Mark,
What of the tailplane are you considering?

Firstly Belgrade is a difficult hall to fly in, usually with strong drift anywhere from mid height and severe turbulence / drift close to the ceiling. Mastering steering is a must as is staying off the ceiling. the CofG is also a fundamental that has to be carefully considered to ensure you effortlessly climb through the sticky air and recover quickly from any slight stall, dive endured by air movement.
