I want to use iNav in my LR quad. That requires a compass, which is missing in BN-220 gps module. Got BN-880 and awesome Matek's F722-PX FC to try. So actually old Badger got partially rebuilt.

As compass is very sensitive to any nearby currents, I couldn't put it on the arm as I usually so. Have to design a rear mount for it.

Weight without battery and GoPro: 395g

Waiting for maiden and endurance measure.

UPDATE 2020-05-28: Got Twist-Lock plate cut from 3mm carbon fibre.

UPDATE 2020-06-03: Rear mount still caused problems with magnetometer. Too much electronics and motor's magnets are affecting on it. So had to put it on the mast above the quad. I had 9x5mm CF pipe, so modelled a mounts around it. See photos below.

Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage..

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..
