I've flown with a lot of Fox engines, including the 60. The 60 and 74 are in the Eagle series and are made a little different than the other ones. The 60 is available ringed or abc. I have a 60 abc and it runs great. They have excellent service, you can call the factory and talk to the people who build, test, and repair them in Arkansas. How could this be considered taking a chance?

There must be some internet companies that sell them, I got mine from a local dealer and I've bought some used ones at swap meets and through rcuniverse ads.
