I broke in the new ASP .61 2-stroke yesterday at the field and did a few test flights with it and I'm quite happy. It provides a lot more thrust with the same APC 13 x 6 propeller than the Magnum .91 four stroke did and it flies like it did with the OS .61. It isn't a rocket of course, but it does lift off quickly and climbs out with authority and is quite fast in level flight.

The pictures show the mounting with no changes to the bolt pattern required. I did have to open up a hole at the front of the cowl for the needle valve though. The spinner scrape marks are from the Magnum .91 as it was shorter from the mounting holes to the thrust plate than the ASP is. There is pleanty of gap with the ASP.

Now I'll pick up a good 3" dia aluminum spinner to replace the plastic one and I should be good through the rest of the fall and the skis are ready for winter!
