I'm building a quadcopter and controlling the esc's with an arduino, I cannot get all my esc's to run with equal power. It seems one is working fine but all others max out around 50%. If I raise the throttle higher then 50 it will follow the correct power for a second then decrease back down to 50, any help? Thanks

possibly your battery can't supply enough current and one ESC has different LVC settings to the rest, hence it continues to rev up.

It's myfirstdrone**** and then you click on how to build a drone.

So I ordered everything, and I didn't think this would matter, but here is the question: Will these work with the NTM 28 motor? The NTM 28 motor is a 25A. I saw this configuration off of this site: myfirstdrone****/build-your-first-quad/. Please answer quick, as I need a fast answer.

Depends on your prop size and pitch. Hard to know how much current your setup will draw until you try it. If your Props are undersized for that motor you may get away with it. Always better to have a higher rated ESC than your motor though.

make sure your motor system wont exceed the amps limit of the esc or else you will fry it.
