I understand completely about your "keeping it as intended" attitude on these classic designs. I always enjoyed building (some cases more than flying). The biggest enjoyment was to personalize my plans by modifications. I originally had a NIB OS FS60 for this that I saved all these years. I lost this due to stupidity. I left it on the bumper of my truck after getting it out of my storage locker. I may look for a FS60 on ebay later, but for now, I'll just leave the kit in my closet. I do have other planes I should be finishing up anyway.

I did have Falcon II or maybe the III, not sure. But I kept it pretty must out of the box except for adding a dowel in the l/e and bolts for the t/e of the wing. I had on OS 45 fsr w/ a tuned pipe and the little plane screamed. I would do full throttle flybys, under 2 feet off the deck while inverted. The plane was very smooth and predictable, and I trained some folks at our field with it to boot!
The demise of the plane didn't come from a failed wing, but instead from a failed bulkhead. The one that held the front of the wing with a dowel. It was only 1/8 inch thick and I should have doubled it.[:@] The plane did last 6 years this way. I still have the OS 45 from the crash, full throttle dive into a tree trunk. I had to dig it out[X(].
