could someone give me detailed instructions on how to make my own mounts. everyone says aluminium but it's flat!!! If I screw it in the screw has nothing to hold on to and my platform of the chassis is made from those cd cases that come in the mail the aol ones. Maybe I should change my chassis but still the holes on the servo??THe screws won't hold the aluminium and if i get like a block of aluminium i cant make a hole and i don't have a drill. Help!!
