Thanks, Raipe! I did a little homework on the Myrsky. I didn't pick up on a complete absence of aerial victories, but I did see that only 51 were built which would definitely limit their exposure.
Speaking of exposure, I too read that they were prone to coming unglued in flight. Something about a combination of high speed, Finnish winters, and plywood construction. Who would have thunk it? You'll probably be ok if you keep yours inside the hangar between sorties.
I don't know anything about Inventor, but you can always ratio a result from some other material. Not exactly the answer to your question, but a solution none the less.
Take care, Paul
