Hostetler Gee Bee
I have a 1/4 scale Gee Bee from Hostetler plans. Mine has a Quadra 52 for power and weighs in right at 20 pounds. My takeoffs are straight as an arrow. Best plane I have had for taking off. I add power and never even touch the rudder, elevator, or ailerons except for minor corrections if it is windy. I builds up speed and lifts off and climbs out without any major control input.
It slows down pretty good, better than I thought it would. It will drop the nose straight ahead when it stalls unless you are aggressive with the stall, then it will drop a wing (left I think). Landings I will keep a little speed up just because the elevator gets sensitive as speed decrease. I know that doesn't sound right, but that is my experience.
The plane is really in its element at full throttle. Everything behaves better and is smoother. The only major complaint I have about the Gee Bee R-2, at least Hostetler's, is that the ailerons are a little sloppy. Seems like you give aileron input and it will start a roll but then the nose will kind of wander. Same thing as you roll out of a turn, the nose wanders around a little bit. I suppose it is some adverse yaw occurring, but it almost acts more like a dutch roll tendency. Not a real problem but it takes a little getting used to.
Nice thing about this plane is the rudder. It is very precise and powerful. You give the slightest input and it goes where you want it to and stays there. Very nice! As for any coupling, there is none with rudder input and really isn't any with the ailerons unless you count the slight wandering.
All in all, the Gee Bee flies better than i thought it would. I wouldn't call it easy to fly but nothing to really worry about. Good Luck with yours...
