First off, Hello to everyone... just spent some time trolling over the boards a bit, reading what you all have to say. Finally decided to post... you all seem to know what you are talking about.

Anyways, on with the question. I purchased an Avistar Select a few years ago. I learned to fly it back then, took some time off, and have recently begun flying again.

I've found that I was able to pick up the controls and solo fly it no problems, even after a two year hiatus.

I am able to pull the thing into simple aerobatics: rolls, loops, inverted flight, stalls, etc... I'm finding that I just want the thing to have a little more umph. Are there any "cost effective" upgrades I can throw on it to give me a bit more power?

It is currently stock with the OS .40 LA engine and a 10X6 Master Airscrew prop.

Biggest issue with enhancements is that they have to be fairly cheap... I can't seem to convince the wife that I NEED more power!
