Graham-

Dale Kirn has Cox mag pans and all the the stuff to build his daughters 1/2A record breaker "Spullet". I recently purchased the following:
1. Mag pan
2. Glass shell
3. LH TD crank
4. LH glass filled props (unfinished)
5. Plans and article for Spullet (Model Aviation article)

Dale is a super nice guy and he has a bunch of other goodies, not to mention a wealth of information.

You can contact him through the family web site - Google/Yahoo "Dale Kirn"

Well I'll be, I never even thought asking Dale if he had any of that stuff. I am going to send him an email right now.

I did manage to find a pan courtesy of matchlessaero but I was digging around for a LH crank as well but so far haven't found one.

I have the old MA article for the Spullet already.

Thanks for the tip.

cheers, Graham

mylamo,

What's cool about the Spullet is that it has a wheel! As for FUN, I'm seriously wondering if I can spin around fast enough to fly the thing! LH prop or not.

Graham,

What are you using for an .049 speed spinner?

Well, the Spullet and others that use the Cox speed pan don't really use a spinner, front end is much like a typical team racern as you can see from the attached picture (from the original article of the Spullet by Dale and Kathy Kirn)

As for a more traditional spinner when needed, I just make my own. I have been adapting 30mm aluminum spinners made by MP JET for electrics to use on 1/2a size engines but 30mm is a bit large for a speed plane. It helps to have a lathe and a few other suitable tools.

cheers, Graham

Regarding hand launching speed planes...When I was a kid I fooled around with a Peanut, which was one of the more popular 1/2 A speed designs of that era. My dad launched it like a frisbee, holding it by the wingtip and just sorta whipping it. I don't recall ever having a bad launch.
Dad was a speed flyer in the late 40's and they had a lot of trouble with dollies. The mousetrap designs were just coming into use and planes would routinely be bounced off the conventional ones, so HIS dad used to launch their Dooling .61 speed ships. I've heard stories of more than one close encounter between the plane and the back of his head!
