I guess it all depends on what you really want to do. You can continue sport flying, or go 3D, or pattern, large scale gas, scale, whatever.

What I did, and this is by no means a recommendation, just something that guided me through the past seveal years, is I went to a low wing 60 size and started to learn maneuvers. Controlled maneuvers. Meaning, knowing what happens next and what happens after the end of the maneuver. This sort of led me into Pattern, which is precision aerobatics, however, I never competed with it, just enjoyed learning the complex maneuvers, and trying to do them well.

Some are contented to fly warbirds. Building them, and making them fly can be a challenge, as can a lot of our hobby. There are so many aspects of it that I would suggest that you go through some of the forums here on RCU, and they are all covered, believe me.. and see if there is anything that strikes you fancy.

My second plane, by the way, was a Tiger 60. The pattern pro at our club said that it is a capable aircraft, but doscile as a trainer. Several of the pattern folks said that it was a good way to get started in the world of pattern flying (precision aerobatics done in a patterned sequence and scored accordingly by judges). Mainly because it was so capable, and easy to fly. It can be set up to fly as straight as an arrow.. hands off.. which is a solid pre-requisite for a pattern plane.

Then, I also enjoyed (enjoy.. I still do) flying my sport planes. The Kaos is a great next step, for sure.
