Yup, Ark X-400 from Li Chann enterprises, also rebadged under the Helimax name as the MX400.

T-rex is a better quality kit though, so you may be better off with that. I've never flown a t-rex personally, but i've seen a bunch at the LHS and they're nice machines, no doubt. Especially the SE version. From what I can tell, they're aggressive on the cyclic and very nimble in the air. Probably not good if you're a beginner, but great if aerobatic flight is what you're after .
