I'm not sure what to check. I ran my truck today and got it dialed in nice to the point where its almost pulling wheelies. but when taking off ,the truck pulls to one side as if one wheel is getting more power than the other. I played with the steering trim and improved it a little but still wont go straight at higher speeds .If I throttle it while holding on to the bumper they seem to all have equal power enough to all spin against the resistance . now my stock wheel hexes arent that great anymore . I just got all my parts in to do the steering upgrade and I have a brand new set of maxx wheels that arent glued yet. does this sound like steering\wheel spinning problems or DIff problems.
