Congratulations on your new acquirement, this airplane will give you many flights and fun, the YS 91 is an excellent engine for this bird, a suggestion to use a heavy prop on this engine is in order here, she can go fast but I prefer to use all the extra power to make my climbs about the same speeds as I make my level flights.

Flying mine with the OS 91 is a joy I can only imagine how it will perform with the YS, got any pictures?

Keep us posted on your progress please.
