Ron, I thought about the radiator thing, I don't know if it is a good idea to have the radiator right behind my head, sure would be easier to hook up, no expansion tank etc. the Rad I am going to try to use is one out of a Honda goldwing. We'll see how it works.
I haven't done much on the gyro this weekend, I have been working on my shop.
I have all the insulation and drywall hung, I am going to try to paint today, and get the floor ready to paint. Then it's back to work on the gyro.
