You might want to check on Ebay for what that engine is going for these days... you could pick up some extra change. Lots of interest in the vintage engines - people still fly them. Most of my engines are old McCoy and Fox 35's, although I am picking up one or two more modern engines lately (OS 25FP, OS 35FP). My big heartbreak this year was totalling a Smoothie I had spent 2 years building. Tried to do an outside loop, wasn't ready...(sigh)
