Ok, heres a pic of my gearbox. I never did paint it. I was going to. If and when you do this, make sure you rough up the outside a little so the resin would adhere better. I figured on this fix after loosing about three gearboxes in a short amount of time. Dont use the fiberglass cloth you get at the autoparts store. You have to use some finer cloth. Wrap the gearbox several times. This has been a real cost saver for me. Get an old tailboom and rub candle wax on the end or a fiberglass form release agent and insert that end in your gearbox. gives you something to hold on to when doing this. Im getting ready to do another gearbox. but going to add a plate to the gearbox so I can bolt my tailfins to the gearbox. Hey, this is fun.
