My elevation is 4800'
DA w/ NX22x8 (15 min run time on new engine) 6690 RPM = +/- 21 lbs thrust
EVO w/ NX218 (2 gal thruough it) 6750 RPM = +/- 19lbs thrust.
Actually, those are pretty respectable for 4800 feet
I'd like both engines to spin up to 7000 RPM if I can. The EVO flys the Cap very nicely but I still think there's some more thrust in there somewhere. Anyways, I like to try a prop change and see. Too bad the 21x8 won't go over on the DA for a try (drill pattern is different).
I have done this going from a DA bolt pattern (4 bolt) to a 3W bolt pattern (6 bolt) but I do not think you could go the other way, It would be nice so you could test it.
I'll order a PT from TBM. Like I've said before...I'm brand new to the gas thing. Still learning.
Thanks for all your advice. I respect your opinion.
It does take some time to learn all the little things, just like when you started in glow, but once you see "the pattern" it gets tons easier. When I was learning to tune the needles, I praticed on my weed eater. Now I have the best running weed eater around
I appreciate the repect
