RE: H9 60 Size P-47 Thunderbolt-Build & Flying
BIRMAN,
Look inside the fuse at the backing on your firewall. Mine was in the shape of a plus sign, and was designed to add reinforcement to the mounting holes only. I also mounted my Saito 100 inverted, but when I drilled out the mounting holes, discovered they didn't go through the reinforced part of the firewall. I installed some additional plywood in those empty spaces, and everything worked out fine. It was definitely worth the trouble for strength, and I cannot understand why anyone would leave the engine sticking out if there was any possibility of avoiding it. I would much rather alter my engine preference to keep things under the cowl. Also, no problems with siphoning using a 3 line setup.
