The HobbyKing X900 was a great flying machine out of the box. The addition of the RC Logger FPV system and a custom 3D-printed electronics case really made this tricopter shine. Below are the settings that were used in the Mission Planner software for the HKPilot Mega flight controller board (APM 2.5). In the Mission Planner software, you will need to select the tricopter so the software will load the correct firmware. Above are the PID settings that were used to get the best performance on the X900. Keep in mind that these settings were for our particular liking on our machine and they might vary based on the feel you are trying to achieve. But these should be a good starting point. 3D Printed Electronics Cover Files and Photos To keep the electronics protected and the wiring neat on the HobbyKing X900 Tricopter, I designed and 3D Printed this electronics cover. Here is the electronics with the cover removed. The GPS sensor is attached to the top of the cover with velcro so it can be easily removed.
This cover was printed on a
LulzBot TAZ 3 3D Printer . The STL files were sliced using Slic3r and it was printed with: 3 perimeters 3 Top and Bottom Layers 20% Infill No support – the top cover was printed upside down so no support is needed. The Bottom Cover X900-Electronics-Bottom-Cover.stl The Top Cover X900-Electronics-Top-Cover.stl The Sketchup Files X900-Electronics-Cover.skp DON’T HAVE A 3D PRINTER?
