Anyone having problems with the H9 fuel tanks?
Ultra Stick .40 - Reinforce the firewall with tri-stock and pin it through the fuse sides. Reinforce the landing gear mounting plate. Toss the metal gear mounting hardware & mount it with 1/4 x 20 nylon bolts & tee nuts. Toss the engine mount & replace with a Dave Brown or something similar. Reglue all the glue joints you can get to. Cheers
