I've had a few of the Extra330 and one Yak55. What you write about either was my experience as well. For pure IMAC I would take the Yak55, but for pure 3D or both 3D and IMAC I'd go with the Extra. Aircraft International, and I'm sure somebody in Europe also, sells a spinner with a recessed backplate, so the longer 3W fits on the motorbox fine. I have only seen the 3.0m Extra260 in real life, but it looks to fly awesome, although being faster than the 330, which can get you in a bit of trouble on busy downlines.
