Yeah, it certainly is big. It's a side effect of the mounting of the actuator, if I ever make a Barróg 2, then it will almost certainly use a high torque motor system instead. I'm hopeful I can reduce the weight enough though while also keeping it at least somewhat sturdy. ALso I'm planning to run each sides motors in parallel, so an ESC will be shared on each side.

I'm not completely certain that my readings were accurate, but I measured the current draw of the LA with a multimeter, and I found it drew roughly 1.7-1.8A when in use, bursting to roughly 2.5-3A at the start of the connection. That sounds right to me considering that the no load current of the LA is .85A, and it's being overvolted. It certainly seems 30A is a little excessive: the issue for me though is if a brushed speed controller exists that A) is more cost efficient then the Botbitz ESC B) can take the 18.8V provided by the LA and C) can still take the current drawn by the LA.

If Jamie's solution can do the job though, then that'd be excellent, I have a few servos left over from my antweights that would do the job.
