Hi Guys. Hope you are all having a great flying season. I need some help selecting a prop. To start with I am 72. At the present time One of my planes is a Hobbico Kaos.. I built it about ten years ago and it has always flown great. It has an OS 40 FP engine in it. The problem is that I am not comfortable with its speed any more. At the present time I am using a 10/6 prop and Red Max 10% nitro. The plane flies great but it is to fast for me. What would be a good prop to put on the plane to keep it flying great vet slow it down?
Thanks for you help.
