I hope to get a hold of a mejzlik 22-10 to get a thrust measurement. I think DA has this engine pretty well figured out!~) I agree Dick, 7300 on a 22-10 mej is pretty good. Not sure mine will do that without leaning the heck out of it, which I won't do. I'm really getting into the way my plane flys with the DA/pipe combo. I've gotten good feedback from some great pilots that have flown it and say it flys like a much bigger plane. The range of planes that this engine will fly is awesome. Now if I could get a DHmodels one off pattern design for this combo!!~) THe impact from comp-arf might come in around 11lbs and be fun. THats what Jasons weights with lipolys. Hmmmmmm. My digital scale will be here this next week so I can compare against my friends. BTW, I use 2 different tachs to get my readings.
I bet that edge is a fun plane!
