hi ya Colin, sorry for the delay - but I am going to open up a can of worms here. Although a lot of people use the 'Y' tail or the 'W' tail mixer from MTroniks or other Companies to actually mix two speed controllers and a rudder movement in the marine environment, (personally) I don't think this is effective as a dedicated marine mixer. The reason for this, is, I built the Forceful tug a little while ago and I incorporated the 'W' tail mixer in it for independent control of the 2 paddles and the rudder and when this model did 'sea trials' 😊 on the lake & in the test tank (the bath) 👍I was never 100% happy with this. It didn't seem to perform quite right, especially in reverse. The model seemed to go better in one direction than the other. One motor always seemed to lead the other motor so therefore the model would steer off course and you were always correcting it. When I eventually checked the speed of each motor individually with a tachometer I found that one motor was indeed increasing in revs so - I took out the 'W' mixer and went for tank steering (using 2 individual sticks on the transmitter). This was a lot better and saved the day at the lake. Then I wend and had a look at what mixers are available and yes there is the ACTion P94 which in my eyes is extremely expensive - but - there are one or two on Ebay market but also there is a guy called Alan Bond he runs a company called Forge Electronics and they make an independent mixer which I use myself. I find it extremely good. 👍 the name of the game though is for yourself to try setting up the 'W' tail mixer and playing around with it or you could look at individual mixers that do not have the speed controllers built in with them i.e. there is one from ACTion as well, there is one from Forge and as I say there are 2 or 3 off the web market place. Have a look - here are a couple of pics of the Forceful and my set up. The speed controllers I am using in this tug are Electronize and it's Alan Bond's original mixer which used to be sold from Technobots - but he opened up business on his own and I will put a link on when I find it. http://www.forge-electronics.co.uk/http://www.forge-electronics.co.uk/
Hi Colin, Try this version, P94 for brushed motors, from Action Electronics at Component Shop. Only throttle and rudder inputs with automatic mixing. I have one of these I intend to use for my long thin destroyer, or maybe the Graf Spee. Or the P40 for Brushless, same operating principle. https://www.componentshop.co.uk/action-electronics/mixers-mu... I may get one of these for my PT109. heers, Doug 😎
Hi Sandgrounder, Good stuff from Canabus BUT- If you are going to parallel connect batteries there are some safety rules to observe to prevent potential fires on board - ESPECIALLY IF USING TWO LiPos!! The two batteries must be identical types with the same capacity and state of charge. Otherwise the one with higher voltage will try to charge the other. This can result in high currents which represent a high fire risk - most especially with LiPo Power 😡 To prevent this you need a pair of high current blocking diodes between the batteries - fast Schottky diodes. If you are electronically minded this is easy to do yourself. If not, Component Shop market an Action Electronics module to do the job. Spec attached as PDF. Link to purchase is below You can buy the board here (No I don't have shares in the company but have used several A.E. modules and they are well made good quality👍) https://www.componentshop.co.uk/p103-parallel-power-board.ht... I think 15 quid is a good price to protect the rest of your investment 😉 Have fun, cheers, Doug 😎
Sounds good to me Selwyn 👍 That board is a sensible (essential) idea in that setup. Stops a stronger battery trying to charge the weaker one.👍 I have several Action Electronics modules as well (duplicated some 😁) They're good, well made stuff. Anyway, your brushless ESCs will 'see' 12V so setting them up as running on NiMh should do the trick. If you set them up as 'LiPo' they might think it is a 3S 11.1V battery and try to let the volts go down to 9V before cutting off!! Not good for the SLAs 😡 IF they assume it is a 4S 14.8V Lipo they will cut off at 4x3.0 i.e. 12V which will drastically shorten your run time; you'd have to keep the SLAs near fully charged (13.6V) all the time. Bon chance mon ami, let us know how it goes. All the best, Doug 😎
Hi Doug I’m using 2 x12v SLA wired through an action electronics parallel board to give 12v. I hope to feed the power through the existing action electronics fused power distribution board which will feed the two esc and all my on board lighting, radar scanner etc. Cheers Selwyn
