Buz brought up cross wind landings in the last set of messages. Very timely. March came in with a bang last week. I went flying Saturday with Barry Grant who is interested in a Lightning, and we picked the worst wind conditions I've had with this new airplane. Bumpy air up to 7500', Landing conditions at 17 to 18K with gusts to 25 and wind directions variable. Four landings and TOs at 3 airports. Every time I picked a runway based on the current wind direction, it changed to a 90 deg cross wind by the time I lifted off.
The bottom line: In none of the takeoffs or landings did I run out of aileron or rudder. It is safe to say that I have a demonstrated cross wind capability of 18+K at or near max gross. Performance at lower weights was about the same.
I do have a recommendation for takeoffs in gusty wind conditions. Hold on the runway until you have about 5K+/- over normal lift-off. Then use the extra airspeed to climb quickly to 20-30 feet above the runway to avoid being set back down by a gust.
Note that these are observations for my airplane, in LSA configuration with vortex generators. Your airplane will be different, and you should do your own testing. All disclaimers apply.
