Servos installed in 2m Glider
Comments:
When setting up the servos in the wings, I had two servos fail. One Aileron and one Flap servo. The Aileron servo jammed solid, probably gears, and the Flap servo tatally burned out, melting the servo case and servo lead. I am running 6v electrics, has anybody else had the same problems? I have used Corona receivers for a couple of years without any problems.

it is very good servo as long as you are not using it on 6V. I have heard about strenge situations wen it was used on 6V. I am using it on 5V and there is no problem with at all.

EP Airplane & 450 Heli
Comments:
I have been using the CORONA 939MG on my 450 Cyclic and all over my Dynam T-28 Trojan control surfaces for over a year now.
So far non has failed on all my applications. It is powered by a Turnigy 5Amp UBEC on 5volts.
The gears are a bit noisy at times specially when binding occurs, its actually a good sign because it lets you know about the bind and or excessive loads.
Weighs a little more than most plastic 9g servos but gears are more reliable on any application.
I recommend this for light aircrafts with light to medium loads. Its a bit slow for 450 heli cyclics but does the job anyway.
