bits and pieces arrive would it be possible to do a small Thread or 'How-To' on how to connect up the sound system with photos and how to program it to put the music on.
    And where all the equipment could be obtained from.

    This will be something that many members might like to fit in their boats, it will also help new guys to the hobby.

    ๐Ÿ“ HARTLEY FLARELINE, MUSIC FITTED
    1 year ago by jbkiwi ( Fleet Admiral)
    Flag
    View All
    I've trial fitted a twin speaker BT module which is powered by a 1s LiPo. Speakers are 8 Ohm .25W (the board has a 3W max output) I was thinking of fitting a small amp to it, (as per Grahams suggestion) but it can produce some reasonable volume, depending on the recording level. If the recording was done at a high level, the volume will be louder, (as I've found with transferring my vinyl to flash drive, - tapes are a bit harder to do as they tend to be a bit duller- especially after 40 yrs ๐Ÿ˜) I'll see how it sounds on the water.

    Music is running off the micro SD card in the vid, but I can also use BT to transmit from the phone radio, - or music (on micro SD card) and radio from my small BT player (small red player in pics). The remote works with the card inserted in the board, and anything else is by BT. Quite a lot of fun playing with this. Had it running for around 5 hrs from the card and only used .2v from the 2200 mAh LiPo ((1 cell from a dud 3s) I have a 1s 2000 mAh from a vape machine which is a lot smaller and lighter which I would use on the water.

    The board has a limited equaliser, volume, fast fwd/back, next track (by button or numbers, on off etc. Quite amazing for its' size. I have 170 entries on the card at the moment,(mostly album sides with a number of single songs) which took a bit of sorting out. The board sorts/plays them in a haphazard way, which didn't match the order I recorded them in (or alphabetically) ?? I have them all numbered on a sheet of paper now to make a song/album easy to find.

    I was thinking, that once it's all tucked away in the boat, I might extend the IR pick-up for the remote, to somewhere more easily 'seen' by the remote (perhaps on the dash) I've found the same pick-ups on AlExp for a few dollars a bag of 10, (I'll need them, as the pick-up on the board will be destroyed if I take it off. Something else to play with if I get bored.

    The speakers are hidden under the galley top and in the 'head' compartment, in wedge shaped boxes, which will be trimmed and painted before screwing into place. All wires are fitted with JST plugs in case things need removing, and board will probably be fitted in one of the forward bunk boxes (if I can extend the BT pick-up) otherwise the board may be disguised as a squab.

    Roy Phillips (The Peddlers) is still living here (been here since 81 and he's cracking 80)

    ๐Ÿ“ HARTLEY FLARELINE, TRAVEL BOX
    1 year ago by jbkiwi ( Fleet Admiral)

    I needed to be able to carry everything together, to places I might like to try for a better launching video. Problem was/is that there is a 100m or so down a beach to a spot which I discovered, which looks like an ideal area to have a 'play'. If I couldn't carry everything at once, it would be too dicey to make a few trips,-leaving pieces unattended in a public area, out of sight for 5 mins each trip. Therefore the boat box was knocked up, mostly from bits I had left over from house projects. Mainly 5mm ply with 18x18 pine framing.

    The trailer sits on blocks to raise it slightly so as not to flat spot the tyres when stored, and is held in place by a screw at the front and 2 notches at the back. There are Formica 'locks' at the back which turn over the trailer frame at the back to hold it in the notches. The boat is lowered in complete with the trailer, with the help of a cord with a 'spreader bar' at the back The trailer is 'locked' in place then the tow car and radio shelves are inserted.

    The boat and tow car are held in place by sponge pads on the lid, (the tow car springs help hold it still as well, as the lid pushes down on the roof a few mm) There is a shaped piece of thin cardboard which slides down the back of the tow car and folds over the roof,-just to stop the lid restraint cord catching on the tow-bar. Everything fits in with 2mm to spare height wise. The box has a rope shoulder strap for carrying short distances, (needs some padding) but I am looking for some large pram or golf trundler wheels for 'long distance travel' ( some of the prams have clip on/off wheels which would be useful,- might have to buy a complete pram to get the bits)

    Don't worry Martin, it's all well secured and padded, and will only be going on soft sand mostly. I can carry it reasonably easily with the shoulder strap if needs be. I see you haven't lost your sense of humour๐Ÿ˜, and yes, the plane now fits nicely in a shoe box, just have to assemble it at the flying site ๐Ÿ˜‚.

    Jb,
    Thank's
    The only thing about having wheels attached to the box is vibration.
    Will it shake the contents of the box in to sizes to match your plane. LOL!!

    Hi Martin, nice to have you back! You are right, one of those electric golf trundlers would be ideal ( a lot of Chinese use them here,-lazy buggers, more money than sense)๐Ÿ˜ Thought I might just use wheels at one end, as I might not be able to get too much in the car with the box in there. I'll see how I get on once I get the opportunity to give it all a try, (rubbish weather at the moment, even rain!!! wooha, )- need it as the ground is like concrete with large cracks a foot deep!

