micro servo question

       Remove this ad - become a site supporter!
Maybe someone has asked this before but cant find it.

I have a plane which the throtle was setup with a hitech hs 81 micro. Its screwed in near the fire wall. The servos were not included with the plane but i want to go with what they had setup before. I have bought the hs81 but am wondering if there is something different you have to setup on the radio as the micros wouldnt have the same travel as a standard size servo. I havent used micros in anything before and wondering about endpoints and such...

I am running a futaba 9c.

If someone could point me in the right direction that would be great.
Its great when your 3 year old knows the names of all your planes lol

Ditto . That was my first thought as well....

The longer the arm, the more load on the servo. But since this is a throttle servo, the longer arm shouldn't put too much of a strain on the servo.

From a standard servo arm, locate the position that you would normally install the throttle push-rod. Measure the distance from the center of the servo arm to that point, then get a servo arm that will fit your micro that has the same dimension. If you cant find a one-piece servo arm for you micro that will get the same dimension, then you can screw another piece of servo arm to the existing servo arm to make your own extension. Bind with dental floss and CA the joint and you are good to go.
