Opjose,
I burn 16 OZ in a ten minute flight with the 1.60 Flying pattern manuevers (alot of vertical)
the BGX is 9 more CC's so I would think 20-22oz for a similar flight. (Not all WOT)
and it costs $250 less than a top of the line 50cc. Maybe not the best for 3D but most likely
a good candidate for IMAC style flying if you don't mind the fuel cost. I think OS should send some
our way for some good field testing.
