Default HELP DNX408T

I have a problem with handling. I am fairly new to rc racing and I have recently bought a new dnx408t and had 2 race meets. my problem is everytime I give it a good amount of throttle it pulls to one side. it can go to the left or right. it makes it impossible to line up big jumps as I cant hit them going straight. also on the main straights it is just pulling to one side as soon I give it full acceleration forcing me to back off instantly. I have tried changing a few things but have had no luck at all

Yea that sounds like some bearings on the Rear hubs or diffs . Check them.

Or your steering trim is off on your radio .

its definitely not steering trim as will stay in a straight line until I give it a good amount of throttle. when it is only under say a quarter throttle it will stay straight but as soon as I give it say 3/4 throttle or more it hooks to either side

Something's definitely not right. Its unloading to one side causing the pulling.

Pull the front and rear diffs, make sure the internals gears aren't stripped. Make sure all of the 6 CVD pins/diff cups aren't worn and slipping. Make sure the wheel hex pins aren't broke.

Sounds like some bad bearings somewhere in the drivetrain also i know from a long time ago i heard that it could cause your truck or buggy pull to one side when on the throttle .

Turn the radio system on. With the servo at neutral (but powered on), try and physically turn the front wheels side-to-side by hand. You should feel resistance of the servo trying to center itself back out.

If you can easily move the wheels, then either the servo is too weak or your servo saver tension is set too loose.

If a wheel bearing was bad, it'd constantly pull to one side, not one or the other.

I'd guess it's either diffs or something in the steering.

What? I was commenting on the thread, as everyone was seeming to ignore the to either side part.

Exactly. Diffs or steering. Check your servo saver is tight. If it is loose, the car can wander.
