Having a few problems with my proboat formula fastech

I have a Proboat Formula fastech, with (2) Venom 5000mah 40C LiPo's and a sharpened & balanced Octura x642 prop. The radio, ESC and motor are stock.

Problems
1. After I plug the ESC into the programming card (which seems to accept the data) and back into the reciever I have to unplug the batteries and plug them back in to get the boat to work.

2. After charging my batteries and programming the ESC and plugging everything in, I go to run my boat and sometimes it runs with no problems, but then other times power to the motor cuts in and out, but the steering never loses power, like i have a short somewhere. I just dont know if its in the motor, reciever, transmitter or what!!?? Please Help

Check solder connections

Yep, check your connections. a 642 is a big prop for that motor, the wires could be getting very hot and some unsoldering may have occurred.

Regarding #1, I believe that is typical behavior for this ESC. I've used a couple of proboat ESCs and I frequently need to completely remove power (turning the on/off switch isn't enough) to reset.

I have also had problems with connectors de-soldering when using x642 prop. X442 also works really well on this boat.

Thanks but the soldering was not the problem


@BHChieftain
So by disconnecting the batteries and connecting them back, is the esc still good with the data i set the card at and do i have to reprogram the esc everytime i use the boat even if i dont want to change any data or does it stay at the last setting i put it at

You don't have to program it every time.

Right, you don't need to reprogram the ESC after power is removed.
On your other problem-- how are the temps? Anything getting really hot? You also might want to try a different set of batteries-- maybe you have a cell that is hitting LVC. Try setting the LVC cutoff to low.
