Hitec HS-81 servo problem, But total success with Ken Hill's "Polly Pusher"

First, everyone needs to know: the "Polly Pusher" from Ken Hill at Acesim is really good. I've made one, and I think it's about as good a speed 400 trainer as you could get--easy but fun to fly, fun to make, inexpensive, and tough as nails.

Now, if my HS-81 servos would just quit breaking down, I'd be in fat city--twice after medium hard landings, a servo has just stopped working. On autopsy, I find that the gears are undamaged, but the little circuit board inside the servo quickly gets hot when the radio is turned on. Any ideas on this one?

Everytime I bad mouthed the HS 81's here for the exact same problem you had (5 in a row), the only response I get is "they work fine for me". I know many people personally that have several of them in the junk box. I live near Hitec and took them in, they said they would repair them. I said I would never put another 81 in the air again and they could just keep them. I asked if I could maybe upgrade and if they could send me 2 HS225MG's for the 3 HS 81's I had with me (new project), I would be happy. Being the extraordinary company that they are, they sent me 3 225mg's. See if Hitec will work with you to upgrade to 85's, they are a great, dependable servo. Hitec is one of the best companys around for customer service.
