Summary

I couldn't find anything appriopriate to fly my Lizard95 safely indoors unless waiting weeks to have it shipped from CN. Thus, I had to come up with my own design.

This thing is basically a simplified design of a commercial product available at BG.
(You'll need longer screws to mount the guards to the frame.)

Works nicely for me (3s LiPo, BF 4.0, no PID adjustment)...
