Hello Easystern, Thanks, Its been a fun build so far... I will be Breaking in the engine on the ground with a 11x11 Apc... Then I will Fly it with a 12x12 and see how it likes it and start from there... I will be glassing the Pipe to keep the heat down in the fuse. Ill get some special Header wrap and nicely wrap the pipe, it will run cool in the fuse.
