The combination is results in the smoothest running piston airplane most of us have ever experience, although we can t say whether it is the prop, the engine, or the combination that s responsible for the silky feel. We do intend to eventually try other propellers. With the big engine, the projected gross weight is 1750 lbs. The airplane weighs 1071, so there s a healthy 679 lbs of useful load enough that with full fuel, and two 180 lb. You ll have to put that extra 3 pounds up near the firewall .
Performance is good.
It takes several take-offs before you believe it that big wing takes over early and with all the power on tap, the 9A gets to flying speed in a hurry. The airplane jumped into the air. Cruise speeds have been the most pleasant surprise. The airplane turned 185-187 mph. Fifty five percent yielded 166 mph.
