Only flown the N22 never found it to be dangerous but definitely not the easiest or nicest type I've flown.
Take off rotation technique was interesting, to get the thing to rotate one needed to pull the control column back into your stomach until the nose started to lift and then check forward to stop over rotating. Not an aeroplane that would fly itself off the ground.
The nomad wins the prize for the hottest type I’ve flown. The ventilation system if you could call it that was as good as useless. The military POH we had a copy of set crew flight time limits based on the OAT.
The only way to get rated torque from the engines during the power check after maintenance was to do the check with the generators turned off. GAF AFM torque figures were higher than the torque figures in the Allison engine manual? Full torque was not available over 20 deg c.
The crew doors leaked in the rain. Problem was the avionics are located under the pilot’s seats. Easier to seal the floor so the avionics wouldn’t get wet and bail it out like a boat than seal the doors.
The flap/aileron/spoiler system was an engineering marvel consisting of bell cranks push rods and bungie cords. Flap 40 landing distance was impressive even though the brakes were not.
