This is my micro apex 3, xnova 1804 3500kv, crossfire69, runcam hybrid. I had to use 2mm spacers, and tpu printed camera mounts to accomodate the height of the runcam hybrid. i really love this quad. Oh yeah i had to redrill stack mounting holes because my stack uses m2 screws which made the 2 sets of stacks very close to each other front to back. I really had to get inventive to make it work the esc is in the back and, i had to mount the fc stack in the front with the harness facing forward unlike you would normally do when you mount an esc, and stack front, and back. I had to repin a wiring harness that was long enough to run from the front to the back to be able to hook them up. Glad i used to be a mechanic. So if you try to duplicate what i have done keep in mind you have to be a little tricky. It was a problem solving type deal one after the next. It is a great flyer though, and the footage is really nice no jello.
