I remember the article. MA perhaps?  I was fascinated by it's good looks.  As I remember, last read the article 10 years ago, He had a power & fuel problem.  Could not get good consistant runs with good power from the TD.  Tried a diesel, good power but a fuel draw problem. He solved the problem with a strange angle to the tank.  If I build one the engine will be a Norvel. The tank will be one of those little Red Caps used as a bladder.  I would get & read the article before building.

I did a search and found nothing on "redcaps". What are they?

Check your local Ace hardware & Ace on line.  A little red condom like rubber cap that is placed over the nozzle of a caulking gun to prevent the tube from going bad.

wasnt there a kit of the 1/2 A T-Bird  i seem to remember seeing one

There was a smaller sized T-Bird kit back in the 60's. I built one and powered it with a Torp 19. Much too large for 1/2 A engines. Don't recall the wing area but probably around 400 sq inches.

Don,
I think that was the VECO Little T-Bird.

There is another model called the Baby Bird which I am assuming is different to the Tom Dixon one (The plan credits the designer as Don Martin). Around 350sq". Quite a long thread on the Barton site about the Don Martin Baby Bird with revised plans.
