Happy Hunter by jarvo Fleet Admiral!   Posted: 14 days ago
No worries mate, have the esc's got a max and min voltage??? they may not work at 6volts, if not then a set of 7.2v NimH packs will be brilliant x2 or possibly 4 packs with a Y lead for each pair, 3300mah packs are going for a good price on ebay at the moment, also have a look at component shop and hobbyking, be sure you are on the uk site to keep the postage down!!!! Wouldn't bother with lipo batteries, SLA or NimH are more user friendly. If you want the H/H superstructure try contacting Krick they now make the kit, took over from Robbe when the went bust. Are the propshafts ok??? withdraw the shafts and lightly oil them get the oil into the inner bearing as well. Mark

Power Cabling by NPJ Captain   Posted: 15 days ago
So following a long away week-end of Astronomy, now trying to get a bit further before going away for a couple of days. As I start to wire up the power circuit I realise how important it is to think things through first! Made up the link from the Battery to a ‘choc block’ distribution point which for space reasons is under the ‘control’ platform which will fill the bow area. (Pic 1) The fuse boards were obtained from Component – shop.co.uk Ltd in Bangor which is a good source of all sorts of electrical bits for us and is in Wales! (Pic2) The Dual Esc/Mixer, from the same place, a P94 9Lite), I have secured with Velcro (Pic 3) and I hope to keep the battery on top of this with a little air gap. It is at this point that I really came to appreciate the space limitations (Pic 4) and I do not have the motors wired in yet which will have fuse boards on the ‘platform’. (Pic 5). Next time hope to wire in Motors and Fuse Boards, Sound Generator and Receiver. Then see how it sits in the bath.....! NPJ

46" Firefloat What Motor/Battery by jarvo Fleet Admiral!   Posted: 23 days ago
Hi J. Your motors are nominal voltage 7.2v. Try a single 7.2v 3300 NimH pack, quality from Component Shop. It will be short running time, powering 2 motors but will give you an idea of performance, then you could buy a second, 1 for each motor, if this did not work out or you want more performance then go for brushless motors, still with the 2 battery packs. I would try the single pack first, suck it and see, develop it from there without breaking the bank!!!! Cant see any ESC, have you got 1 or 2? if 1 use a 'Y' lead to connect the second battery. Mark

Voltage step down by Novagsi0 Commander   Posted: 25 days ago
Just a thought- The component shop does do a voltage reducer rated at 6 Amps power draw, and will drop from DC (10.5-40v to 1-9v) I thought about using one of these to run a 6v volt Marx Hectoperm motor from a 12v source, to save buying a new battery. As long as your motor speed controller setup doesn't draw more than say 4~4.5 Amps. I'm my case the tug had 4 x 6Ahr 6v batteries wired in parallel giving 16Ahr and 2-1/2 hours running time @full speed. These batteries have since all died due to age. I wanted to use just 1 x 20Ahr 12v battery instead and keep the added ballast I need anyway. This 6 amp unit is on the limit in my application. P.S i'm tight with money and I acquired the battery free from an alarm battery swap.

Battery ordered, and a charger, from Component Shop. Thanks for the guidance. Brian.

