How to build the lightest Ardupilot microquadcopter 3-inch "2-stack" frame?

(Hugues) #1


This is part 1 of a 3" Ardupilot micro quadcopter build, starting by making a custom light frame able to carry all of the electronics and cameras of a full fledge drone:
-A F7 Ardupilot (ChibiOS) autopilot
-a FPV camera
-Video live tx 5.8Ghz
-Full HD video recording (1920x1080 30 fps)
-Mavlink radio telemetry (real time telemetry on ground control station)
-GPS + Compass
-2S 3300 mah Li-Ion battery for long flight time (to be tested)

The frame is designed to carry two full 30x30 stacks (and has screwholes for 20x20 stacks).

The frame has a protective top plate, so is not only a unprotected base plate exposing the electronics.

This custom frame is a composite made of plywood, carbon fiber elements and balsa/carbon fiber sandwich plate.Such a composite allows to get a much lighter frame than its equivalent in full carbon with the same, if not better rigidity.

The result is a frame with 50% of the weight of the lightest two stacks 3" carbon fiber frame that exist on the market at this time.

A part 2 will be cover the microcopter build…

What do you think about 3d printing the frame?

Very nice, I’ve wanted to build your 300 class frame since you posted it. Very interested in seeing the electronics and how you mount them.

Now I would also be interested in his 300 class frame as that is what I fly at the moment

I added the STL files to download.

To what email can I send them ?

In preparation of the microbuild, I have selected this board as the autopilot:
