Maintain minimum ground speed

Is there a possibility to maintain a minimum ground speed?

Reason: this week-end we had a windy day and I ran into the situation where the plane was circling nice to high altiude at full throttle but as soon as it reached the desired height it was not able to fly my Easy Star back into the wind at cruise speed on the auto pilot. It was already getting late had some trouble to get the plane back in manal flight as it was on the edge of visual range :shock: .

Currently I can think of tree options:
- use SERVO_SET to go full throttle when I flip a switch (not sure if it will work).
- Allow the tx throttle to override the autopilot throttle e.g.: center = auto pilot throttle, down = decrease autopilt throttle, up = increase autopilot throttle.
- Create a p-action for ground speed to throttle so that less speed then the minimum speed increases the throttle proportional.

Perhaps something better is already availabe and just needs to be discovered by me!

Regards,
marc

Hello Marc,

This question has been asked before and is on the todo list.
The current solution would be:
- Go to the easy config and change the cruise speed (if you have an XBee link)
- Use manual throttle in case of high winds

In the future I plan new functionalities similar to
- A new navigation command: SET(CRUISE_THROTTLE, 70%)
- Next to altitude hold, also speed hold or minimum required speed

(they are on a large todo list :-) )

I suppose this would solve this kind of problems.

Good. Time can wait...
Is there a prioritized backlog available? Perhaps make a sticky in theforum...
