Maybe have a non-profit aviation organization (like a large EAA Chapter) run it with $10K from the proceed goes to them for their effort; you probably can write-off that $10K.
Um, Hung, Did you forget that the Club/Fly-in Foundation is a Non-Profit aviation organization ?
Sorry, that slipped my mind. Yeah, the Club/Fly-In Foundation would be an ideal organization to run that raffle since our club is about 150s/152s, we have a large "fan base" of the type, and most forum members are familiar with Jim's plane.
