3 inches or 3 foot whats the difference.Air is air .Trust me it pulled both of them off the ground evenly a few inches.Unless about 40 people were pulling my cord .I felt the front tires hit every time as well .No it didnt get on the bumper ,but thats not the slapper bars fault.I dont have the gears, stall, or motor for that kinda show ...
