all you tamiya f103 guys

[gerbil]

hi ive decieded to keep my f103 as i enjoyed it to much
how ever i have a question with the batterys having to go across the chassis the holder is slightly to small by about 5mm what do you guys do as i have to stretch them and some times it drags on the ground ??
sorry if the question doesnt make sense ill try to get pics up tomorrow to explain better
any advice is welcome
