Hello Miklos,
Thank you for the kind complement. The P-61 now has six flights on it and is pretty well dialed in. No issues with vibration which is a benefit of running balanced props and electric motors. I flew the "Lovely Lady" last weekend in some pretty gusty cross winds but it grooved along well. Needless to say, I am happy with its performance.
Flight times are over seven minutes on the two 5 Amp hour batteries with about 2/3 of the battery capacity used.
