RE: Eagle 2
My friend has an eagle 2 and I use to have a pt40(very similar to eagle). We fly off of grass and when the grass was longer we had a hard time getting them off with 40's. So we bought 60's and put them in and after that wondered why we ever started with a 40. It is a lot of power for that airplane but so is 500hp for a corvette.
WE never had problems landing but we did need to extend the nosewheel up a little to run an 11inch prop. I would go with it and see what you get. If you don't like it then go spend the money on a new engine.
