Go to the Jet Hangar Hobbies website. I'm not totally sure if it's the same A-4, but I believe he did buy BV's old A-4 rights. The plans say (or al least said) Bob Violett right on them.

Currently, BV does not make or sell an A-4. I don't know if the one JHH sells is the same as that or a newer design. Da Fatha (Larry Wolfe) and JHH are in Toledo this weekend, so I don't know if he will be "online" to reply.
