Well Volfy, The engine is mounted on a new firewall that is about a inch back from the existing one. My friend Paul did most of the work but it looked fairly easy. He just sawed of the sides of the motormount box on the front and top and cut a new firewall out of plywood to fit the front of what was left of the box. This was epoxied back on and reinforced from the back with glass cloth and epoxy. These planes are using the magneto that comes on the engine. Of course the flywheel has been thinned and lightened. The fuel tank is in the compartment where I believe the radio gear and battery go. It ends up just barely in front of the CG. Both planes are currently not flown but are ready to go when the weather and other obligations cooperate. They both have Master Airscrew 16x8 props, one a classic and the other a "K" series. The Ryobi is turning them around 7200 rpm so far on white gas with Stihl mix. One note: The cowlings would not fit over the flywheel without cutting when the engine is mounted at the firwall to drive washer length in the manual. Paul actually cut the top of the nose of the cowling off and made a new top out of glass cloth and epoxy then blended it in and repainted it. This was necessary to provide the clearance for the top of the flywheel to rotate without cutting or wearing a hole in the cowling. It only needed about a 1/4-3/8" or so. This was not a big deal either but then again Paul is a industrial modelist who builds prototypes for companies for a living. Handy friend to have, eh? The only other option would be to set the engine back more and try to find or have made a new propshaft adapter or go with the CH ignition. I guess it depends on your skills. We also contemplated not using the Jag motor mount and cutting a hole in the existing firewall for the carb to fit through and mounting the engine to the firewall with the backplate screws. I believe this would work as well but you would still have the problem with the flywheel. Brylee, the struts are obviously good because they faked you out. Paul made molds of the struts and actually cast them out of resin right around the factory gear wires. The shock shaft is chrome trim tape. They are nonfunctional and only for aesthetic purposes. Any other questions let me know and I'll take some pics of the pariculars and post them here. By the way I have two of the Hangar 9 scale WW II pilot figures for this plane for sale if anyone wants them. $13 each shipped. Maximus
