I managed to get to the hangar after all and started roughing out the AL prototype. Should have a flyable version on Tuesday. I have a 4 pipe exhaust so will be different than others. Also looking up the lower cowl, I have a very restricted and cluttered outlet. 4 pipes, engine breather tube, exhaust hangars and heat muff in a opening smaller than factory cowl....I've got work to do.
Sorry about the lousy cell pic.
