HS-645MG servo acting goofy.

[KevMc]

Since I strriped the teeth off my stock servo after a few days I went ahead and picked up the HiTec HS-645MG at the LHS. I plugged it into the Losi reciever and checked it before I installed it and it seemed fine, growled a bit but figured it was OK. Made a mount for it and got ready to crawl, but when I turned the rig on the servo just sits there and twitches by itself and really doesn't respond to the transmitter. Bummer. Anyone run into this problem, maybe I just got a bad servo?

Might try to diagnose it...try a different servo....Also, i've done this, make sure it's pluged into correct place on RX...Are you using a differnt Transmitter, if a DX3R check frame rate. If all that fails might have fried something else...Can't hurt to try8) hope this helps

Thanks.
Unfortunately I don't have another servo on hand to try, but I can plug the stock one back in and it functions just fine (besides missing some teeth).
All the other radio gear is the stuff it came with.

Make sure your servo wire is not near your power wires or esc. When I put my 645 in when the wires were close to the esc it would twitch. move your wires around till it will stop your servo is probally just fine.

Make sure your connector going into your receiver is plugged in the right way.

x2 on this. It fits in both ways.

It's in the right way. I tried it the other way just for the heck of it and it doesn't do anything. ESC wires are plenty far away. I think I just need to return this servo.

Bring the servo and the whole rig into the hobby shop and let them check it out. It does sound like a bum servo, but ya never know it could be something else.

Yup, did that tonight and they hooked me up with a new servo. All is working good now"thumbsup"
Leave it to me to wind up with the one bad servo out of a thousand.
Thanks for the help.
