DIY Avionics, Kitfox Flight Test

One thing that we’ve seen a fair bit of on the internet is how simple an EFIS can be to create. You just need an IMU, a common motion processing filter (Madgwick or Mahoney for example) and you’re off!

I’m not going to lie, I thought similarly. It took all of 2 weeks to code up a quick demo with the Bosch BNO055 IMU and on my desk it looked like a million bucks! One flight in the airplane and it was obvious that there was more to the puzzle.

Almost a year later and we’re still working through the details of what it takes to make a solid state IMU based attitude indicator. If you checkout other DIY Avionics places on the internet, none of them have real flight tests!

The biggest challenge for us so far has been the coordinated turn. This is the case where the gravity vector doesn’t play ball with the gyro integrators. We’ve made some great headway in the last couple weeks and are getting close to where we want to be. One thing that is for sure, is our hardware platform is looking fantastic!!! Stay tuned!

  1. I look forward to your progress. I’ve been flying a Kitfox for the last 20 years (N42KF) and a biplane for about 15 (N42BP). The Biplane is in need of an update. It has an original MGL Stratomaster that has finally given up. I don’t fly it much so a DIY project for a basic panel is perfect. I have degrees in Electronics, Aerospace, and Mechanical Engineering. I’m fairly tech savy and play with Arduino’s, Pi’s, 3D printers, CNC machines, etc. I can prototype pretty fast and would be happy to fly some stuff! keep me in the loop 🙂
