I haven't sent mine back yet. lol. Thx for reminding me. It's the gears for sure. They said no problem. Send back with copy of receipt. I have the 1210 in mine now. And works great. Very strong. I didn't install a
bec or anything. Only thing I notice is sometimes when sitting still if I turn wheel and release if will still make a electronic sound like it's still working when goes back to center. But if you tap steering or throttle it stops. Only time I've noticed it is when changing batteries or working in it. Seems flawless when out playing thou.
Also I have a tbone bumper and a rpm one. Ordered rpm when tbone was taking so long to get here. I ended up installing the rpm one, as I like having old pin holing area from factory left on and then this one goes on in front of all that.
