theres some good advice here, many thanks all!

turbulance is also playing in the back of my mind as our field is covered by tall thick trees at the front, and a few trees and bushes on the sides (the back is clear and extends into the horizon over fields and whatnot) and even in docile winds i can see the tail swinging a bit, ive seen some of the Electric fliers fly backwards in winds where my big gasser would be happy [X(]

is wind less of a factor with bigger planes or is it easier to fly in wind with smaller planes? (such as a 4* 60 and a 4* 40)
