Well, more question, I just started to run in a track. I ran at 8feet wide track and it has 180 degree turn. The HB Stadium Pro just couldn't turn within the track. I use Futaba s9451 for steering servo. I set the end point where inner wheel is slightly touch push rod. I need to spin the rear wheel to turn and stay in the track. Is this normal to most traggies or my set up is not right? Thanks!
