I sold my Decathlon today and am getting ready for my first pattern ship- I can't tell you how excited I am!!! The wise decision would be to pick up something used at the meet in Jackson, and this would take some patience. The next choice is a new Venus II; they are relatively inexpensive, durable, and I have read and understand the directions fairly well.

Either way I need a power plant. Again, the wise choice is an OS 120AX; they are less expensive, reliable, powerful, etc. However, fuel in Vermont cost $30/gallon for 10%!!! So this has me thinking I would like a four stroke, in combination with better low-end power (I don't want to have to keep up speed to start a maneuver, would love to fly past at 1/2 throttle or so and have plenty of power to pull into a loop or vertical up line or something). I understand the 120AX has lots of power, but from what I gather a four stroke would use somewhere about half the amount of fuel? I've already burned 7 or 8 gallons since the first week in may, and that's just on a .46.

There is no one at my field to help me with a YS four stroke, so I'd be totally on my own with this one. I learned everything I know about 2 strokes on this site, and am fairly competent at tuning them (especially when they are not mine, and there's no pressure to get them running). I honestly don't know if it would be the same for a four stroke or not.

So, what do I need to know about YS four strokes? Any advice about what happens out of the box, what is likely to go wrong, and if you want to emphasize that it's the WRONG decision, please feel free. Again I know it's been suggested to stick with what I know and the reliability of the AX to get me plenty of stick time, and if this is the general consensus then I will do that, but I would LOVE to have a YS 110

Thanks guys.
