Alrighty, im terrible with all this electronic stuff so I figured i'd ask here.

what i've got:

Kopropo ex1 mars
Ace 1015 servos

So, two things;

1) For whatever reason, my throttle servo is running backwards, when I hit the throttle, its making the brake rotation, and when i hit brake it pulls on the throttle.

2) I'd like a walkthrough on setting the trim or whatever its called on my servos, so that I dont burn them out or break any parts.

Thanks in advance for any advice!

Do you have a manual? If so; I would take the time to read it. You just need to reverse your throttle channel. This can be done thru the radio.

yeah my radios pretty old schoo, I dont have any of my old manuals anymore >.> I might just go buy an ex1 UR, idk

HERES your manual buddy. Read it! It'll do ya a world of good.

yeah I stayed up all night and read it figured out the reverse thing, still dont have a clue about trim or how it works, more research for me!

EPA or Endpoints is what you are looking for, these control how far a servo can travel in one direction.

Trim and Subtrim are used to center the servo. Use subtrim first as it doesn't not affect total throw.

nice, thats exactly what I needed. thanks a million MikeXRAY
