You will find the the elevator becomes canceled at low airspeed because of the fat fuse before the plane actually will tip stall.. Most of the failed landings you will run across with the GB are when people try to glide them in too flat and lose airspeed.When the elevator becomes canceled you will find yourself buried full up elevator and the plane thudding in on the mains then onto the nose and over on it's back.. If you can get used to the delayed reaction on landing from the elevator inputs you will have no problems. It is easy to get into the rollercoaster, balloning up and down. This is a short coupled high wing loaded aircraft and must be flown as such. I have around 50 or so flights on mine and it has been a learning curve, but a fun one... I have an OS1.6FX with an 18X8W APC.. The plane balanced as per plans. It slow rolls and point rolls with no rudder coupling on a string.. Tracks like a pattern plane in the air..

Take your time with it and if there is the slightest cross wind leave it parked.. Cross wind is you enemy...
