If money is a consideration, you don't need the Golden Knight. As far as I know, the Saito motors are the same, with only the color being different. If having the black cyliner and gold valve covers is worth the money to you, go for it.

I have two OS 91 4/strokes. They are good motors. If I had it to do over, I'd buy Saito. To me, they are worth the extra money.

With your current building dillemas, I still reccomend the Tiger 60. The Goldberg instructions are very good. It would be an easy build compared to your current project. If the plans don't shoow how to make it a tail dragger, I'll walk you through it when the time comes.

I'm sure the Venture 60 is a good plane. Being up here in the now frozen sticks, I've never seen one. I know Bruce Tharp has quality products.
