Thanks again for all the advice.
I made the following changes:
1) Added 1/4 oz. weight in the wingtip.
2) Moved the center of gravity to 1 1/8" aft of the leading edge.
3) Used an 8x5 prop cut to 7"
4) Used Wildcat super 1/2A fuel, 25% nitro, with extra
castor oil added.
5) Used 49' .012 lines.
Had no line tension problems and good power from the
engine. Now all I need to do is find a 2 oz. uniflow tank
which will fit, I'm using a standard vent tank now.
Saw an "interesting" incident while I was flying. I use the flying field used by the Chicagoland Circle Cutters, one guy from the club cut his finger on a spinning prop, pretty badly. His friends told him to go get stitches, he just said "I've done worse," wrapped his finger & hand with a rag, and continued to fly with this increasingly bloody rag on his hand. And I thought I was a fanatic for flying in January with 8 inches of snow on the ground.
