Hey all, It's been FOREVER since I have been on these boards. Life happened after college and I haven't posted on here in years. I have flown on and off over my hiatus of this hobby but I am planning on getting back in and am currently trying to finish my kit plane that I started years ago.

With that said, I currently have a Hobbico Avistar(real original when I decided to make a screen name lol) I feel comfortable flying this bird but will definately get more time in since it has been a few years since I've flown her around the patch. Question is, I have an O.S. 40LA in there now. For what it is it does the job but I'm looking for something with a little more umph. The kit I am currently building is a Great Planes Super Decathalon 40. My thoughts are to find an engine that I can break in and fly with the Avistar to make it a better performer, and when the time is right transfer that into the Decathalon? I've had thoughts of a .46 FX or a TT .51? I've read that the Decathalon is a bit on the heavy side so a bit bigger engine would help with that aspect. Just kinda testing the waters here to see what others have done. I'm not looking to make this a full aerobatic aircraft but from what I have read & watched the combination of a bigger engine, larger control throws, and zero dihedral and it has potential to be a nice performing aircraft.

Thoughts? I apologize if this is in the wrong section. I still consider myself somewhat of a beginner(this is still my first plane after all), and the Avistar is an advanced trainer so I guess I figured there would be enough of you with Avistar experience to lend a hand.
