XJet, I disagree with you about the pots. They DO have an effect on the centering of a servo. The pots in the lower end Hitec servosd are known to be poor quality. I guess thats why Hitec replaced the pots in the 645 servos I had. They wouldn't center and I sent them to Hitec for service. They all came back with new pots. Perhaps Hitec doesn't know how to service their own equipment?
You guys are all slamming JR about gear problems.
I've been running the same 8411 servos in a 50cc airframe for
4yrs and I haven't needed to replace the gears. They are as tight as the day I installed them--some 450 flights ago.
But, thats not the servo I recommended to him anyway. I recommended the 4721 coreless. Those are nylon gears and they don't wear out in a season. I've got about a dozen of those servos in various large models and have been flying them HARD. Not a single gear related problem from any of those servos in 3 or 4 yrs of flying in 50cc size planes.
I never said they were cheap. I just said they would
work.
