RE: The complete YELLOW AIRCRAFT SPITFIRE thread.
Thanks Len and Brad. I posted a few pics below. The 3W-70 fit rather well into the nose with a little persuasion. The firewall former had to be released from it original placement in the fuse and set back about an inch or so in order to obtain the correct protusion of the driveshaft from the fusealge tip opening. Then I created a customized firewall to accomodate the engine. The muffler also worked out very nicely. I wish I could take full credit for it, but I "borrowed" the idea from Evan Quiros who did the same thing in his YA Spitfire. You can see the muffler placement in the pics, too. I also attached isolated pics of themuffler after I fabricated it.
