Re: [Paparazzi-devel] Tuning with wind

[Steven Wawryk]

I'd recommend you put the correct date on your system clock because it's hard to 
find your email a second time.

My guess is that your nav_radius is too tight for either your MIN_CIRCLE_RADIUS 
or ROLL_MAX_SETPOINT.

I'd expect that the nav_radius refers to the ground track circle.  With a strong 
wind, the corresponding "air track" has tighter turns on the downwind leg.  I 
don't know if MIN_CIRCLE_RADIUS refers to ground track or air track, but 
ROLL_MAX_SETPOINT will definitely limit turn radius in the air track.

So, try increasing either nav_radius or ROLL_MAX_SETPOINT, and possibly 
MIN_CIRCLE_RADIUS.
