Project MicroLongRange 20mm Stack M3

This is my little remix of Dave_C's Project Microlongrange, a lightweight 4 inch quadrocopter that is supposed to fly for quite a while on 4 inch props. Here's what i changed:
- i wanted to fly 4S and i have no trust in 16mm stacks when it comes to 4S, so this version has mounting holes for two 20mm stacks
- i also don't like M2 hardware for anything that goes beyond toothpick weight. So i made the center standoffs M3
- i think i found a rather creative way install the TBS Crossfire Nano RX, securing the ufl connector and minimizing any interference with the VTX
- added a fixed angle mount for the runcam hybrid that might be able to hold a caddx ND-Filter with a little bit of adjustment to the filter
- a backpack that holds a proper gps unit and puts VTX and RX antennas as far as possible into the air
- designed a lipo pad that can be ordered at http://www.copterfarm.de using the DXF

If you live in germany or europe you can get the carbon cnc'd for around 30€ at http://www.sma
