Frame complete. Black parts printed in PETG, white parts are ABS. Made a few slight modifications to thicken walls around brass McMaster Carr M3 inserts.
... It Works!
DJI NAZA M V2 with GPS
Motors: Black Widow 4110-460 with integrated 40A ESC
13 X 5.5 carbon fiber props
Zippy 6S 5000mAh 40C battery
Landing gear lift mechanism:
- Diode / Micro switch with 360deg servo (140oz-in metal gear std servo)
- M5 leadscrew drive for high torque (it's slow, but powerful)
First test flight, with FPV footage!.... takeoff, landing gear up, flight to altitude, landing gear down, landing...
Parts I redesigned / modified from original Fragmaster posted files.... the servo mounting top frame portion was a major redesign, much stronger with more material surrounding M3 inserts, and eliminated non-functional portions of original part (saving weight).
Blackwidow 4110 Motor mount and snap on LED clip ... these motors are performance sized using http://www.ecalc.ch/ (IMO, it was worth paying for a few months of use, considering the build investment here!). Also the integrated 40A ESC saved much needed electronics packaging space in the frame of this machine.
I am planning on making further changes and new files as I finish installing additional electronics: 2 watt 5.8GHz FPV video transmitter, DJI Ground Station support, and a 360 degree 5 camera array rig ..... will be increasing bottom cover thickness to add a 12mm thick pocket.

Recommend PETG material for frame / structural parts ... ABS can be used for body panels
