Depending on what you have to have for it.... AND depending on if you can get it to me, Id buy the whole thing as pictured in the first pic in this thread. You got the bones there for a pretty cool single plus jump seat gyro, that with the right engine, say a yamaha sled engine, or even a Rotax 912 80hp engine, could provide good performance.
I do NOT have the time or desire to drive to get it. But if you were thinking of attending one of Ultracruisers gyro fly in's, I am literally right around the corner from him.
