The Revell 1/72nd scale is the only one I have been able to find. 'Flight for Life' here in Wisconsin uses a BK-117, and I'd love to do the kit someday. Too bad there isn't a 1/48th version. The only thing stopping me is that killer paintjob......bright white, bright orange, and bright blue stripes all around the bird, and all the lettering, too. Makes one appreciate the drab paint scemes of military helos sometimes, lol. So many projects, so little time.............