    Not sure what's next, (maybe rebuilding the last plane I built, and just test flew for the first time since I built it early last year,) - didn't end well๐Ÿ˜‚,- lots of bits,- my wing design was flawed, See before and after pics for a laugh. At least the fuselage stayed in one piece and can be re-used. Back to the drawing board ๐Ÿ˜€ Can't make up my mind on future boats yet, - still thinking.

    I now have sound in my 'Jeep' towing vehicle, which is another mod, (I seem to be obsessed with adding stuff) (vid) and I'm waiting for a good day to try another video (never satisfied as it's hard to get things spot on by yourself, - operating a video, boat and tow vehicle all at once is a mission in this case!, especially while trying to keep yourself and your shadow out of the shot. All that stuff keeps you busy which is the main point I suppose๐Ÿ˜.

    Don't over-do it trying to catch up all at once, will you?!

    Hi Jb,
    Well i have done a bit of catching up on this project and the amount of experiments and added bits is amazing.

    Even the transportation case is fantastic.
    I can see a modified RC Golf trolly being used/attached to this case to save you carrying it.

    So is it a secret as to what the next project will be ?

    Now there's an Idea Graham !๐Ÿ˜๐Ÿ‘ - perhaps powered by a small 4 stroke mower engine with a centrifugal clutch, 21 speed Roadranger transmission..............๐Ÿ˜ don't get me started lol.

    Hi JB,

    Nice box. What you need now is to put wheels on it and attach it to an RC truck like this ๐Ÿ˜‚๐Ÿคฃ

    Hi Peter, box is not really flash, just made for the job. It's always a problem moving countries with models. I spent days packing a number of planes, boats and a helicopter back in the late 70s to take them back to NZ from Norfolk Island (only about 500 miles away), and when I got to the customs here in NZ, they made me take them all out (even had to undo a few kits) so they could look inside them๐Ÿ˜ , no way I could get them packed up again. Had to try and carry a huge mess on a trolley to the waiting car. I'll be interested to see how you get on with yours. Sometimes I've found, that good strong cardboard boxes with polystyrene sheet side packing, and then filled with polystyrene packing chips does the trick, -recently sent 2 helicopters I sold, down south like that, and they arrived in one piece.

    Problem is, unless you can take them in a car with you, you don't know how people will treat them. Moved possessions to and from Fiji by ship about 20yrs ago, and had some things clearly marked ''don't stack anything on top-fragile!!" made no difference at all, came flattened anyhow, (luckily not too much damage due to me packing them really solidly, (lots of padding, tape etc) You can never pack well enough for idiots! Wooden crates are the best, but you pay for the weight. Good luck with your move.

    Even the box is the Bees Knees. I will be making a box to move Dusseldorf to Hungary. There will be a picture on my retirement thread but I almost feel embarrassed to post it even though I have not made it yet. I am afraid that yours is much nicer than my effort will be.

    ๐Ÿ“ HARTLEY FLARELINE, TOW VEHICLE MODS

    View All
    Just tried the new 'handbrake' on the tow vehicle with the boat attached and it works 100%. Will actually stop the whole unit while rolling down the slope, and with a bit more weight in the back of tow vehicle, it should be good for another launching attempt at a proper ramp. Answering your question Steve, water seems to make little difference, (actually seems slightly better)

    Thanks for the kind comment Steve, it is a trailer boat after all and I thought a stand wouldn't look quite right. I actually towed the original with a Farmall 'A' which I had done up, but there are no scale RC tractors that big, which is a shame as I think it would have looked better. Might find one one day.

    2 years ago by jbkiwi ( Fleet Admiral)

    I know it's not a boat, but it's attached to one ๐Ÿ˜ - I've been trying to do a decent trailer launching vid, but have had a problem with the vehicle having no 'handbrake' to stop it (and the boat) rolling back on the big boat ramps which are quite steep. It's also hard to find just the right spot where there are no people, nice slope to the water etc. I have now come up with a simple driveline brake (think Landrover) which works pretty well on the vehicle (yet to see if it will work with the weight of the boat and trailer,- could need a lump of lead for traction). The cord is wound round the driveshaft so that in reverse, once the servo pulls on it,
    it automatically wants to tighten itself and grips quite well.

    The servo is plugged into the rotary switch on the TX,but so the braking can be applied gradually for control when backing down the ramp (at least that's the theory๐Ÿ˜) another turn or two on the shaft will multiply the braking effort if necessary. The vehicle is also very low geared 1000 RPM@12V geared motor and the diff is about 4:1 so will idle up the slope in the pic. Tows the boat and trailer easily ( about 8lbs) but could do with a bit more weight for traction (vehicle weighs 1.8kg).

    Always something to play with, improvements to make๐Ÿ˜

    Hi Steve, only one way to find out I guess, although it shouldn't need to go in the water more than up to the rear axles to launch (especially in salt like the first attempt) - would depend on the slope. Going to give it a go on the back path this arvo with the boat on. Even if it got wet, it should be good enough to hold the vehicle and trailer once the boat is launched. I'll test your thought out as well.

    Ingenious JB,
    Will it still work if the cord gets wet?
