Love this frame. The 1/2 inch booms are an easy fix yourself too if you crash. Learned to fly multirotors on this frame, although I don't recommend this setup for a beginner, these high kv motors are for aerobatics.
on my T copter i use the gopro tripod adapter mounted to a 2"x3" piece of ply. i then use Velcro to mount the ply to the body. i use my gopro in the case and this gives a nice breakaway if it goes in. i get no jello as long as the props are balanced. Nice copter. try it on 4 cell
