Gents, I did receive an article of MAN about the world RC championships of 1963.

Gents,
I am busy with the next question, did Ed really built in a restrictor in the Veco 45 so we can read?? Why?
When you make the throat of the venture of the carburetor smaller, you generate more sucking pressure. The differences of the fuel level position during the fully aerobatic maneuvers is relative less then, when compare with the high sucking pressure and so the mixture is more optimal and power more constant and better.
But the K & B has a much better breathing?? Does he already have a more narrow venturi in the carburetor, and nearly the same poweroutput as the VECO 45 before his restriction is mounted by Ed.
Maybe Ed was dissapointed about the maneuvrability of the VECO 45 and did give away power for fuel ratio stability!.
But how to tell that to you "fans", read the press.

See the picture!
What about that, even with the restriction in the carb (narrow throat?) a rich motor.
With the K & B 45, the better breather, he maybe had win the game?
