So far, this is a straight copy of Vilamany's drone frame, but I am using the NAVIO2 and Raspberry Pi, so will modify top and bottom plates as needed.
Still a work-in-progress.
0.1 for legs. 0.24 elsewhere.
50% most. 100% legs & plates
Red & Yellow!
I have ordered brass M3 threaded inserts, but discovered that the 18mm M3 bolts seem to "self-tap" very well and the drone has been assembled using only this method.
See how it goes, but it may be stronger than relying on the inserts.
If it disintegrates, I'll add photos ;-)
