RE: fighting the wind..
The flat bottomed wing on your trainer has a lot to do with the way the wind pushes it around along with the light weight of your trainer.
Get some hours under your belt and that wind won't bother you a bit. In fact, it makes it more of a challenge and more fun knowing you are in total control instead of the plane controlling you as it does to most beginners.
Hang in there...it all takes time.
Get that Tiger .60 going and you won't have to worry about any wind period!
