Yes, Blackhawk kits the Demon. It is not the same plane as the VooDoo though roughly the same size. The Demon used a 'diamond' airfoil and back in the '80's, Riley was selling kits of a slow-combat plane (through LoneStar Balsa) that used the same wing in a profile fuse IIRC called the "Diamond Demon". I think that the Demon predates the VooDoo.
