  • does this carb only adjust air flow? if so, then its not a true carb and it will Flood the engine after long periods of low idle.

    i've fitted one of my 0.49's with something simular, but had to remove it due to this problem. the needle and carb must work together.

  • Good Idea !! Does it work at low RPM without the wires attached to the glow plug ?. If it doesn´t try usin a sleeve as restrictor for the exhaust gases to keep the temperature.

  • How much is that engine.

  • there's a much better way of doing this.. use an RC ring..

    check it out -> watch?v=NoABeqyF7pM

  • @earlyhemibill i can see what your saying, however, that dump of vacume would be pressent even at full open, it would affect the needle valves ability to operate by reducing the amount of flow through it. true carbs adjust the fuel flow on the fly as the air passage is opened up, and closes the feul flow when the air passage is closed. now, if you can hook up a full carb to the intake, and just leave the needle wide open, with no fuel, and allow the carb to feed fuel, then that would work.

  • @danratsnapnames Actually I think it could be easy to make it work. Drill a hole in the tunnel below the carb and attach a fitting to it. Add another fuel line to the hose and couple it to the overfow on the tank. After filling the tank, use a tubing plug to seal the tank. As the throttle is closed, a vacuum will be sent to the tank reducing the flow to the engine. It would be like the opposite of a car engine with carb and turbo. Just keep the fuel at the same vacuum as the air under the carb.

  • @beatboxkid8 glow plug uses 1.5V and you can just about run those engines on any model fuel. Preferably a fuel with some more castor oil than synthetic and more than 15% nitro to get top performance.

    Search in the internet for a shop, which is called xenalook. There you can buy these motors.

  • where at can i get one of thes motors?

  • ive made a carb for one before u would be surprised at how low one will idle that was years ago though id like to do it agean and post a vid

  • This vid brought back memories.

    Had a .049 cox in one of those planes that had the handle and 2 strings about 20 feet long that controlled the elevators and went in circles about 30-35 years ago.
