It's great. it's donation ware. ( Or free if you are skint.)
I NEVER thought I would go for gliding a monster sail plane.... but after a few hours of
faffing around on a windy hilly bit.... I'm hooked.
and no invisible trees...
This is the life!
No oily goggles, flack bursts or whizzing shells!
( and the wings stay on... )
but I do have to bring my own crumpets. ( we ran out of R.F.C ones...)
