Stiknruda, PICS?!
Yep I started off in the S2B but ended up poling round in an A for a company doing adventure flights - had a brief go in the S1 and taht is what I am rebuilding with a mate now. Fantastic value for money, we bought it with the specific intention to compete in it.
One of the A's I fly had the open cockpit setup but now has the fully enclosed canopy - the first one I flew, an S2E was open cockpit, great fun, but we have access to a variety of Tiger Moths on the same airfield so fly them when requiring wind in one's hair! Besides, side slipping with no canopy is bloody drafty!
