June 25, 2006, today was the maiden voyage for the chipmunk and 91-cd (it is a used plane new motor but maiden voyage for me), after practicing some taxiing and some speed burst runs I was finally ready, the plane ways approx 8lbs on a bathroom scale and the motor had more than enough power, she took off at just over a 1/3 throttle and climbed out nicely, at just under half throttle she had lots of jam, I only flew for about 5 min or so due to the aircraft wanting to bank to the right hard, but during that time at just under half throttle she was able to climb perfectly, I am assuming under full throttle she will have unlimited vertical, engine noise was a minimum extremely quite, at an 1/8 throttle she came in beautifully. Will post more when trims have been readjusted.
