View Full Version : Can't use push/pull with Ace Servo Arms

Hi everybody. We were looking at my Hurrican 50 at the field and checking out the fact that the push/pull links bind at both ends of the travel.

We pulled one end of one link off, and set the servo at extreme travel, and the link hole was not even close to center on the ball. We did this with all 3 cyclic servos, with the same results.

We were scratching our heads as to why it was so off. Then later one of the guys found the answer (good job Tom!) - the servo arms on the ACE servos are not symmetric!!! :dontknow

All 3 holes on one side are at a different distance from center than the holes on the other side!

What's up with that ACE!!! :!: :!:

Anyway, had to remove one link on each servo since you can't run push/pull with these arms. Bummer.

Rock,

I don't use Ace servo's but, do they offer a large wheel like I get with my Futaba's, then you can use a servo alignment tool and drill your holes where you need them :lol: there is always a way to make it work.

Have you tried Dubro, I thought they made arms that would fit most of the brands, I use them on Hi-tech and Futaba

Which ones - the universal or the Du Bros?

For the Du Bros, need to find out if the ACEs are compatable with JR or Futaba.

And no, they did not come with any wheels. Only the one nice, but non-symmetrical arm. Now I wish it did come with a wheel.

The Ace servo arms have the holes on one side "even" for example 10mm , 12mm , 14mm and the other side "odd" 11mm , 13mm , 15mm , ect.
if for example you wanted 12mm pull-pull just drill a hole between 11 and 13 on the odd side
