Initial Conversion to APM: Plane:
I’ll start the thread with my initial conversion to APM plane. The Hobby King Bix3 Trainer comes in ARF and RTF packages and all the spares are inexpensive. There was virtually no work needed to get this plane flying!
My Bix3 build is meant for a shorter range test bed for use at a smaller local field. I used a Pixhawk clone in my Bix3 with my favorite Taranis + radio system. In order to reduce noise and make room for the flight controller, I moved the 20-amp ESC outside like it is on my Skywalker.
The FrSky X8R receiver makes it easy to connect to the controller and 3-axis gimbal using SBUS. Inside the FPV pod is a FrSky SBUS to PWM converter. The FatShark 5.8GHz transmitter connects to the Lipo pack charge/balance connector. Everything calibrated fine and works great on the ground in both manual and FBWA modes. Note that this setup, along with my long range Skywalker and copters all work with my APM Antenna Tracker due to the 900MHz telemetry link.
The near 9oz Multistar 3s 4AH pack balanced the Bix3 perfectly. I’m not sure why HK recommends an 1800mAh~2200mAh pack. Anyway, the 4AH pack will give a much better flight time. I added some Velcro straps that just fold over to lock the FPV pod in place.
