Boy, your only two years older then me and a grandpa! God bless you man. My oldest just turned 13, but I have a younger sister in law who just became a grandma. She's only 38, but she started a wee bit too early.

I've had people tell me keep going with the 32:1 and other says switch to the 90:1. I tried to compromise and did 3 gallons with Lawn Boy instead of 5. Interesting notes on the Props. I figured I was going easy on the motor with the 22 inch for break in, and purchased an NSX 23 to move to once it's broken in. That said, with the Yak and my CF landing gear, I'll be staying with a 22, as there is just not enough clearance. It was also my understanding that a wood prop is better then CF as it weighs less, and spools up and down faster. I don't fly fast, so I wanted something with good torque. I would agree that I'm not getting into the power band of the motor with this prop though, so something that spins faster to get a given thrust would probably help in general.

Bring the Yak or the Cap. THe Cap looks pretty sharp. Which model is that? And which Yak? Not Aerotech, I'm sure. ;-)

Have a good one!
