Hi guys,
I’ve been developing a Quadcopter over the year and had an issue with the flight using Stabilise mode. Pitch and Roll is working perfectly fine, but as the Quad lifts off it tends to turn clockwise, and there is almost no Yaw control when I try to fix it using the RC.
I’ve read others with this issue, and it’s usually the motor and propeller directions being wrong. I’ve selected a Quad X frame, and the motors spin in the correct directions in the correct order when I complete a motor test, and of course propellers are fitted with the leading edge in the motor direction. However, I still get the same issue with the yaw.
I tried to move the Quad around in stabilise mode without props, and when I pitch forward a lot, motor 3 will switch off, and then when I put it back on level surface that motor does not spin up again. Here are the specs of the Quad:
FC: Cube Orange
Motors: 4x T-Motor U7 kV490
ESCs: 3x T-Motor AT 55A ESCs, and 1x 100A Red Brick ESC
Battery: 16,000mAh 6S LiPo
There is one ESC that is different “brand” to the others, but this shouldn’t be an issue if they are all calibrated correctly. Whilst they are fixed-wing ESCs, I don’t really have the choice to go out and get multi-rotor ESCs ahhaha, but I’ve seen multi-rotors use Fixed-wing ESCs and fly quite well - I’ve even used a fixed wing ESC on a helicopter and it has worked quite well. I also wanted to ask what the difference between Quad X and Quad X (clockwise) is, as they have different motor orders, but that shouldn’t affect it as both configurations have lift produced in the same way.
I’ve attached 2 log files, where the same issue happened in two different tests, a video of the test and my Mission Planner param file. If anyone could help I would really appreciate it!!
