Chuck,
How big do you want? I can do the extra plan sheets to build the Ringmaster Bipe II or the Ringmaster Tri 45 to be electric. The Bipe II is a 41 5/8 span 413 sq. inch biplane for .29 to .40 size glow. The Tri 45 is a 41 5/8 span 642 sq. inch triplane for .45 to .53 glow. I have one each in stock. Let me know if you want one of either or both with the plans and pieces to go electric.The multi wing airplanes are easy because a wing doesn't have to be changed to accomodate the battery.
I can do the design work to make almost any of my kits as an electric powered airplane.

Thanks, Pat
