Hi Doug, just wanted to follow up with you on the balancing you did on my Aztec at KANE. Ive flown over ten hours including our trip back to FL. I could definitely tell the difference. Now able to fly at 2200-2300 rpm with very little vibration. Thanks! Marc Miller, MCM Aviation LLC
Hello again Doug,
Doug...Just wanted to let you know that my Thorp T-18 now runs much smoother, and the instrument panel is no longer a blur and making an annoying high frequency rattle. What an improvement, and what a relief when I thought a new prop was the only solution...Dave Gunderson
Dougó I sent the check and a letter to you today. The plane is so much smoother, it is fantastic! It feels like a turboprop instead of a Sopwith Camel. I put a big vote for your services on the International Comanche Society website. Thanks so much for your careful, precision work. Iím totally thrilled.

Doug, Well I am very pleased with the results of the dynamic balance, and will definitely recommend you to everyone. What a night and day difference. My instruments, and I thank you. Tony Gasta, Cokato, MN
Thanks for the balance yesterday Doug on the Cheetah. It really seems to make a difference. My wife noticed that the sun visors are no longer vibrating on their mounts and making noise against the headliner. The whole cockpit seems more settled and I'm sure we'll have less pilot (and passenger) fatigue on the multi-hour flights. I'll bring up this up at our next EAA meeting and see if anyone else needs a balance in our area. Best Regards, Andy Hutchinson
