Did you have one fail during testing?
Yes, thats what I wrote above. It failed while we were still centering the aileron. Actually it jammed completely. We opened it up to check whether any gears were in bind but that was not the case, the pot itself had failed and there was not much to do about it. I had bought 6 in all to use in various places on the monoplane and we ended up using none, so I have 5 spare. It will actually cost more than the servo itself if we have to claim returns from Tower, so we didnt do that

The cost of the plane doesn't have anything to do with it.

What does is the size of the control surfaces and HOW you set up the linkages.

Make sure you go for MAXIMUM MECHANICAL ADVANTAGE.


I've used one of the 225MG servos to control FOUR ailerons on .40 sized Ultimate biplanes.

The servo drives both lower ailerons which in turn drive the upper.

This has worked just fine for me on three such planes and I'm pretty certain my little 225MG's are overcoming far more force than they would see on the Reactor Bipe.
Ok, how do you really check whether a given set of servos are reliable? Is the servo test feature on the TX the right way? And if so, how long continuously should I run this feature for testing the servos


ORIGINAL: opjose

Just remember NOT to but the control surfaces right up against the wing edge... make sure you leave a small gap so the surfaces can move up and down cleanly w/o binding.

All too often people get so hung up about hinge gaps that they forget to leave ANY gap, which is equally important.

Ok I will take care of that
