Hi Gary,
Wanted to touch base with you. Just to let you know the prop is on the plane and going EXCEEDINGLY well. I initially I thought dad was fibbing with the speeds he was managing out of his Wittman but he is correct.
I flew it myself over the weekend. Indeed the prop is on the numbers. I had to check the airspeed indicator to make sure. But we are getting a true 145 knots at 2500 rpm. So I just wanted to thank you for your time and efforts. You made this home built a surprising little machine.
I have done my best to spread the word of your quality work so I hope we get you some work in future.
See attached a photos of our little W8 Tailwind.
Thanks again Pete
Hi,
Yesterday, I was able to get 2 hours and 15 minutes of flying in perfect conditions so I now have a report on your prop that is accurate.
Static RPM is the same but the take off run is a little shorter, what is really noticeable is the increase in the rate of climb and the cruise speed which is 3 to 4 MPH higher. She will now do 92-93 MPH at the same power setting of 1800RPM.
Vibration levels have dropped by around 40 to 50 percent which is simply amazing.
The finished propeller is beautiful. Using a layer of fiberglass to protect the prop instead of the fabric cover on the original looks simply stunning
If any of your customers ask what I think about your props tell them this:
"I can thoroughly recommend Brent Thompson if you have any propeller requirements, there are very few people with his skills around today, you will not be disappointed."

Hi,
I just came in from a test flight with the new prop. What an improvement. The engine spins up a lot better and revs out in the climb but seems to cruise at the same RPM.
This prop climbs much better than my original prop and there does not seem to be a drop in cruise or max speed. I checked up/down wind with a gps.
Needless to say I am a happy guy. Thanks a lot.
Cheers,
John Lowther
Frankly he makes the best wooden props around.
People seem to get better performance with his props than with factory originals
It's a passion for him, not just a job.
