I can see where someone might be tempted to buy one of these after watching the video. All the problems I have read here sure don't add up to how the one in the video flies. Blade CX or CX2 are proven coaxials so next time spend the 200 bucks or get one from Hobby Mart on Ebay if its RTF and not having faulty parts. I got a couple CXs from them and they were like brand new but USED for like 115 bucks.
Dont let your problems with the hoverflash discourage your wanting to fly a heli. Its a great hobby and very addictive once you have experienced a good flight or two.
