The plane will fly slower than my GWS Tiger Moth. It is all throttle management. Make the leap, the rewards are well worth it. I have only had about 5 flights on my set up ( (300 with the 6.6 to 1 gearbox and a Thenderpower 2 cell 2100 mah) and am very pleased with the flight performance. The vertical is ulimited almost right to the battery cut off point of my speed controller. The pack is light and does not heat very much at all all after a full flight. MAD out.
