Products Offered By William Wynne

Welcome to the Products Page.

The parts are listed in 38 groups. The numbers list every single part in a complete engine. If you are rebuilding your engine from a core, the majority of the numbers are for parts that came with your engine. Thus, this is really an engine building checklist, with the parts we sell superimposed where appropriate. Groups after 3300 list components that are used to install your Corvair on specific airframes. To test run an engine at a College, you only need to address the numbers in Groups 1000-3300.

Some groups, such as 2000, have the parts listed individually, but are also offered by us as a complete group kit, which has every number in the group included. A builder selecting a "Complete group kit" will have that group finished.

While most builders are working on 2700cc/100HP engines, we offer 2,850cc/110HP and 3000cc/120HP engine kits. These kits contain all the numbers in both the 1300 and 1400 groups.

Our Conversion Manual, Installation Manual, DVD series, and Web sites explain the way every individual numbered component is replaced, overhauled or reused in the rebuild. For example, number 1602, the pushrod tubes, are covered in detail: how they are cleaned, what color and type of paint is used, and how they are installed. An extensive disscussion of the numbering system can be found on the January and February 2013 archives of www.FlyCorvair.net, in a 20 part series titled "Getting started in 2013."

I have been working with Corvair flight engines since 1989. The first 4 years were exclusively devoted to R&D and testing. There was a lot to learn, and I wasn't going to sell anything until I understood all the answers. In 1992, we began sales of the first product, a small notebook of information gathered from several years of tests. From this beginning, we have sold more than 25,000 individual parts. It sounds like a lot, but it is really just a small number a day, over many thousands of work days that went into the past 20 years. I have played a positive role in assisting hundreds of builders achieve their dreams in aviation. This was not done in a day, it was done one day and one builder at a time over many days.

Almost everything we ship goes by U.S. Postal Service Priority Mail. We do have many builders who have been very patient in waiting for parts from us, and we're very grateful for this. However, most orders are at your place in a week or so. Please note that we do not send out "confirmation notices" when we receive an order. Many people new to homebuilding mistakenly believe that the speed of Internet communication with a parts supplier is a direct indicator of a quality company. I believe that the right answer is much more important than the wrong one delivered quickly. Very quick answers come from people sitting at computers, not craftsmen sitting at work benches making your part. If you want to know something about computers, ask a guy who is always on one. If you want to learn something about engines, ask a man with dirt under his fingernails.

This page also includes links to enhanced descriptions of items that include photographs and drawings of most of the parts I offer for sale. As always, I would like to emphasize that every part I sell has been extensively flight tested, and I have flown behind every one myself. For me, it's always been important to be able to say this. We work in an industry that has people who think nothing of using customers as unwitting guinea pigs and unpaid test pilots. We have never done this.

Engines built to our specifications are eligible for full insurance coverage at the most favorable rates. We have worked hard to make this so. I expended a lot of effort to demonstrate to insurance underwriters that a builder working to our plans and using the correct components is at low risk. This argument is obviously predicated on builders using the correct parts. For example, using a rear starter, or a mount or exhaust made by someone else, disqualifies the plane from coverage at our rates. If you would like to make your own exhaust or mount, or any other part, call me, and I will discuss how we can get you included in the group. However, there are only four other commercial aircraft parts suppliers that we condone using in a "WW" conversion. These are Falconmachine.net, RoysGarage.com, JSWeseman.com and Fly5thbearing.com. If a guy buys components from other sources and later tries to claim that he has a "WW Conversion" on his insurance application, be advised they will probably accept his payments, but if he has an incident, including simple wind damage, his "coverage" is worthless because it is going to take them 5 minutes to prove he lied on the application. This isn't theory, it has already happened, and when the insurance company asked, I had no problem pointing out that the guy had actually bought his engine from a now bankrupt LLC on Barnstormers.com. I will gladly go to bat for our builders on any insurance issue, but I am not here to defend the dishonest while they try to cheat the system.

An important note is that the parts I offer for sale are for Conversion Manual owners only. I sell a lot of Conversion Manuals every year, and I explain to everyone that they are required to complete, sign and return the Liability Statement and Registration Pages contained in the Manual before we will sell you any part that is going flying in your plane. This is why "Information" and "Parts" are listed separately here. You only have to send us one liability statement, once. A number of guys who are on a slow building schedule or who purchased the Manual for educational purposes will take their time in returning their paperwork. But please note that I will not knowingly sell any physical part to anyone who does not have a Liability Statement on file with me. There are a few simple reasons for this, and since I treat all customers as intelligent friends, I'll explain.

1. Anyone who's read the first five pages of the Manual understands my position on risk management and personal responsibility in aviation. Unless you've read this and agree with it, you're not ready to make a purchase from me.

2. The Manual contains the full explanation of why and how the parts are used.

3. It's important that people understand that I do not allow others to duplicate my designs, resell them, or use the parts and information to go into the engine building business. My work is for people who want to learn and build their own engine. I've only had a few instances of intellectual property theft over the years, but I'm sure the Liability Statement has deterred more than that.

Thank you for taking the time to read this and for understanding my position. Loyal customer purchases of my products have always furthered my Corvair research and development. In this way, each purchaser can justifiably feel that they have made their own contribution toward the advancement of Corvair powered flight. It's this support that keeps me working diligently in the hangar. I look forward to dealing with you as a builder, friend and fellow aviator.
