Default *HS-5645MG Digitals, To Much Slop In Gears*

I have a lot of the Hitec HS-5645MG Digital servos and most of them have a lot of slop in the neutral position. I can grab the elevator or ailerons and move them a lot. This may be what is causing my planes to buffer up and down in flight. It hasn't caused any flutter yet but it makes me wonder when it will start. Anyone else have this issue? What have you done to solve this problem.

Buy new gears. MG servos are strong but tend to wear faster than nylon gears. You can also try rotating some of the gears a few teeth either way to even out some of the wear on them. Depending on how the output shaft is set up and the stops are set you can sometime rotate the output shaft 180 deg and have fresh gear teeth.

lrb75,

Thanks for the info. The gears shouldn't be worn out after less than 20 fights.

I have 4 of them and sloppy out of the box brand new, I also replaced the gear set @ $16 a pop and the slop is still there.
I buy the 5955tg only now for the larger stuff. I faced the fact I wasted $250+ for these sloppy servos. Could have had 3 5955tg for this price almost.
Hitec has a bad apple just like every one else, but they have a kick @$$ 5955tg.
I still buy hitec just not the 5645.

My experience!

I took mine apart and found that when it was assembled the center pin hole on the top case was forced in and not round createing a binding .[:'(][:'(][&o]

Zippi, a while back when I was shopping for good servos, I found that most of the "mid" grade servos aren't that good. I've pretty much accepted the fact that I have to spend a hundred bucks a servo.
