OpenRC Parametric Chinook

OpenRC Parametric Chinook. Software: https://github.com/projunk/ChinookESP32 This is a parametric version of Tom Stanton's Chinook design. I have tried to make the Chinook fly using a naze32 flight controller with both cleanflight and betaflight, but could not achieve stable flight using the PID values that seem to work successfully for other people flying a similar design. In the end I decided to program myself the flight controller software using an esp32 development board and a mpu6050 gyro/acceleration sensor; Joop Brokkings excellent tutorials did help me greatly with this. The developed software has been included with this design. The advantage of using the esp32 was that I could use the second cpu core to run a webserver which shows the telemetry allows changing PID settings on the fly. Finally I achieved successful flight this way.
