Okay I saw the tach read 8640 rpm
it sounded okay after watching the video
I see why you have the big landing gear
at the end a pass or two before you landed it sound like the engine got a little ruff while running (rich setting)
other than that it looked and sounded okay
how is the vertical preformance I thinking pretty good
I see you are testing with the cowl and tunnel on
I left mine off for the first couple of test flights
I still am having a little problem with the engine setting on the top end
I think I am going to a 15/8 or 15/10 prop I was hitting over 10400 on the ground
repairs almost done
