More Motors, More Rotors, More Better
Fore reliability and redundancy reasons, the little hot rod of a quad I previously built is turning into a hexacopter. Some of the electronic bits, and firmware are getting an upgrade as well, but thats part 2.
The featured image is a dry fit up of the airframe, and some of the bits and bobs scalped from the quadcopter. Check out the parts list below, and the fabrication photos.

I mocked up the geometry into usable templates on DesignSpark Mechanical, and then printed them to scale. I then used a water soluble gluestick, to bond my templates to carbon fiber. Out came the mask, because carbon fiber dust and the human airway don’t like each other. Not unless you want the black lung… Cough Cough
Straight cuts can be done with a fine toothed hacksaw, so long as the edges are protected with tape. Everything else is done with abrasive cut off wheels, and belt sanding. Drilling holes in CF is a pain, slow and steady with a good bit is the only way to get clean holes. Large holes need to be progressive drilled to a larger diameter. After the dry fitting, some holes were ground larger, and all edges chamfered.
