Recently I tried the VTOL Quadrotor X Tailsitter, however I have some questions about this kind of airframe.
1, For some reasons, I can’t use four same motors, and the motor 1 is same as the motor 3, the motor 2 is same as the motor 4. So can I finish the transition from MC to FW ?
2, I didn’t use the airspeed sensor. And I set the airspeed mode (FW_ARSP_MODE) to ‘declare airspeed invalid’ in the parameter of QGC. Should I use the airspeed sensor? Or I can use the ground speed to replace the airspeed ?
3, When I try to get the transition from MC to FW, what should I do first, toggle transition switch? Or I make my aircraft pitch for a certain angle?
4, How can I make sure that my aircraft have finished the transition when I get the data analysis from LogMuncher or Flight Review or when I test the aircraft?
I know I haver asked many questions, but thank you very much.
Which config did you select? Can you post a log?
- This is probably a configuration issue, but I need to know more about your setup.
- Tailsitter transition currently depends on airspeed, although this could be changed.
- Just keep it level, flip the switch and the controller will do the rest.
- Make sure you’re using the new logger (SYS_LOGGER 1) and upload logs here - http://logs.px4.io/. A VTOL log will have an additional plot showing the VTOL states.
Thank you very much. I used the traditional log analysis in the LogMuncher. Should I try the new Firmware?
Yes in general I would always use the latest stable PX4 and QGroundControl, however there aren’t specifically any tailsitter changes.
