“I endorse his quality workmanship...”
June 6, 2004, To Whom It May Concern, My name is Scott Resnick, I am the shop foreman and manager of Northwest Aircraft Maintenance, Inc. of Hillsboro, Oregon. For five years I had the pleasure of having Bill Larson, now president of Oregon Aircraft Design, work as the lead mechanic on more than 80 annual inspections. Bill consistently showed a level of safety and trustworthy maintenance which gave me the confidence to sign off his work day after day. Bill’s innovative designs lead him to start his own business which has been able to help the aviation community with safe and effective products. I often install his products to protect the long term investments which my clients have made in their aircraft. As a pilot I have flown with confidence behind engines which Bill has maintained, some for more than a decade. We have never had a maintenance related incident, or accident in the fleet of more than 100 aircraft on which Bill has performed maintenance. Without reservation I endorse his quality workmanship and high level of safety. Sincerely, Scott Resnick, 503-648-3670, cell 971-409-8308
“All the way to Oregon...”
Hi Bill, I just wanted to let you know I finally flew my gyro the other day for the first time and the engine ran perfect. When I told my flying friends I was sending my Rotax 503 all the way to Oregon to be rebuilt by Bill Larson they thought I was nuts. But now they see how nice the engine looks with the custom paint and how well it runs. No one is laughing except me enjoying the air time. Thanks again, Bill. Fair price and great job!!! Jamie Cleary 503 Air Command Gyro Darlington, Md.
“Very good price...”
My 582 was running fine with over 6 years without an overhaul. After consulting with Bill I discovered that Rotax recommends replacing all the engine seals at 3 years or 5 years maximum. Bill overhauled my engine, including performing all the precision measurements, cylinder hone and replacing all the seals and gaskets. He also gave me a free log book with a professional A&P entry and a written warranty. The job was completed in a timely manner, very good price and the engine runs great. I would highly recommend Oregon Aircraft Design to anyone. Robert Case Work # 503-526-3462 Home # 503-647-2077
“I would highly recommend Bill...”
"At first I thought, What am I doing, sending my 582 to someone I’ve never met? Bill requested that I ship my engine to him so he could inspect it and tell me what it was worth. I thought Yeah, right, but for some reason, I decided to take the chance. Bill notified me by E-mail as soon as the box arrived and quickly thereafter e-mailed me with a detailed report of his findings and the amount he would offer for it. I was pleasantly surprised and accepted the offer since it was fair to both of us. Bills check arrived within one week. Based upon his honesty and integrity, I would highly recommend Bill Larson and OAD. Sincerely, Ed Cully Arizona, Home: 928-527-4118
“My 503 is running great!...”
William, My 503 is running great! I installed it on my t-2 back in september after I finished fabricating the fan-shroud and the rest on the support bracing . It fired up with no problems at all, once the carberators were set-up, adjusted and trimmed to run together. My set-up is running an E drive 3:1 65" B blade which was producing 350 Lbs of thrust static measured at Don Stutts place back in Dec. You have one satisfied customer here and will gladly reccommend you ! Glenn Duhon
“It always impressed me...”
The Hirth 110 hp Fuel injected F-30ES is a great engine. I used mine in an experimental helicopter for 85 flight hours. There's quite a bit of shock cooling involved in practicing autorotations, and that's the great thing about a Hirth -- it's resistant to the effects of shock cooling. It always impressed me with how reliable it was, which was magnified by the fact that the rest of the helicopter was rather nerve-racking. These engines are very tolerant of heat, and aren't as loud as you'd expect. I'm parting out the helicopter and would use this engine in some other project if I had one. Jacen Keller
