We’ve been talking with our buddy Andy, the “other” fixed-pitch propeller XL/FG builder, about giving his propeller a whirl.   🙂   His is a P-tipped Prince 2 blade, and since his engine dyno tested at a little lower horsepower reading, he was curious how our plane would perform with this prop.

Well, we put in on a couple of days ago and ran it static and high-speed taxi, but couldn’t safely fly it due to really high crosswinds. It spun up about 100 RPM higher on static, and seemed to really accelerate nicely compared to our Catto. We got to fly it today. She does accelerate very nicely, but the take-off roll overall was very comparable to the Catto, and we did have some headwind, so I’m not sure how to explain that. Elizabeth was busy worrying about the prop coming off (she has a high intellectual respect for my mechanics abilities, but emotionally… not so much) to notice the VSI, but the climbout also seemed very comparable to the Catto’s performance visually – check out the video verus the Catto below.

Flying Andy’s Prop


Twice around the patch with the Catto (hotter day, and she was still holding the Fox on the ground to 85 kts back then)
