So I took the kids to the track today my son was pulling sky wheelies at will! He had a 2s 30c 4000mah Lipo and slipper clutch is backed out a half turn from tight. I had my 2s 30c 5000mah, slipper completely tightened down, I couldn't pull a wheelie. My son also has team associated 9809 tires. So what is causing all the wheelies?
