My next plane is going to be a Global Freestyle. I am returning about $90 worth of merchandise to Tower and want to apply that credit toward an engine for the Freestyle.

I'm thinking of one of the following three engines, what do you think?

1) Tower Hobbies 2-Stroke .61 Ball Bearing ABC - $89.99
2) Magnum XL-80RFS 4-Stroke - $169.99
3) Thunder Tiger F-91S 4-Stroke w/Muffler - $179.99

I'd love to buy my first 4-Stroke; I love that 4-Stroke sound and have read that they are more fuel efficient (but harder to tune).

Any input is appreciated!
