Bi copter navigation lights 

This bi-copter use my own design FC, Name is SV79-F411 (stm32f411 with MPU6000 and BMP280). but you can use FC that have stm32f405 or stm32f411 with MPU6000 and good baro sensor. for example ... Omnibus F4 pro V2, Matek F411

@@smith9turbo Brilliant! What firmware are you running? (I've made a bi-copter myself, and used Arducopter initially - but it was a bit unstable in flight)

@@bazabaza7821 This bi-copter use firmware INAV 3.0.2 , this bi-copter have full GPS operation, it can do RTH, way points, position hold.

@@smith9turbo thanks for the reply! I might try using INAV then. Last time I looked at it, I couldn't find a bi-copter configuration in the settings

@@bazabaza7821 For INAV you need to do custom mixer for bi-copter. it will easier if you use Betaflight 3.2.5 it have bi-copter mixer but it don't have GPS way point operations. this bi-copter was tested both betaflight and INAV, both are good. but INAV have more GPS feature.