Electronics Down Below (5) by NPJ Captain   Posted: 26 days ago
This time I will try to remember to put in the ‘source’ information on the bits and pieces I use........... In the most recent piece I should have included exciters/transducers are Dayton Audio DAEX 25VT -4, 4 Ohms – 20 Watt pair, obtained from Sound Imports Netherlands and very quickly as well. The sound unit is a Mtroniks Digisound 5M diesel sound, available all over the place. Now to look at where I am at. Exciters are in place as high up the Hull as possible, but remembering the Deck level. Used the adhesive pads as supplied after wiping that part of the Hull with Meths and Silicone adhesive to keep in place as well as using the wiring tidies from Modelsport Ltd., for the cabling. (Pic 1+2) Before I start the motor and controller wiring I changed the platform ‘up front’ (pic3) with a piece of thin ply which I have given a couple of coats of varnish to waterproof. Then I thought to myself “why am I waterproofing this when, if it gets that wet, it will have gone to the bottom and be useless anyway”! (Pics 4) However, the platform gives a little more choice in terms of layout of other components and my plan for them is not really settled yet. I am concerned about the stern and possible swamping, but it currently seems the best place for the upgraded battery. (Pic5 ) Whilst talking batteries, I have gone for a separate battery supply for the receiver and hope to use the Bec supply for running other less critical items. Also the fitting of the battery in the stern bay drew my attention to the rudder servo for a couple of reasons. First is I am still considering increasing the size of the rudders and I am assuming that will increase the strain on the servo. The servo supplied is a standard issue and not water resistant so I have gone for an upgrade as shown(Pic6) That gives torque increase of 17Kg/cm over the Hobby Engine S1040C and has metal gears, metal control arm and waterproof for 20grams extra weight. Second is the closeness to the new battery position. So I was going to alter the servo arm setup anyway and the new metal arm suits this well. Maybe my ‘tutors’ will consider all this to be a little ‘over the top’ but I do so enjoy messing......................... New Servo DS 3218 by AYANI from Amazon. (Pics 6/7 ) Following that distraction, back to the front end and the Motor/Mixer placing and wiring. Now a little time ago I drew a plan to see what could go where and it came out that most of the ‘bits’ would go in the front bay with motors to be wired once power was brought forward, followed by the Esc/Mixer. (Pic 8) At that time I bought a P94 dual esc/mixer from Action Electronics and got the 20 amp version to be on the safe side................. My ‘guardians’ did point out this was ‘over-kill’ but I had already got it. Now, when placing the unit on the mounting board I found that the heatsinks made it too high to fit in the Hull! So being a spoilt brat only child I ordered the 10 amp version and as usual it came very quickly from up here in Bangor. ( Will keep the other one for the next project............Happy Hunter??) Unboxed it and it looked just the same, heatsinks and all. (Pic 9/10 ) So at that moment there was a bit of a set-back so I rang Component Shop at Bangor, they said “take the heat sinks off and you have a P94 lite”! Such a simple answer and such a nice chap. (Pic 11 ) Now a quick 'measure up' before I have a glass of wine (Pic 12) and does it all fit...? Well it appears to at the moment! (Pic 13) Next time really going to screw down the components under the forward hatch and wire it up. NPJ

RSS P71 Sovereignty by RNinMunich Fleet Admiral!   Posted: 1 month ago
Many thanks for the Turnigy tip👍 much cheaper than the 20 quid Action /Component Shop version 😉 I hated wasting channels, and multi-channel sets were horrendously expensive😡 so many many 🤔 moons ago I made my own 4 function switch decoder for my destroyer, home made PCB, a few 5V CMOS chips, driver transistors and 5V 5Amp relay outputs. Pics 1, 2 & 3. Gave 4 functions Nav lights, Signal Lamps flashing, Whoop Whoop siren, and smoke unit from one proportional channel. Still seems to work 30 years later!😊 Around the same time I added a winch for the crane on the stern deck and also made a home cooked PCB with a simple forwards / backwards motor driver; again CMOS chips, driver TRs and relays. Pics 4 & 5. Pulled in well but there was no free-run mode on the winch so it needed something like a tin o' beans on the hook to run it out 🤔 . Lovely smelly etching for the PCBs 😆 Ferrous oxide!? Or was it ferric chloride? Never did like chemistry, I was a physics man. But it worked😊 Most of the bits were sort of 'lying around' at work😉 BTW: if anyone needs CMOS or 7400 series TTL chips I still have pretty good stock! Nowadays it's all plug n play and such things are miniaturising so fast one day they'll disappear up there own whatsits! Back then half the fun was doing it yourself and squeezing the utmost out of a 2 or 4 channel radio. Happy days? 🤔 Cheers Doug (AKA Rambling Man😁)

rotating radars off mast by Dave M Fleet Admiral!   Posted: 1 month ago
Hi Seafarer You can buy very small 4 wire stepper motors that will fit. I bought a ruck from China via E-Bay for a few pounds and they work fine. The smallest is less than the size of my little finger nail and I need my scope to see the wires which I sourced from Component Shop at Haydock Show. You do need a stepper motor driver and can control the speed down to single steps with a simple pot. I used an Arduino to test and the program is on the Arduino website. When I get time I might just do a blog showing how. Dave

