RE: No Traction with body fixed.
The car is very low on the ground.Scale 1/10.The only other thing I can think is that the engine is a pullstart.I have three open holes on the body.One on the front windscreen,one atthe bacl for hot air to be released and then I have made a hole on top of the roof to pullstart the car otherwise whn the car is idling I still need to put the body on and put the body clips in and then sometimes the car dies and I have to do the whole process over again.So,I think the possiblity is that the hole in the roof is probably casusing the proble.I dont know if it is creating an so called air bubble at the back thats why the car looses tracktion.
