ok here goes......wind speed has no effect on airspeed.......wind speed only effects ground speed....look at dead eyes post...hes flying in such a heavy wind for his aircraft that his ground speed (speed at which the airplane moves over the ground) was negative..as the gusts lessened his ground speed increased and he made to within 50 yards of himself.....however his aircraft continued to fly...it did not stall, so his airspeed was enough to fly and remain constant unless he moved the throttle.....If he had turned the aircraft tail to the wind you would have seen the airplane rocket across the ground..as his ground speed would have been  65 to 85 mph but his airspeed would have stayed the same......
Whew.....hope I didn't confuse anyone...we as RC'ers tend to think that you see the airplane rocket with the wind that airspeed increased..it didn't....I was a flight mech on 727 came out of Memphis one day with a set airspeed, made the turn from north to north east and ground speed shot up to over 600mph as a tail wind was less than 5 degrees off the tail...airspeed stayed the same....
the answer to this drawn out dribble is....you can fly in any ground wind you want...you will have to fetch your aircraft if your max airspeed is less than the wind speed...Good Flyin to all
