Well...I think I got this HBKII tuned as good as I can get it. Stability is great, the brushless and ESC are flawless with good power. The auto rotation works as advertised...that was COOL! MAN this heli is just perfect. I'm now eyeballing the HoneyBee Cool, it's shaft drive tail, but that won't be for a while. Anything with a 3-1 or 4-1 and electric tail....forget it. I'll never go back. I've had countless flights and the motor/ESC barely offer to get warm. Motor replacement...if it keeps up like this it'll be a long time before I have to buy another motor. Barring crashes....I'll just be flying this thing it seems. I've heard the gyro might be an issue but if I have to, I'll throw a G90 on it because it's worth the upgrade.
