Ha about 2/3rds of the plane is fuel proofed. I found an additional problem with the tank though. When I put the canopy on it would tilt the tank forward rubbing the fuel line on the hole in the engine mount. I used the dremel and added a notch to the hole so the bottom line has plenty of clearance. It needs to be ready tomorrow. I have a fella with a lil toni and a midget mustang goin up with me. If the thing runs with no glitches I should have them. The toni has a 1.08 OS and was faster than my minnow but at probably a pound lighter the downer should take em out. Oh and the mustang is running a Evo 61. The ol downer better do me proud. But I still cant wait to get my new minnow built with the YS 110.
