I just mounted my SK450 frame on a XproHeli landing gear platform with camera mount. I'm going to make a wight that weighs as much as a gopro, mount it and test. I figured I should see if I crash first with some dead weight.
The landing gear costs 3.5x more than the actual sk450 frame. But I didn't want to learn on an aluminum frame since I figured I'd be crashing quite a few times while I get used to flying quads.
