spektrum DX6 tx by RNinMunich Fleet Admiral!   Posted: 2 hours ago
Hi Both, maybe this helps. https://www.youtube.com/watch?v=fhQHmQIaigY https://www.youtube.com/watch?v=d-5G7BVWEhI worked for me. 😉 Good luck, Doug 😎

I wish I knew that too, Someone please make it clear how to link a spektrum to a receiver.

I`m having trouble binding my DX6 tx to a Spectrum AR610 rx. Any advice would be appreciated !

Prop Shaft Grease by kmbcsecretary Chief Petty Officer   Posted: 16 days ago
I've always used my own mixture in my boats and never had any problems Use a mix of silicone, copper slip mixed with a little castrol gtx to make the mix like creamy consistency as found like most of you know that the grease gets thrown to walls of the shafts tube and just sits there not doing anything to lube the shafts

Voltage step down by Dave M Fleet Admiral!   Posted: 25 days ago
Why not use the 12v battery if the ESC is Ok for 12v. Restrict the tx stick movement so that just 6v goes to the motor

Twin motor control problem by RNinMunich Fleet Admiral!   Posted: 1 month ago
Hi John, earlier you wrote "Sometimes I have control of the speed on other occasions it has gone to full speed reverse and I have no control." Full reverse and non control is the classic case of aircraft Failsafe - Throttle full back!!!! You need to reset your TX to Throttle OFF for failsafe, and then look very closely at where your antenna is mounted. The RX should / may have two antenna wires these must be arranged at 90° to each other and one vertical, one horizontal. Cheers Doug 😎

Twin Motor Perkassa by Dave M Fleet Admiral!   Posted: 1 month ago
I attach some pics of my 34" Perkassa. It uses two large water cooled brushed motors (650?). Two Mtronic 25amp ESCs with one red wire disconnected. You can see the ESCs on off switches over the former in the next to last pic. Presently has a Planet Tx/rx and I use 9.6v or 8.4v NiMhs of 3 to 5 amps. Not fused (naughty). The battery sits between the prop shafts towards the stern in a tray. I control the motors on the left and right sticks with the rudder on the right horiz stick. The left stick has a ratchet so I set the speed with that and use the right sticks to keep straight and steer. As an ex flyer this is an easy set up for me. Run time is about 10/15 mins but that's long enough for me and the other models on the lake!

Motor problem by pmdevlin Fleet Admiral!   Posted: 1 month ago
the good news is, (I should have mentioned this earlier), the contributors here are generally experienced, and have done it themselves, so rest assured everything you get is proven, you just need to pick out what is best for you. Some other forums are not as lucky, as you get a lot of "do this, try this", you go out spending the dosh, and the "advisor" when challenged has not actually done it himself, its just a load of crap.😡 really annoys me that this happens, and sometimes people on model shops can be just as bad. A mate of mine took his sons "toy" boat to a local model shop last year. His son had outgrown it, my mate wanted to paint it, make it his own, and ditch the "toys r us" running gear. I didn't know he had done this, when I saw what had been done, the money charged, we marched back to the shop, I gave the "expert" the crap back, and got a refund. 2nd hand 27mg 2 channel rx with the aerial chopped to 6 inches, a 4x1.5 aa battery holder for main propulsion, and a really tired 2 channel acoms 27mg tx £75😡 I found out when he asked me why the lights don't work from the tx like my boats, he had asked for this, 2 channel set, hmm.... later that month, with a 7.2v nims and a dx6 with now 6 channels, less than £50, experts eh! I know there are good, but this shop or at least the guy working there wasn't one of them

Twin motor control problem by John Fleet Admiral!   Posted: 1 month ago
Hi Dave and Paul, as the two current esc’s are new under warranty and came fitted with Tamiya connectors. I am reluctant to cut the wires for now hence the connectors. The switches are one from each ESC one of which has the red wire cut. The range test was fine so the tx and rx are fine. The rx goes at the front under the deck far away from everything and above the waterline when it sinks in full reverse. The wires were out so you could see how everything is connected. If this does not work I can try two batteries next.

I've breezed through this so apologies if I missed something. There is no way the boat will magically go into reverse when transporting from the bench to the water. If it works on the bench, it will work in the water, out of interest, how do you know its going the right way on the bench? you might have the props on the wrong way around if directional, so its actually going in reverse on the bench. You can run multiple motors with one spectrum receiver, I have done it several times, with boats and planes, so its not that. Your later posts suggest more is amiss here, it could be a signal issue, as you say it sometimes works? Have you done a range test? If you have not, This needs to be the very next job you do. Not knowing specificallky what tx you have, eg the dx6i has a built in range test, and needs to be done from all angles, and should work at least 20 metres from the boat. This needs to be a must on all models. I do this every time I sail or fly, every time, I don't want to lose a model due to signal loss, which depending on the failsafe being set, can result in full throttle and loss of control, that's another topic I suppose! Mtrokiks are pretty much bullet proof, forget those Chinese blue things, the issue isn't the escs, its the set up. Get the mixer out, use a "y" lead between the receiver leads, disconnect both red wires, and use a separate receiver 6v feed into the receiver, plug in the esc's, watch the lights to see if they set ok (assuming you have throttle range set them separate first), then range check, nw throttle on the bench, one at a time, with a tissue behind the prop to ensure they are going the correct way, belive me when I say its an easy mistake to make thinking a twin set up has both props with the correct direction when one isn't!😊 I see you are at Bury, thats a big well established club, has anybody there taken a look for you, seeing it in action is so much easier than over a keyboard! If you fancy a trip to the Wirral Ill gladly sort it for you Paul

Twin motor control problem by John Fleet Admiral!   Posted: 1 month ago
I will take some pictures when I go on Wednesday. The connections are all good. The problem is present either when the boat is first put into the water or shortly within seconds after. The battery is a 3cell Lipo always fully charged before use. I have used a bec and without a bec. Esc's are Mtroniks tio marine 30. I have tried several tx and rx it is currently a Planet!

Twin motor control problem by RNinMunich Fleet Admiral!   Posted: 1 month ago
Hi John, can you please define 'sometimes' more precisely ? For example; At the beginning of a run yes? -> After some minutes running no? Or right from the start sometimes yes, sometimes not? Under what circumstances do you have no control? What is the current setup? TX and RX make & model? Motors? ESCs, still Vipers, TIO version? BEC or not? Power source? Charge status? Re Dave's comment: can only highly recommend the exclusive use of gold connectors only (regardless of type) between ESC and motor. And on the battery as well.

Titan by wunwinglo Chief Petty Officer   Posted: 1 month ago
I don't think that Her Majesty understood the principle of R/C. If you look carefully, you can see that she is the lady in the pale longish coat facing right. I think that she is holding the button box of a typical ground-based TX. She almost has her back to the model......My father worked as a scientist there and met many dignatories. His POW - learned German meant that he took Willi Brandt round the site on one occasion.

Twin motor control problem by Dave M Fleet Admiral!   Posted: 1 month ago
John From all the info I do not believe the answer lies with the ESC. When you run on the bench you are viewing both motors and they rotate in both directions as you move the Tx sticks to both extreems. When you run in the water you are viewing both motors and they rotate in one direction only as you move the Tx sticks to both extreems. Can you confirm this is the case, please.

Twin motor control problem by John Fleet Admiral!   Posted: 1 month ago
The problem is both motors. For some reason they work fine until they are in the water then they both only go in reverse. It is not the transmitter as I have tried two tx and rx. Not about distance or height. Nothing is connected to the water. Have tried moving the rx. Current thinking is it must be some kind of feedback between the ESC's but that does not explain why it does not do it on the bench.
