Okay gang, el jefe is back with another round of questions. Todays topic:

SERVOS

Got the Savage 4.6 sorted out (after brief flywheel issue, thanks all who helped me diagnose!) and broken in and wheelying. One issue has got me baffled now.

I have a JR Z650M on throttle and one on steering as well. The problem is with the one on throttle. Everytime I go out for a run at the end of the day when I get home the 3x10 screw that secures the servo horn to the servo is missing!

I replace with a new screw and check for tightness and it stays put. I go out and run and when I bring it in the screw is missing. After a couple of times, I looked into the servo and sure enough the top portion of the threads are stripped. I find a replacement gear kit on JR's site: JRPSGZ650

$18 bucks ain't bad, but I'm interested in correcting the problem causing this so I don't have to do it again. Any ideas why that screw keeps leaving?

Also thinking about calling JR and seeing if they'll do me a solid.

Kid in Hobbytown told me that for the trouble it's worth it'd be better to buy another servo than that rebuild kit, LOL, my wallet says that a little elbow grease is worth it. Servo is barely used and not even a good month old, used even less time than that.
