John -

In our old thread on this history of the rules and versions, I posted the 1952 newsletter which outline the 1953 Nats rules:

Those original rules had provision for a 1/2A class, but I've never seen any reference to it actually being flown -even at the Nats.  Locally, I had a couple of 1/2A models that I was flying with the Cox 3-line handle and a Cox reedy with a rotating cylinder throttle baffle that flew really well.  I even built one with a TD, but never got the plane completed.  Never got anyone else interested in trying it though.  I wonder if there is any record of the original 1/2A event being contested?

Mike,
Thanks for the rules ref.

In the late 60's and early 70's we had 1/2a carrier contests in our area, (Wash DC) , and so did Cleveland. In fact one of the Winning airplanes from that time was raffled off at our Christmas party this year. It was a .049, reed valve. With a exhaust throttle restrict or. The plane was a sig skyray.

That proto type I've been working on is a Skyray.  I need one more part to finish.

looks nice. Have you run that carb yet?

No, I've been teaching after work for a while now and have not had much time.  I have one more night of testing for my class and should have more time.  I have two new carrier planes to test run, hopefully this weekend.
