About this 3D model

EDIT: added a upper Centerplate to mount smaller FC´s like naze or mw32 wit 30x30mm mounting holes I wanted a small Quadrocopter for fun and indoor flying. So I created teh Centerplates and a small cover over the FC. The arms are from the Hovership MHQ http://www.thingiverse.com/thing:251002 I only designed the Centerplates and the Cover for the amrs. The Copter has a Motor - Motor distance from 215mm It works brilliant with a HK Nanowii or you can mount all FC´s with 45x45 mm mounting holes. The Parts only weight about 45 gr. with 2 Layers/Top/Bottom and 2 Perimeters - Infill 20% Honeycomb. Motomount is 16-19mm
