RE: Reaction 54 Jet Kit
Actually, it's a very reasonable question. The most obvious conversion might be electric ducted fan to maintain it as a "jet". Less obvious is a prop in the nose. Neither has been done to my knowledge, although a reduced-size Reaction with a fan was built by a modeler in Arizona. I'm not much into electrics, but I'd be interested in a discussion of suitable EDF units, batteries, etc. for the R54.
