Dyke Delta contact

Hi all,

I'm looking for a way to contact Dyke Aircraft to purchase a set of plans for the Dyke Delta. I thought I had found the right email address but there has been no response from them. Does anyone know if they have stopped selling the plans? The Delta Builders Network is no longer up (looks like their web hoster is gone as well - astrosurf.net) and the mail list that I think Ernest Christley had running has also closed. So help please! I'm based in Australia so if anyone knows any Dyke Delta's operational in Oz I'd appreciate any information you can forward.

Cheers

James Byles
