I have flown one before with a OS 91 fs, it was doggy because of all the balance weight required in the nose. I had a Lazy Ace that flew well, very scale like nice plane until I let someone fly it and he did exactly what I told him not to do!
He was lucky to leave the field alive! I shamed him into paying for it.
I will post a photo when completed, snowing this am so will spend the morning working on it.