Hi Jon. I wouldn't be surprised if it would make £300. I have looked around for about six years and never seen such an origional and unmade FPB kit. I have put a sound system in mine supplied by action electronics. The sound is of a turbo cat diesel and is very effective. Regards Kevin
Hi TJ, RE: RX battery. Any 4 or 5 cell (4.8 or 6V) NiMh of 1000mAh up will do. Use the biggest one you can without upsetting the boat's trim or reducing it's performance / planing etc. BUT: don't forget to disconnect the red wires between your ESCs and RX to disconnect the BECs in the mTroniks speed controllers!!! Also check that your RX and mixer module etc can handle 6V+! If not use the 4 cell pack. A fully charged NiMh will be significantly above 6V. Some modules; e.g. Action Electronics / Component Shop don't like that 😡 Alternatives are, esp if you need to save weight, 1 use ONE of the red BEC leads from ESC to RX, e.g. the centre one, and disconnect the other two, 2 Use a separate 5V UBEC module to syphon power off the drive battery for the RX, AND disconnect all three red BEC wires from the ESCs. Cheers, Doug 😎
If you want a selection of various engine sounds, plus extra sounds i.e. klaxon,seagulls,winch sounds etc, the best one for the money is by Action electronics👍, part of Component shop. http://www.action-electronics.co.uk/engines.html Peter😉
Post 2 Range Launch? The bath test has shown up a leak……………….. Have not tried to find where yet but it is hopefully in that small bay as it did not flow over the rib section. Strange I had not thought leaks to be much of a possibility in a boat! Wishful thinking again. Anyway it has put work back a bit. You will notice that the bath water was ‘used’ condition. I was not allowed to waste water due to the shortage so had to use the bath with Radox and herbal Oils in it. I trust it does not affect the paintwork…………… Any opinions on Leak Checking? I did check how it ‘sat’, and the waterline at its current weight. There is something in those images that RN Munich will pick up on! Have received some of the parts………….just like Christmas for me. ( I was a spoilt only child). Two issues strike me. a. It may be of interest if I give sources of the parts b. I think I have a problem with ‘scale’………….. Currently the purchases fall into two groups, electrical and deck fittings. The electrics are not posing a problem yet, but the size of deck fittings certainly is! Taking the larger ‘electricals’ first, I have gone for pre built units. Someone with more ability could build the units themselves. Kits are available. Also far fewer units could be used to start with and added later if needed. As a result of my previous, though small, experience with the Richardson Tug I used Action Electronics and Component Shop in Bangor, Wales for almost all of the electrical bits. They are helpful and efficient with good quality products. I am still using Mtroniks DigiSound for the sound unit, but Action Electronics now makes one as well. I have used a new source for the transducers/exciters. I have previously used Dayton Audio, sourced through SoundandVision Netherlands and costing around £35.00 for a pair of TT25’s plus mail. This time I used Mr RC for similar item, made by them for about £53.00 the pair mail free. They too came from the Netherlands! Not tried yet, but have noted that the Dayton Audio ones had a foam ring on the face which was self adhesive and easy to place. Mr RC require Gluing in place. Going to look for the leak. Next post should be on the electronics which I hope will have arrived by then. BTW, The 46 Firefloat Mk2 blogg by ‘Elsrickle and Fire Boat (Crash Tender) on our site are great sources of information. NPJ.
Hi, Put the original radio board, smoker and light wiring back in. Take out your new RX and ESCs and use them for something else. Then fit a P94 dual ESC and Rudder Mixer from Action Electronics, sold by Component shop. You will get the same effect when used in Mode 3 👍😁 You will only need the 10A version for the Richardson. https://www.componentshop.co.uk/p94l-dual-esc-and-mixer-2-x-... Only difference with the 20A version is chunks of ally on the power transistors as heat sinks! Easy enough to 'self fit' 😉 Have fun, cheers, Doug😎
Your answer even quicker 😲 OK, if you don't want to practice twin motor control using two sticks, like tank driver, then I suggest the Action Electronics mixer board (as discussed during your aborted tug conversion🤔). You'll probably need the 20A version with those motors. Cheers, Doug 😎
Hiya Doug Yep but I prefer something I can Hold in my hand to read . No booting up time req,😁Have you heard of Action R/C Electronics It's an arm of Comp Shop. Same addy . Great units ready built : or kits for many of them. Download the catalogue from Comp Shop site. I find Kyje very helpful when I have a query,but they are all good. Steve Webb /Servo Shop also handy too. Cheers Doug👍
