Slope Gliding an Aerobird? I never thought of that.
Yes its great fun, most of the time is with the engine off, I use the engine only to gain altitude if I get too low and also to bring the AB into land from behind the back of the hill, which was and still is a real scary moment for me as there is a lot of turbulence.
the longest I've stayed up for is about 30 mins, the AB could have stayed up longer I think, but I bought it back before the batteries get too low as it needs full power to get it to land against the wind.
Ive not been doing it long and I wouldnt say I'm good at it, and the AB is not realy a slope soarer but it can do most things and like you say, its practically indestructible.
