Newbie needs advice about ESC's

[Wax Savage]

The brushless motors in my R&R WTC are rated by the manufacturer at a max 11-amp draw. To save space in the WTC can I safely use an ESC rated at 12-amps? Lastly, do I need to a use bidirectional rated ESC to go forward and reverse?

Thanks for the help...

I would go with 20A just in case, but if you keep the throttle low and run at scale speed, 12A should be okay. Yes you will need a bidirectional ESC, preferably the type without the neutral brake function.

I have no idea where they got 11A from, but that must be a full stall state. In practical application, at full tilt, the R&R motors draw no more than 5A with a 1.25" prop.

Over speccing an esc isn’t a bad idea, submarines by their nature tend to pick up weeds and other muck around their props that can load up the motor beyond its normal running amperage, and the difference in price between say a 10a and 20a esc is trivial these days.

I wasn't suggesting he grab a 5A ESC, I was just trying to mitigate some angst about massive current draw on the motors. I run 12A ESCs with these motors with zero issues.
