servo selections

[Atwood, Mark]

Excellent advice regarding the throttle servo.  MANY times I've seen throttle problems, or just frustrating idles be the result of using the cheapest servo in the shop, and often a cheap mini servo to try and control the idle of 4-stroke that's vibrating all over the place.

I'm also an advocate of simply a good quality coreless ball bearing servo.  In my case, Airtronics...that's a 94731 or 94735.  The staple servo for just about everything, though I'd be lying if I said I haven't begun to enjoy the snappy response that digitals (94758's) give me on ailerons.  But everywhere else I use the coreless analogs.

Futaba 9202 is a good all around value. You are a pretty good flyer if you
can tell the difference with a more expensive servo. I will probably not
spend the extra $$ in the future for the skinny servos in the wings either.
If there is an advantage there, my skills cannot exploit it. Avoid using a
cheap servo on the throttle. I have seen a lot of engine fiddling due to a
crappy throttle servo. There is no way you can achieve a reliable idle if
the servo is flakey.
