Hey guys im thinking about getting a helimax blackhawk with carbon blades and some other little hope ups and what not. THe guy i might be getting it from said he likes this over the blade 400 and some of the parts are interchangeable with the T-rex.... If any one know what parts are/are not? Also does any one own one of these? I hear they are pretty much a t-rex with a different name and some little things..... Whats the best place to get parts? Any one do 3D with one and what it needs to do 3D???? Thanks!
