Almost "NEW" Enya .29-III Super Typhoon purchase (last week)

GallopingGhostler wrote:Nice acquisition, sosam117, don't see many Enya .29's these days, and an earlier square venturi throat one. Seems most common are the .19 with a jump to .35.

I gather that the uncompleted music wire throttle horn was because the standard digital servo wasn't common then, left up to the owner to complete.

It could be any mode of control: escapement, linear servo, rotary servo, galloping ghost actuator, etc. Motion of travel wasn't standardized yet.

Still, a nice find.

Only .29 I have in my collection is an NOS Duromatic McCoy .29 with venturi.

The previous owner said that he misplaced the square aluminum venturi intake for U/control (free flight).
With the straight venturi, you have to accurately measure your fuel so it would shut off after so many minutes.

With the engine I have, (Enya calls it a throttle valve), you could use the wire on the throttle valve to go to a timer and shut off the engine by closing off the venturi.

I know with the rear intake venturis; you use some type of plug to push into the venturi to plug up the intake and cut off the air coming in. (with a timer to activate the plunger)

On my free flight planes, I have a timer (Texas or Tatone timers) that pinch off the fuel line to stop the engine and the 2nd part of the timer pops up the tail (after a certain amount of time) to dethermalize (DT) the plane to bring it back down.

Thes old timers are getting harder to find now.
But the digital timers are much more accurate ---- when available (in stock) as not many places to purchase them from.
