Three questions
1. Is there any way to keep motors running when using a Spectrum satellite receiver when the signal is lost? Mine drop to zero when I turn off my transmitter.
2. I have a DJI Naza clone, what should be my baud rate on the "Hardware" tab?
3. My "position hold" works well but my "return to base" works with a pendulum effect. The quad overshoots and then oscillates back and forth trying to find the base position. I have tried your "dirty" firm ware but it didn't fix it. It did improve the "Velocity Roam" which also results in oscillations if traveling fast.
I got these questions in a PM. It is probably better to post questions in the forum so that others can add comments or learn from the answers. Some people may think that they are asking a stupid question or are shy. Don't worry about it! Just ask nicely in an appropriate place.
1A. First of all, be aware that when it looses RC signal, it must have an automatic command that brings it down or your bird just flew away, never to return. Some RC equipment has only one setting and that is to maintain the last transmitted stick positions. That is the worst possible way to handle this. There is no way for the FC to know that it is out of range and flying away. Betters systems have failsafe settings that allow you to go to known stick positions (e.g. low throttle) if it goes out of range... I suspect that the Spectrum sat rx doesn't do failsafe or that would be one way to set up this failsafe (using RC failsafe) that you probably would have done already. It sounds like it does simply stop sending servo pulses when the transmitter is out of range. That is good. The FC uses this to go into an FC based failsafe. The way to set up FS in the FC (that does the same thing as the receiver failsafe) and gets triggered when the RC receiver stops sending signals to the FC (like some do when the transmitter is out of range) is set up in Input -> Failsafe. Revo class FC's that have GPS completely configured can do Landing mode here as perhaps one of the best options besides dropping out of the air. I like to add a little yaw to the FS so that I quickly know that it is happening if I see it in FPV. Left yaw to the RC failsafe and right yaw to the FC failsafe to be able to tell which one it is.
2A. The baud rate of 57600 is automatically set, so it doesn't matter. DJI/Naza GPS has a fixed baud rate.
3A. I would look into tuning the VTOL PIDS at System -> Settings -> VtolPathFollowerSettings -> *PID and *POSP. If it works well in VR, then it may be that the Brake PID needs adjusting? Play with them all, but set each one back to defaults before moving on to the next one.
