ok i messed up with the roll bar in the kit. and now im missing a big piece of it. so im thinking of using the sprue tree for making a new one. 1st thing i did was chop it up some to insert. so straw tubing so it looks like its got some padding on it. any other ideas or tips would be helpful. note; also how do you guys make rear spoliers, parachutes,and wheely bars any way?
