Default Throttling the non-thottled Cox motors.

I ran across an old article on making a throttle sleeve for the .010 and .020 motors. Not sure if anyone remembers seeing this but I thought this would be the best place to share this info. I know skaliwag makes some. How close is there in comparison?

I hope someone here will find the information useful as I have no machining equipment nor the experience.

Mine is pretty much the same principle. Although I have one of the Vogt units, I had the ideabefore I knew about it. I got it from Easy Tiger. Some of the dimentions in the chart I find to be on the loose side, especially for the 010.

I was wondering about those dimensions. I realise that the smaller you go the tighter the tolerences must be. Thanks for you thoughts.

Hi BL,

Interesting article. It looks like the idea has been around for a while. My 2 centavos are if you want to throttle a .010 or .020 by Steve's (Skaliwag) units. I have both units and can't say enough about them. The sleves fit the cylinders like a glove, idle is low enough to have your plane sit on the runway and not budge, and transition to full throttle is excelent.

Agree with above

I have a Vogt restrictor too, that I used in a Cox .010 powered Littlest Stick many years ago.
It was fully shut all the time (except for starting the engine).
That took a little off the edge of the noise but didnĀ“t noticeable reduce the power ā€“ which was good because with the weight of the (single channel) radio in those days, you needed full power from the TD .010 anyway

SteveĀ“s throttle rings is different matter altogether. Precision is everything to get this restrictor type throttles to work and thatĀ“s what Steve provides

I was totally amazed to see (and hear!) my TD .020 running steadily at 6.500 with one of his units
Highly recommended!
