This weekend I flew mine since the repair job. It went back together just as straight as it was, and flies exactly the same. The 6" pitch prop is still the best bet, because it pulls at a lower rpm than the 4". It actually lunges forward with blip of the throttle. Cruising speed for this plane is about 1/3 throttle, and hovering is at about 1/2. It's so rediculously maneuverable that you can fly it in close and slow without much effort. I am beginning to get a little disappointed with the knife edge coupling issues. It wanders around so much that it's hard to find the right combination of speed, power and control inputs to get it right. I am told that the 90 size is the same way. Too bad, because it does everything else really well. I also found that 100% spoilerons mixed in helps stabilize the harrier, and makes walls a little less abrupt, making the model appear to slide a little more like the big ones do. Anyone who can't figure out how to flat spin this model needs to just go back and take some lessons on how to do it. She comes down at about 2 feet per second at about 1.5 revolutions per second with full power, full down elevator, neutral ailerons and somewhat less than full rudder. All you need to do to recover is neutralize rudder, then elevator, and fly away. Cool!
