I agree with bill as to the lifespan of the red heads, though for non demanding uses they should be OK. There is a new old-timer event called Foxacoy in which the McCoy is one of the two engines allowed. As it is a climb and glide event the redhead should provide reasonable life. (The event may also provide a market if you wish to sell).

If you run it use low nitro and lots of castor.
