Built one of those years ago, but sold it after a few effortless trim flights, because someone offered me good money. I thought I would just buy another kit, but never did. I've regretted that decision ever since.
Tower Hobbies now has a laser cut kit of that great glider, but I no longer have the stamina to build or chase one. Link below may take you to the tech notes, so just scroll up or down for the rest of the info.
