Revised number system….First half.

Note, group 1000 was revised at 6:15 pm est 3/21

Note, group 2200 was revised at 8:50 pm est 3/21

Builders:

Here is the first half of the revised numbering system.  I will have the second half out later today. After that we will have a builder check list, sample build options based on the ‘Alan Able- Eddie easy’ models we discussed last month, I will introduce boxed ‘kits’ that will cover whole groups, and we will revise our parts catalog to reflect these new numbers. All on target to get done this week. Good thing I broke my new years resolution to drink less coffee. Everyone should print out copies of the posts in this series for their own shop build note-book. If you are heading to CC#25 or to sun n fun, having these in your hand will allow us to cover a lot of ground and take notes for your particular plan of progress.  When I am standing at Sun n Fun, and guy has a notebook in his hand, and right beside him is a guy who claims to have followed our webpages but has no idea about this numbering system, I am going to be polite to both of them, but who do you think is going to get the bulk of my time? Which guy gets a regular answer, and which guy gets me to dig out the rear oil case and show him the flow pattern in detail?….. Correct, the guy who brought me another coffee……Just kidding.

About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.
