Hi David,

I just got home from the hobby shop. They only had 15% Powermaster with 18% oil in stock. I have the 1" rise header. The OS #8 plug is too hot. That is the plug we ran in helicopters with 30% nitro fuel. The OS #5 is much colder. If it will do 16k on the ground with the stock uncut header it will be way too fast for my advanced years to keep up with. I will snap some pics today and get them posted. I will shoot some pics and video tomorrow when I test run the engine and again on Monday when I test fly the plane assuming the weather doesn't suck here in central NC. I may have to drive to Raleigh on Monday for the test flight if their weather is better.
