A fourstroke model is?

1. More Controlable
2. The YS has a built in fuel pump, so fuel delivery is superb.
3. Quieter.
4.The YS 63 produces the same power - as a 90 4-stroke!!
5. Instantanoues throttle response

Sure, you are paying extra, but you are getting the best. And the best in anything is expensive!

I've switched from two strokes - after flying a friends plane with a 4 stroke. It's been expensive but more than worth it!



Besides - the Flip is heavy for a fun fly - Madness 2 looks a lot lighter!
