same as this one, probably the same brand re-packaged

it uses a similar battery type except it has a connector instead of two rails and comes with a cord to use a usb port for charging. If you break all these helicopters down, take off the shell, they almost look identical but the transmitter for the Nine Eagles/Revell is much better; it has dual rates, trim, LCD panel indicators and is switchable from Mode 1 to mode 2 (reverse stick assignments)and only takes four batteries instead of six

heres a vid of that helo

there are more but this one shows close up of the play in the rotor head, not trying to talk you out of it but you should look at some of the videos posted for the various brands and see what you can expect from it, the Xieda is made by Great Wall. Most if not all of these are made in China and there are a wide variation in quality between them.
