RE: Getting back into the hobby!
There has been a lot of discussion here on RCU regarding the Hanger 9 PTS system. Some say that it's not that great a trainer, and once the 'stuff' is removed it is not that great of an aerobatic aircraft.
If you want to go into aerobatics, I would suggest a low-wing trainer type aircraft, something that is for the beginner to intermediate flyer. Suggestions: Goldberg Tiger 60, Sig Four Star 40 or 60 (I would prefer the 60 for the visibility of the larger size aircraft), the Goldberg Protege (although a high-wing aircraft, it is not a beginners level plane, but more of an intermediate level with a bolt on high-wing setup with a small amount of dyhedral) or similar type of aircraft, there are quite a few around.
The all-in-one aircraft are not that great at everything, nor that great at any one thing. From what I have read here, the PTS is not well powered, and has some other issues that make it not that great a trainer, nor a second aircraft.
Do a search here on RCU and read up on some of the postings about this aircraft. Some are positive, but there seem to be more mediocre comments than good ones.
