I had one of those senior sportsters, yellow and black. HUGE upgrade with the modern canopy!!! Mine went through a few engines, huge Saito gasser, 52cc side carb thing, and finally ended up with some oddball 50ish cc twin on the nose. We called it the 3DGB because it would hover quite nicely but ailerons were not in prop wash. VERY VERY good flying plane!!! That would be sweet with a small Saito Radial or one of the new small twins like a DLE40 or 60!!! Does your new version have flaps? That would be the only thing to make it better, not that it's hard to land it's just fun to play with flaps. Oops, NVM, I looked closer at the pics. Could modify for flaps / full ailerons though!!
