last revision had a full speed head on collision with a metal railing surprisingly bot much broken! These ultralights are so resiliant! it was just a couple wires that got desoldered.

since i had it opened i decided to change out the camera to a lighter one. the runcam phoenix nano is one heavy booger. I had to try thr baby ratel as well as hglrc's nice nylon whoop canopy that has a decent nano cam mount as well as a high turtle fin.
