Top plate only has holes for the boom supports, bottom plate is a little wider for supports for the lower electronics plate
Very basic mounts. Can be used in coaxial mode very easily.
Yaw control. No slop and it is just a 450 main rotor clamp screwed in the boom.
Lower frame plate with all electronics mounted on double sided tape, also has the battery and the GoPro on it.
Booms are mounted on the frame the same way the motor mounts are, simple pressure.
