if your super tiger is like mine, you will get good at engine tuning (because it requires a lot) with that engine. anything else will seem easy to tune afterward. now on the other hand, when it runs well, it will outperform just about any of the other engines the same size that i have had the opportunity to play with.

fwiw, mine seems to run best with a MA 10X6 or a wood 10X6. but be warned the wood props you only get one mistake (prop strike) and they are done.
