i have flown the bullgog, tutor and firefly M260. The firefly with its bigger engine is leaps and bounds ahead of the other two. Especially at JEFTS when a certain Mr Stu McClaren is demonstrating his inverted 30 degree turn whilst you eyes are close to exploding out your head.
Although i must say that the other two are damn fine a/c as well spent a lot of good time flying the bulldog on UAS and the tutor whilst holding (doesn't roll though).