Blackpool Model Boat Show by 4clubs Fleet Admiral!   Posted: 2 months ago
Attended the event again this year. Wow! was impressed. 28 traders 21 clubs according to the brochure. The place was very busy and lots to see lots to buy. Lighting was good, refreshments available in the hotel front lounge. Not just boats but trucks etc in the other room next to main hall. Ian from Component Shop has really turned this event round. Hoylake Model Boat Club have ordered 10 tables for next year and will be attending. If you have been put off in the past give it a go next year. 😊

Hobby Engine 'Richardson' Tug Upgrade by RNinMunich Fleet Admiral!   Posted: 2 months ago
Yep, a Large scale IC doing most of the work, RX/Decoder, and some power transistors for the outputs. Not easily mod-able 😡 Suggest you have a look at the little switch boards from Action (Component Shop) Neil. http://www. style='background-color:yellow;'>componentshop.co.uk/action-electronics/switches.html I made my own several years ago using CMOS chips and little 5V relays, but then I'm just like that😉 The Motor Sound Unit I understand looks after itself as it's coupled into the ESC control. So you just need switch boards for lights (nav and deck/cabin lights), smoke, other sound boards, e.g foghorn and/or ship's bell from Action? Have fun, Doug

MFA TORPEDO 500 / BATTERY INFO by al2612 Seaman   Posted: 2 months ago
Tx Doug - Looks like another piece of kit to put on the shopping list. Previously had just used a charger from Component Shop and when the lights stopped "blinking" to me that was it. Nothing is ever that simple 😉

Removing The Deck by Dave M Fleet Admiral!   Posted: 2 months ago
Only way to see if it works is to make a test rig and hold the exciter in place to see what it sounds like. Don't use the glue pads for now just hold in place with light pressure. Radar should be ok weight wise. All batteries should not be charged in a model, ever! They all contain chemicals and if a fault develops or they leak explosive gases the last place they should be is in an enclosed environment. There are high power NiMhs that may be suitable as they can be had in different formations. Component Shop will make up a pack to your specs. If you rush the only thing being spoiled will be the boat!

Hobby Engine Richardson Upgrade by RNinMunich Fleet Admiral!   Posted: 2 months ago
PS to Chris, Assuming an optimum speaker / transducer, to get more volume you need a more powerful amplifier, more Watts! The little stand-alone boards rarely produce more than 1W. Again check the Component Shop. Also check that your speaker / transducer is rated for the higher power!! If using a traditional speaker with a cone make sure it is a waterproof Mylar cone!!! 'Uvverwise' they can go awful soggy an' droopy 🤔 Cheers Doug 😎

Hobby Engine Richardson Upgrade by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Chris, to feed two or more audio signals (Sounds!) into one speaker or transducer (which is just the core of a speaker without the cone!) you just need an amplifier with a mixer input. Not complicated but to make it even simpler people like Component Shop (Action Electronics) have some - http://www. style='background-color:yellow;'>componentshop.co.uk/action-electronics/amplifiers Cheers Doug 😎

Hobby Engine Richardson Upgrade by octman Captain   Posted: 2 months ago
I have an old Southampton , off E.Bay a couple of years ago. I fitted the Components shop mixer, 2x 3400mAH NiMh packs(one for each motor)2 Mtroniks 15A Marine vipers, Technobots diesel sound system and also a Technobots 16 channel sound system. There is not a lot of spare space! I had a problem with the mixer eventually. It worked very well, as I did not think the turning circle in the original form was very good. I took it out eventually and went over to tank steering, which is OK but seems to be more effective in turning one way rather than the other, it's fine in a straight line. I found out after I had removed the mixer that the supposed problem was of my own making. So many wires inside that I was not in fact charging one of the battery packs so it ended up flat. Nothing wrong with the mixer at all! I mounted the engine sound speaker in the lower half of the cabin,where there was just enough room, where the window openings are not glazed(at least on my boat they aren't). Sound was OK but it was a bit lacking in volume, but I may need a higher power speaker, not sure as audio is a non area to me. The 16 channel unit is good in that a micro SD card is supplied with pre- recorded sounds, and instructions are given on how to record your own. The difficulty with this particular sound system is finding somewhere to put the second speaker as the 2 systems cannot be fed into the same speaker. It was a bit faint to say the least,possibly due to the tiny speaker I used. I tried to fit a transducer glued to the underside of the deck but there was no improvement so that is a work in progress. The inside of the hull resembled a very untidy birds nest! CHris
