hi hank,
i do believe if you have realfight G2 or G3 you just hit "K" to kill an engine at random. If you have the older version " realflight" or realflight Deluxe this does
not work.I have the realflight deluxe and can't kill an engine on the Volume 3 add
on. Wish i could---i'd like to practice an engine out on the P-38 too as i'm going
to build the Ziroli 114" P-38.
hope this helps
