This is a very rugged frame ( survived several severe crashes ! lol )
I've finished the baseplate for all the electronics .. (see last 4 pics.).
APM2.5, minimOSD, FatShark Video transmitter, 3DR telemetry radio, Turnigy 9X receiver and Optflow sensor.
The files for the all in one system start with 'AIO' ..
print and tie-wrap together.
mount electronics, make custom cables and connectors ...
You can see it fly here:
I've build it with 8mm aluminium tubing.
It has to be assembled with 2 long tubes ( i've used 60cm tubes )
and 4 short ones ( i think ! 24.7cm ).
Everything is secured with m3 nuts and bolts ( and washers! )
It only ways about 160 grams with the base, motor- and ardupilot mounts.
I've also made an multiwii SE mount.
But it's easy to draw your own mount for your electronics.
