Well, I must say that this is an expensive hobby. Not sure why such an addiction but I just keep at it. My helipro was given to me by my wife as a birthday present.Not knowing what she had bought really because I had never flown before but yet she got me the 6CH CNC everything model. I started out very catious only appliying enough throttle to get it light, then got bored and tried to fly it. As you could of guessed I crashed and it has never been right since. I replaced the damaged parts, spindle shaft, fly bar and couple ball links, and was able to get some flight time in. I can now tail hover and working on my nose hover. The heli has since developed this sputter once I gave it throttle, making it impossible for me to hover. I suspected the ESC and the radio and TX, replaced all without luck. It is still sputtering and the only thing left is the motor. I will replace it as soon as I get a chance. Anyone have an idea what motor I should get?

Does this count for the nitro edition too? haha

One thing I ran into was the oneway bearing sleeve was loose in the gear causing it to spin up, but once any load was on it, it wouldn't stay engaged as the bearing was just spinning around inside the gear. CA'ed the outside of the bearing into the gear and it flies fine.

It acted as though it didn't have enough power to lift off and I, too suspected the electrics. Worth a look I guess.
