Okay, so got the kit, and a Taigen KV1 metal chassis. I have the top and bottom hulls fitted together by dremel work on the rear to narrow the top hull enough to allow for the extra thickness of the aluminum. So after placing test gearboxes in place, I cannot get the top hull over the rear of the gearboxes. Should I just flex it over? or??
I'm thinking of cutting the rear, lower portion off, and screwing it to the chassis to stiffen it, and avoid the interference with the gear boxes.

thanks for any help, Jerry
