I have flown APCO since after leaving PM school. I had the Lift, force 2 and NRG XC. I recently tried the F1 and let me tell you, it’s something else. Faster than the NRG XC, specially on trimmers alone. But my biggest surprise was efficiency. I need less power to fly the F1 level than I need for the intermediate force 2, despite being from 10 to 20 kph faster! Takeoff and landings require skills (fast runs and precise flare required) but if you are a skilled pilot you can nail a standstill landing even at max recommended weight.
