That's a pretty cool article. Definitely worth (for me) spending some more time reading. So far I've only looked at linear systems.


I set up my Yak very carefully with respect to the control system. The aileron control arms are pretty much identical, and center points and one of the end points were perfect. However, one aileron would deflect slightly more than the other, in only one direction. I definitely am one to try a mechanical fix before turning to electronic 'crutches', however I couldn't seem to get all points matched up. The result was a plane that yawed substantially with right aileron input. My radio didn't have the ability to independently set dual aileron endpoints, so I got this servo programmer, and the problem was quickly solved. These were two brand new, identical servos (HiTec 7000 series).

Anyway the OP is not talking about programming servos (although he does mention that this unit is capable of doing so [which requires compatible servos]). There are other good functions that this unit does that can be beneficial to anyone, including beginners (in my opinion). I appreciate having a tool to check and center servos before installation, without the need of using my complete radio system. It is a good way to check those pre-owned servos that many of us come across.

Seems like the original questions were answered: check for broken gears by listening and feeling the servo horn during travel, applying light resistance if necessary. "Burning In" is a bit of slang (in this case) for checking the range and functionality of the servo.
