How do you set a glowing engine?
INITIAL HIGH-SPEED SETTING With the engine properly secured on a test stand or in the model, install the correct glow plug and propeller and fill the fuel tank. Set the carburetor with the throttle barrel approximately 1/4 to 1/3 open and try to start the engine. It should fire and come to life easily.
How does a glow engine work?
Model glow plug design The glow plug is a durable, mostly platinum, helical wire filament recessed into the plug’s tip. When an electric current runs through the plug, or when exposed to the heat of the combustion chamber, the filament glows, enabling it to help ignite the special fuel used by these engines.
What does the low speed screw do?
The low-speed mixture screw is located in the end of the throttle shaft. The low speed mixture affects the idle quality and the low end engine power and throttle response. To check your low speed mixture setting, perform this simple test.
What voltage are RC glow plugs?
Most glow plugs require 12V, though some use other voltages. Make sure the engine is cold, and the glow plugs are turned off. Disconnect the power cable from the glow plugs. If you don’t do this, your tester will be powering all the glow plugs instead of just one.
Do you lean out the engine when flying with glow engines?
Once you have a glow engine running well and the needles set up properly, you really shouldnt have to fiddle too much with the needles each time you go flying. I notice that in cooler weather I may have to richen up the mixture, and in hot weather I slightly lean out the engine.
What is the best way to start a glow engine?
I find for smaller glow engines under a cubic inch displacement, an electric starter is a quicker and easier way to get an engine off and running for the initial runs. A chicken stick or a gloved hand is fine tooit may just take a little longer. Again, starters come in cordless and corded versions.
Can you break-in a glow plug engine in the plane?
If you can’t or don’t want to do a bench run, breaking-in your glow plug engine in the plane isn’t the end of the world by any means, and I’ve done it often enough. There’s no need to attach the wing, of course, and you can probably rig up some kind of temporary shield to steer the oily smoke away from the fuselage if needs be.
What kind of fuel is used in RC trainer planes?
Most IC (internal combustion) powered rc trainer airplanes take a 40 or 46 size glow plug engine that runs on a special blend of rc glow fuel, the ingredients of which are oil (either Castor, synthetic or a mix of both), methanol and nitromethane.
