RE: Getting tired of wearing-out servos
I had yet another one go bad, this time on the elevator.
Like the others, it progressively lost its ability to center and was doing a little "Flutter" at rest as the engine was started. It became pretty bad on Friday evening's last flight(Would not settle down until about 1/3 stick travel) . I got lucky as It was not enough to cause anything serious, just enough to ground the plane until it's replaced. This one also lasted a little over 3 gallons.
I like the "Tubing Bushing" idea. Lately, I have been using 1/2 grommets but I was not entirely satisfied with the solutions as the screw's head was still in direct contact with the casing.
I looked around and saw the HS56 and HS65HB (Like Mr Cox says). The guy at my LHS says the HS65HB is also significantly thougher (Indirect pot) and he's never worn one out. I'll try it and see.
