It certainly is a challenge to fly. The rudder works totally differently to other heli sims. No more press pedal to turn, stop pressing when you are pointint the right way, even at low speeds the heli seems to have a great desire to turn back to its original course.
I have also crashed a couple of times in inexplicable fasion. Just suddenly lose all lift and cant pull out of it. Is this blade stall?
Great fun but I need to read the manual!
