V-22 Osprey 2025 Update
It's hard to believe that this project is already 6 years old. I never thought in 2019 that I would still be pursuing this idea of making my own V-22 RC model. It hasn't been 6 years of continuous work, that's for sure. I seem to move in fits and starts, making progress here and there, getting frustrated and putting it away for months at a time before diving in again. This is a list of challenges I'm having: Poor quality of IMU chips Improper PID tuning leading to stability issues Near overload of rotor motors Poor quality of IMU chips The dRhemFlight VTOL project leverages inexpensive MPU-6050 6-DOF sensors. While inexpensive, recent batches of these chips have been unreliable. A previous unit in the Osprey decided it no longer wanted to interface regularly with the Teensy microcontroller via I2C. Another one in my F-35 VTOL (another Nick Rehm design) would occasionally "lock out" and return bad data, causing a crash. After these two recent failures,...
