Allen,
The serious stunter needs a lot of details to be worked out. I will be working on this over the next few weeks. All I can say at this time is that it will be electric. It will be a comfortable size to fly, slightly larger than the typical Classic, but certainly getting away from the behemoths. IC power could also be used.
I have a set of Hobo ribs if that will help. I do not have anyone making Hobo kits, maybe in the future.
