Digital Servos

I have them installed in a French WWI mono plane but have yet to fly them. When tested they appeared to work very well. I'll have a better feel for them after they've flown.

Freewing Servos

I have these servos in a couple of 40 size nitro planes. They work well and have never given a problem. I have them all mounted on rubber grommets to absorb the vibration.

freewing 17g digital metal servo

I tested the sevo when I got it, worked smoothly. The price was good. Quality seems good. Just installing now into my balsa built plane. One disapointment is the size of the servo mount tab hole. It is very large, like it needs a grommet and bushing. But none in the box. I don't want a rubber mount as I am electric powered. I had to make brass bushing to use small srews and get a tight fit. Is there some kind of bushing kit you are supposed to buy?

Replacement servo for P-38 Elevator

The original Elevator servo in my P-38 started jittering after many flights and I ordered another to replace it as a precaution. The new servo is operating smoothly and I feel confident that it will operate reliably for quite some time. I will be keeping a close eye on it though.
