The engine is fine and plus when it's a 4 stroke it normally means its about .10-.15 lower in 2 stroke terms. As in a .65 4-stroke is comparable to a .40-45 2-stroke. Plus it's older, not to mean anythings wrong with it it just might not have the same compression as it used to. Only problem with it is, is that it will be heavier, so make sure to balance it well.

The Eagle-2 is a great plane too. Every club trainer at our field trains with them and the only thing to modify when you buy the ARF or any ARF is that ARF are put together with hot glue and so you will want to order triangle balsa and glue it to the bottom inside of the fuse to reinforce the seams. Also glue triangle balsa to the base of the vertical stab for reinforcement of it breaking off in a bad landing or hangar rash cause no one likes hangar rash!
