I know the people here aren't interested in toy copters like this, but i was hoping to get an answer and didn't know where else to turn. Can anyone tell me how consistant or inconsistant these are from one example to the next in how controllable they are? The reason i ask is that i have a friend with one and he told me it was somewhat hard to control. then it went bad a week or so after he got it and he took it back to RS and exchanged it for a new one which he says is far more controlable.

I intended to buy one online because they're about 1/2 the cost that RS charges. But i worry that if they are very inconsistant as far as how controllable they are from one to the next, buying online might end up being more trouble than it's worth and maybe even costing as much if i have to excahnge it a couple times due to shipping costs. Thanks.
