what weight is your b4

[zoaman]

as title .i am struggling with rear grip have spent alot of time making adjustment(tweaking) but still have no rear traction.front is ok. mixed tyres and makes no difference.have added low rear weights but sometimes it makes it worse. running on carpet and vinyl floor indoors.carpet is ok but nothing on vinyl.turned the motor down to low and 65% on hand set. but just no traction.others in the class are like sheit to a blanket.so im wondering if im miles too lite.cheers
