Thanks Ed, I am going to take everyone's advice and leave my IR gun at the house. I've got it set now to take off from about a 15 foot run using an 11X7 prop. It will pull vertical till you can't see it anymore and will stay up for more than 15 minutes on 8 ounces of fuel. I do not know what people are doing to get close to 14,500 RPM's out of this engine, but I was unsucessful using the same 10X6 MAS wood prop, 15% Wildcat Extra and an OS A-3 glow plug, all I could get was 13,300 RPM. My hat is off and I am humbled by you w8ye! By the way, I am turning 11,400 with a 11X7 ASP, 12,900 with a 11X5 Nexstar Select all on 15% Wildcat Extra, I didn't get the chance to try the 11X6.
