i continue to look for a motorglider that has an easy folding wing, since hangars around here are non-existent. i realize the Piuma looks very similar to the Kolb firefly. is it crazy to think about getting an extended wing designed and likely extend the tail boom a bit to create a motorglider from a Kolb? granted it wouldn't be a 30:1 ship, but kept lightweight it could prove to be something fun for local self-launch flights.
