Hi I am using a Blue Rain esc rated at 60 amp 480 amp stall current .Has all the features of the viper plus a finned heat sink and cooling fan . Powers 2 black and decker 600 drill motors with Graupner series 162 props motors approx £3.50 and esc £6.43 All on E BAY Or motors can be had from Potts in Derby .The motors draw 30 amps at full speed and I use a 5000 3 cell lipo The expensive bit Hobbyking supplied .The boat is a Jules Verne Cheers Ian T
Wouldn't call a Precident Perkasa a quickbuild, runabout or ARTR even though there isn't much realistic detail involved, the Hooben however is another matter with every little detail reproduced with superb accuracy. Life is hard enough as it is why make it harder. You are coming across as a pretentious perfectionist who puts down others who don't subscribe to your personal ethos. Not all members are talented miniature marine engineers but still have the same enthusiasm for the hobby. No one should decry them for there lack of skill, if RTR, ARTR, quickbuild or runabout is the limit of there ability, so what !!, they still enjoy the hobby and that's what it is all about. There are many roads to travel before one reaches there destination and the route one takes is up to them ! John
Thanks, did the video PLAY? It's not showing up on my end. For smoke fluid, I used some Baby Oil (mineral oil), and some glycerin. Using an eyedropper I used about 5 eyedropper of baby oil and 1 of glycerin. 5 to 1. The Glycerin was purchase from a store that sells cake decorating, it's used in icing, in the states, Michaels, Hobby Lobby, Walmart, etc. I would think that pharmacies would have as well. The baby oil is Johnson's. Thanks for the comments, Joe
Hi Ron. I am currently building the Aeronauts Pilot Boat Kit. It is reasonably well advanced now but I still have to fit the electronics. I bought two 400 sport brushed motors and was advised at a very early stage that two speed controllers were necessary. I looked into various solutions and found that Hobbyking sell a dual speed controller especially for two motors. It is a Hobbywing Quicrun 860. I hope this helps.😊 Peter.
Steve. Since my last message, I have made progress, purchased a kit from Cornwall Models. Started building hull just before Xmas and as you mentioned, you need to have patience to get it right. Before going to far, I am planning how to set up the Motors and the Speed controller. I have got a Viper Marine 25 ESC and 2 Motors (380's). Looking back at some photos of yours, it looks as you have 2 Speed Controllers. I am having problems in getting the ESC to talk to the 2 Motors. Do I need to have a second ESC to operate the 2 Motors? How would this be set up through my Hobbyking Controller? Would appreciate some clarity of my thinking. Best Wishes. Ron👍😁
After building the mine laying rails I then purchased scale German mines , only to find out that they are 4mm wider than the rails on the boat, ...what to do , cut the mines (8) down and rework the base and wheels to fit the boats rails or move the rails wider ..... moving the rails ... slow going , found that the motors I have are more aircraft/drone use per the esc, , no reverse .... Hobbyking does have esc that will work , still need a couple of servos and a radio , just not sure if a 6 Chanel land/ boat radio or get a large channel stick radio would be better ... as always $$$$ is an issue . Work on the messy table as I fit cut and replace fittings and supports ... Smooth sailing to all... Bill G
Ed, I get my styrene at a local train model shop, all of the other hobby shops closed down. It is from Evergreen Scale Models and they do sell on-line as well. Evergreenscalemodels.com I buy both the shapes and sheet styrene and I cut all my materials with single edge razor blades as a, sharp blade is always good. Buy bulk packages and go thru a couple a day. See photos
Have just made a prototype of a fan forced smoker which seems to be working well (despite breaking the heater coil by moving it while hot, - had it apart, broke wire, screw and washer repair, not quite as hot) I bought a couple of Heng Long smokers (for R/C tanks or cars) to play with, for $10 NZ each(or 5.3 Euros to you Northerners give or take a yen) from Bangood and just bought another from Ebay. There seem to be 2 different models, as one has a long coil with a lamp wick draped over it, which is sitting in the oil reservoir, the other has a small coil inside a piece of heat resistant woven tubing (as you might find insulating toaster/heater wiring etc) which acts as a wick and that also sits in cotton wool in the reservoir, (this seems to be the better of the two) Tip - don't fill the tank right up, only enough to soak the cotton, element should be just out of the oil. The wick loads the element. The better model seems to have a black top to the tank (also maybe either brown or black tank) and the other has a brown top and dirty brown tank. As with most of this stuff you won't know till you get it what it's going to be. What I did was remove the tank and cut off the pump tube just in front of the screw lugs (see black line in photo) then fitted the tank, and a 40x40x10 5v ESC fan (voltage controlled by a UBEC set to 5v on the jumpers) into a plastic electronics utility box from Jaycar (our local electronics and hobby store). I made up a double JST lead for the 2s 1800Mah Lipo and fired it up (using baby oil). It's pretty much silent and smokes well once it gets warmed up, ( starts smoking in about 5 seconds) You could control it (on/off volume) by either a remote on/off switch or perhaps a small cheap 10A brushed ESC. I would leave the fan running and control the element to avoid burning the element. The original pump tank inlet hole seems ok as is (approx 1.5mm) but you could enlarge it very slightly to get