Do yourself a favor and look into the Chaos helicopters. If you want to stick with clones, these are some of the best you can get. And, they are in the USA (can't remember where you are from) and their customer support is second to none. Lee has one of their helicopters and has had great luck with it. I would not do tarot or copterX simply because if you have a problem with it, you have to ship it back over seas just to have anything happen, if they put a warranty on it. Even if they do, you are still out almost hte cost of the kit just in postage.
