Looks good, you may need a rudder if you have problems turning! I had a similar boat which was fine in straight lines ๐

I always use a grub screw to lock my propellors where possible. I have lost a few myself mostly when using reverse.

I was just nice to see her sail Dave. it was very quiet at Bury today, I guess a lot of people thought the lake would be frozen with the early frost we had.

Hi Doug, I am running late tonight due to my list of jobs! The problem is solved! I still do not understand what the problem was but the replacement of the escs has done the trick and she now performs as she should! Sailing today was a real pleasure thanks everyone for your help.

๐ Twin motor control problem
7 years ago by
๐ฌ๐ง John2 (

Hi Dave and Paul, as the two current escโs 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.

Hi Paul, yes the easy solution would be to get a single esc to power both the 600 motors. I am going to look into that option if it does not work this week ๐

Hi Paul, yes it sails at Bury and I am continuing to try different options. There has been much head scratching at Bury over the problem and the rescue boat has been out a couple of times to rescue the boat in reverse. The Y leads have been tried as you suggested. it is easy to test the rotation direction by feeling the air flow and slowing them manually to observe them.

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!

That is a very interesting question Doug! and the answer is yes and no. Sometimes I have control of the speed on other occasions it has gone to full speed reverse and I have no control.

Hi Dave, yes on the bench everything works as it should in both directions. in the water the only direction is reverse. Sometime it can go forward at low speeds for a short period before the reverse kicks in but then only reverse is available at all speeds.

No voltage on the prop shafts of rudders, it must somehow be related to the increase in the current being drawn when the motors are under load. That is why I was thinking try another type of esc which does not required any setting up. I will let you know what happens Wednesday ๐

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.

Sorry Reilly, A single motor with one ESC works perfect, as does the other motor with the other ESC. The Viper ESC's have been set up as a pair in the boat and individually on the bench. The problem remains only when the boat is in the water. So I am going to try ESCโs which do not require any set up and see next week.

Another week and the problem remains despite trying different options. Plan is to buy two new ESC which do not require programming or setting up. The good old blue metal ones! Will let you know what happens of course.