a better flow if you could find a better oil. At the electronics store they have proper smoke machine oil for $20 NZ per litre so I may have a look at that. The reason I went for the fan idea was that I found in std pump form, if I immersed a tube from the tank in water, it sucked water back into the tank. I was hoping it would pump smoke out of my HSL exhausts at water level alongside the cooling water but it would need a very light non return valve to do this. The fan seems to pump the smoke through 2mm ID silicone tube ok, so tubing of similar ID to the OD of the tank outlets should work well. These pumps in original form work pretty well for the price, and are cheap enough to keep a few for spare elements, the only thing is they are a bit noisy but in an 'engine sounding' way, (might add to the effect on a tug or work-boat though) What you have left after this mod is a very handy little geared motor with an eccentric output wheel which could be used for winches, radar and whirly bits of any description (see pic of motor leftover and original) To avoid burnout, these should be run on no more than a 2s (around 7.5v-(suggest 8v max with fan running) The other tank is going to work a lot better than this one but I'm not making a tug, just want a bit of exhaust smoke on start-up etc to go with the 2 sound units. Very cheap to make (around $25 NZ with pump, box, fan and UBEC all through Ebay, Aliexpress and Bangood (and local electronics store) If you wanted to run an ESC to control the smoke and you have no channels left to control it proportionally, you can always try using a second receiver bound to your TX, (if your TX will allow it,) power it and a brushed ESC (wired to the element) as normal and use the throttle channel to plug in your smoke control. This should work if you want more smoke as you accelerate or if you are using only 1 stick on a 2 stick TX you could use your 'elevator' stick pushed up (or a toggle switch if available) to start/stop the smoke (through the brushed ESC setup) . This setup weighs 100g (10g more than std) The quest for lots of smoke continues Will try to upload vid later and update progress.
Forward thinking, that's a must for this hobby as you can always guarantee that the designers don't always think of everything. (I suppose that's why VM have asked you to trial it) Its looking good, I always like seeing the build details as hidden construction is not always appreciated when the boat is complete.
Continue to mockup exterior a bit, still just rough paint, needs work prior to final colors and finish. Shown in the photos are a Switch Holder made by Dubro, a hobby parts maker in the US. This holder uses a slide switch and allows for through the hull mounting. I use this because I want my switch to be activated without having to remove a hatch. Since my large hatch limited where I could fit the switch, I ended up having to mount it on the bow, not the most desirable position due to bow waves. So I built up a mounting from a plastic pipe fitting, a grommet and a screw cap, tried to make it look nautical. This will raise the top of the rod hole high to further weather proof it. See picture with rod only, I replaced the Dubro rod with a longer one that I made from steel rod I had, threaded it and it works. Will trim the length and attach a finger bulb on top. LAST PHOTO -- EVER FEEL LIKE SOMEONES WATCHING YOU. Cheers, Joe
Bom dia Wingcoax, If I want something pronto I go online to Conrad or Krick here in Germany and usually get the 'stuff' in one or two days. If I order from Turnigy/Hobbyking I make sure the stuff comes from the EU warehouse. Then it's usually here within the week. Most of the stuff has reasonably understandable instructions, or I can find it on the web. Learned that the hard way with a delivery from China that took several weeks and and then cost me a small fortune in German customs duty 😡 Model shops around Munich are basically model railway, aircraft or toys🤔 Such is life today! Cheers, Doug 😎
The HobbyKing ESC I’m using has the facility for water cooling and as it will be in an enclosed location without any free ventilation it seems sensible to utilise this feature. To keep the water circuit as short as possible I will put the pickup just behind the propeller and the exhaust on the stern but as the boat has a bulkhead just in front of the stern skin I need to make an access hole through it to allow me to secure the nut on the stern skin. I made a hole through the bulkhead large enough to get a socket on the nut and reinforced the hole with a ply plate, similarly I reinforced the inside of the stern skin where the outlet passes through it. When I was happy that the arrangement worked and I could attach the hoses and securing clips easily I glued and pinned the stern skin to the hull. The water pickup is a standard one that is readily available but it’s supplied with overly large and ugly fixing nuts, the inside one is of no consequence but I thought that the outer one needed smartening up so I put it on a threaded rod and locked it in place with another nut and put that into the chuck of a drill and used a file to re-shape the nut to a pleasing taper….who needs a lathe......😜 I had to reduce the height of the inner keel former as the pickup tube is not long enough to get a good fixing with the internal nut, as the inner keel is balsa I fitted a ply reinforcing plate to spread the load. The last ‘photo shows the location of the ESC, main battery fuse and receiver. The hoses will be secured to the ESC with spring clips throughout. I found that the silicone tube I use tends to kink rather easily if the radius of a bend is too small and I found it necessary to form a tight spring coil around the piece that loops the water back through the ESC to prevent this happening.
