Ibought a E-flite deuces wild twin airplane, its been loaded with 2 unknown/unmarked speed controllers.. Ineed to program the throttle endpoints on both of them, as one is stronger than the other. which on a twin is a bad thing.



Ican open one of the esc's Isuppose, but Ireally would rather not.

any help?

They appear to be Mystery Esc's. I prefer to do each esc by itself for throttle endpoints. Basic proceedure is same for almost all esc's.
Remove props, unplug one esc, turnon radio, throttle to full, plug in battery, wheen it beeps (usually twice) pull throttle to idle, it should beep again, then pause, then either beep the number of cells or music to show its armed. Repeat on othere esc. Thats how I do it, flytreetimes

flytreetimes is right on the throttle range settings. Also another possibility for an esc would be a Suppo. Looks identical to the 80 amp versions I have.
