RE: GWS Servos
I have been using the smaller GWS servos with no problems so far but I don't think I would put them in a high stress application which is what metal gears says to me.
I can't say there is anything wrong wtih them. No failures, nor issues, but they just give me impression of not being as strong as the Hitec servos, which is the other brand I use. I run HS-81 MGs in the wings of my full house sailplane with good results. Flaps take a beating. So far not problems with the HS-81s.
