Babe Bee venturi throttle
Page 1 of 1
Babe Bee venturi throttle
One of my flywheel vids.. but really shows the throttle-response that can be had when using the "Ace-style" throttle that Cox International had reproduced.
That's a stock Babe Bee engine. The tank-bowl was drilled to accept an external fuel-line. The little mesh-screen was removed from ther air-intake in the rear.. to permit the insertion of the tapered-plunger which meters (albeit crudely) the air and fuel mixture. The tapered-plunger is operated manually by me at the rear of the engine. A radio-control "servo" would operate the throttle in a prospective model.
When CEF member Mark Diedrichs mentioned having a 2nd (annual?) CEF "Cars are the Stars" contest.. it got me thinking. How might we adapt a Jomac/Jerobee type of centrifugal clutch to power a RC car of our own design?

Re: Babe Bee venturi throttle
I like that throttle.. but the exhaust-barrel type seems to be more popular; probably because it's easier to adjust as well as link to a servo. The venturi type (shown) requires drilling an access hole through the center of the firewall for the plunger.. and ample space behind the firewall for a linkage to a servo. Regarding a model-aircraft application; that area is generally reserved for a fuel-tank/cell.
Alternately; the exhaust-throttle type and respective cylinders are generally "mated-sets" (precision-ground).. which can be difficult to source.
A marine application is what I was hoping to build someday.
