![]() It was using the barometer but fusing this with other sensors. There was no magic hardware inside, just an F4 chip. The machine really did NOT want to move and would return to it's exact hight and location. The owner took a boom stick and pushed it down and to the side rather forcibly. I saw a large quad copter set on position hold recently flying indoors. ![]() One solution is to use one software (Betaflight) for racing and extreme freestyle and other software for everything else. The trouble is the amount of computing for that kind of sensor fusion. All the sensors have strengths and weaknesses the filter is like magic and combines the best of each. So the software i not just using the pressure sensor but also the gyros, accelerometers, GPS and possible LIDAR. They run a Kaman filter that fuses the available sensors to track the state of the quad. But other FC software is getting good BARO based flight modes using the same exact hardware.ĪrduPilot is now running of F4 and F7 racing FCs and of course their altitude based modes are dead-on. ![]() Altitude hold may have been poorly implemented and that is way it was removed.
