Joystick doesn`t work with SCHED_LOOP_RATE set to 300 in a quadplane

Bug report

Issue details

I recently discovered that with the SCHED_LOOP_RATE parameter set to 300 Hz, I am unable to control my Dolphin VTOL with a joystick connected via Mission Planner. The ailerons barely move, and at most make a kind of jittering noise. However, if I set the SCHED_LOOP_RATE to 50 (as in plane), the problem disappears completely and the ailerons move smoothly and fully.

HI @raul-ortega,

Thanks for the report, this sounds like the autopilot is running out of CPU and is not able to consume all of the mavlink input. If a regular RC is used, it will probably work fine.

This is not really the place to investigate these issues, I wonder if you've posted in the Plane support forums?

Practically speaking, the best chance of getting this investigated is actually to re-test with the current beta of 4.6.0, then post in the forums here and include an onboard log file and then if possible provide a link here back to that forums post (so that I see it and add it to the 4.6.0 issues list)

Sorry for how involved all this is.

@raul-ortega dataflash and telemetry logs are more likely to get you a quick answer.
