Cox AD-6 Skyraider w/throttle control. Andras and Mauricio passions finally make it to Cox plastic airplanes

Reading the brief hint of text in the instructions, am I reading correctly? To move throttle to low speed or idle position, one gave full down elevator. Then I guess one blips U-control to full up temporarily to toggle full throttle?

Perhaps in this case, the factory idle setting was not full idle, but lower speed? These half-A's don't glide as good as say a .35 powered airplane does. I know if flying my half-A balsa creations, that as soon as the engine quit, if I had any elevation, say 5 feet above ground, the plane, say one of my Sterling Beginner profiles would just sort of fall out of the sky. I had less than a quarter circle if that.

But that then was the difference from a very lightweight balsa model to a heavier plastic one, I guess. (All successful flight experiences were with balsa models, my early attempts at flight with the plastic RTF ones were dismal at best.)

If I sound academic it is because it has been a long time since I lived where I could fly half-A CL. (Too much wind in desert like eastern NM. We may be have calm wind 4 out of 52 weekends a year.)

Very nice example Bob…. I can tell it’s later in Cox history by the other model examples on the box…. I’m curious too how the throttle works… Is there some kind of stop that holds it at hi or lo or does the throttle ring just float?

I guess it is activated against a spring fixed to the crankcase, that recoils when the line controling it is released ?

That is a Nice one !! From the data base any were from 1967- 1996 If it has the 190-6 engine i am guessing its 1974-1976 Product Engine .049 (0.8 cm³)

Manufactured between 9/1974 and 2/1975 (#190-6, ECJ #19)

Engines like this were used in a large number of control line models. Often small modifications like the exhaust ”flip-of-your-wrist“ throttle were used to adapt the engine to the model. The black oxide steel spring keeps the throttle in its position as long as the pilot does not change gear. This particular model was used in a nice Combat Mustang P-51D.
