Default New Tornado S30 Owner Needs Help



Recently purchased my first RC car for my son and my self. Question is, during break in period I noticed my car "pulled" to one side as i was driving. later when cleaning it I noticed that when I turn both the rear wheels only one front wheel turned. Causes, soultions? Thanks

when you turn 1 rear wheel...the other one should turn alittle in the opposite direction.

You could have a broken dogbone (driveshaft) but if that were the case then the rear wouldnt get any real power from the motor as the diff is open(and power will go to the side with no driveshaft)

Have you checked the steering trim on your radio?

No I have not checked the steering trim, but I will. its when I turn both back wheels at once only one front wheel turns, the other acts like it wants to, kinda "bumps" if that makes any sense, but like you said if I turn one front wheel the other goes opposite, same for the rear.

Thanks

Have you checked to see if the dog bone is in the one wheel that does not turn? If you turn the one front wheel that does not turn does the other front wheel turn?

OK, sounds like your drivetrain is fine. the diffs are open, so if you turn both rear, then power will go to the front and turn the tire thats easiest to turn.

My guess is that either 1 wheel has some binding or the steering trim is off.

See if adjusting the steering trim helps...

and turn each wheel by hand and see if any of them is harder to turn.

On a tamiya buggy I had, you could over-tighten the wheel nut and make the wheel just alittle hard to turn. I would have to tighten the nut all the way, then back off 1/2 turn.

My Tornado is like this. If you crank the wheels down they will bind. Also a steering issue I had was over-tightening the lock nut that holds the screws into the steering knuckles. These are the screws that hold the steering knuckle to the control arms. If the lock nut is too tight, the steering will bind.
