I quite often refer to an experimental aircraft website which is quite useful for design and materials sections. If you google "" it should take you there.

Even with the volumes that the Thatcher designs have sold, there is barely enough income to call this a full time job, let alone pay for a stress engineer or make an actual profit. He's made that money over 7 years so that's $23,350 a year. He's now in his late 70's so he was probably already financially sound and not relying on the income to feed the family.

Selling plans is probably a good way to supplement a pension, but even at US volumes it looks like a "get poor quick" scheme rather than a viable business model.

Point taken about not being a good basis for a business but it's a fantastic return on a hobby!

The Corby Starlet and Kestrel - Design background

Post by Hamish Mead » Thu Dec 22, 2011 12:45 am

I just discovered an interesting article written by John Corby, designer of the CJ-1 Starlet and CM-2 Kestrel. It was published in SAANZ's magazine, Sport Flying earlier this year. It would be great to see it reprinted in Light Aviation for the benefit of a wider audience.

In the meantime you can download a pdf version of it from the SAANZ website here:
