Aerobatics???!!!
I've just watched the video of the Pioneer330 and it was just a series of recoveries from unusual attitudes with smoke, not aerobatics as we would define them. However, the blurb says +6-3 which should be good enough for Standard, at least, probably Intermediate.
Most aerobatic a/c have fixed undercarriage, not sure if the additional mass and complexity of retracts is worth it for aeros. The only retract a/c on the UK aerobatic compeition scene is the Yak 52.
PS those folk clustered around the prop at the end made me wince, somebody should have moved them!
