I'm flying the GP small Giles, (they call it the Giles 46), and it flies great. I think GP has lengthened the fuselage slightly over the full scale aircraft, which seems to make it groove a whole lot better. It's AMAZING at rolling manoeuvers. It rolls very vast, very axial. I fly mine with extra aileron throw and lots of exponential. Knife edge is straight with only a touch of down elevator mixed into the rudder.
It also slows down well and could almost be considered a "floater" on landing. It does snap if you set your elevator throws too high, but I think that's true of all aircraft of this type.
I've been flying my Giles for 3 seasons now, and it's still my "go-to" aircraft when I want an airplane that does what I tell it to do with no questions asked.
P.S. And I LIKE the fact that you don't see Giles at the field every weekend. That was part of the reason I went for a Giles instead of an Extra originally anyways.
Anyways, talk to you later,
Tom
