RE: Ebay / hong kong heli's, the good / bad / ugly?
If your looking for a little larger sport flier the quick would fit the bill.For 450 size the dragonus would be the best and capable of any 3d move.
But here's the rub.All the components that come with all those helis are very low end.The servos in the dragonus you can buy for $3.50 retail a piece.The helis are not factory assembled.Probably put together by a kid sitting in a stock room.So disassembly required.
All in all though the prices are very cheap and the components would get you in the air.But you would want to start upgrading once you get beyond hovering and a little ff.
