Essential use of the Model aircraf gasoline engines

1, Run-in operation - all new engines must lower speed to a stage of operation, the time from half an hour to one hour or more, known as the run-in operation (grinding car). Very important operation, run-run-in operation is not good, the engine is not only the short life and small horsepower, it is difficult to start, but also bring a lot of failure. The said mill car useless, vain losses are one-sided understanding of gasoline engines and other. The correct operation of the run-in will never shorten the life of the engine, on the contrary will extend the life and improve performance. That new cars and motorcycles, for example, limit the speed of the plug is equipped with carburetor factory, or requiring speed should not exceed a certain limit, after traveling hundreds of kilometers before gradually increase the speed to run-various parts.

Steps as below:

The oil line parking off quickly after just grinding the car, the engine running for 1 to 2 minutes, until the engine cool slightly and then drove, do not continuous operate for a long time. Doing so, is also conducive familiar with this engine to start and adjust. Then, first at low speed for 20 to 30 minutes, if the cylinder head is not too hot (fingers on 1 to 2 seconds can tolerate), uniform speed can be slightly pressed regulator lever off smaller needle, improve a little speed. Continue mill car about 20 minutes. Replaced with a smaller propeller, and gradually increase the speed. Finally, turn to the propeller of the flying model, high-speed mill car 10 to 20 minutes.

The black oil may spray from the exhaust when the new gasoline engine just grinding. Finger extensor near the exhaust port, and will be sprayed with a layer of oil from the reservoir in the sun to see the glittering metal powder. Generally, to grind the car for half an hour, the black oil would greatly reduce or eliminate. Should gradually improve the speed, as the speed has been stable and the phenomenon of "heat death", grinding the car comes to a close, the engine installed in the model aircraft. Each engine requires grinding car insufficiency and the same time, to be determined according to the specific circumstances. Usually it’s about one hour.

After correct mill car on the small gasoline engine, it would have a good airtightness, easily started, easily and flexibly rotated, even if the continuous high-speed operation, the rotational speed is not changed (can be judged from the sound).

2. Installation - compression-ignition engine can be used as a power plant in the aviation, marine and land-based model. When used on a model airplane, it can be mounted in the nose front (pulled into formula), which is generally the most common patterns; also be mounted on the tail and other parts (push), then must be made after the paddle pad and the distance between the receiver front end face is less than the distance between the crank pin and the casing rear cover, so that after the passage of the propeller thrust paddle pad passed to the receiver end surface friction, not to the crank pin and the rear cover.

Small RC engine can be set up upright (cylinder head on), upside down (Cylinder head next) and transverse loading (toward the side of the cylinder head). The most common is the upright and transverse mounted. upside down starter is more difficult, and prone to oil and more. On-line manipulation of the model, especially on the control line stunt model in order to protect the engine, often with transverse mounted. Transverse engine is still a good start.

Small rc engine in practical applications, the problem may appear as well. So we need to often analysis, find out the reason, sum up the experience through practice.

3. maintain;

(1) keep the engine clean inside and outside, and never let the dus, paper, sawdust or other dirt from entering the internal. Engine when not, use a clean cloth or paper. After each use or flying, use clean paper or cloth to wipe them off of the engine outside and package; same time with a little gasoline or kerosene cloth to wipe off the oil on the model aircraft, with a dry cloth net. Do not drive much dust or sand on the ground or take-off; forced to take off in the sand on the ground, poured some water or pad some thick paper and wood to prevent sand from entering the engine. Do model airplanes often need to use the engine measuring the position and size of the intake and exhaust ports of the engine should be wrapped to prevent paper wood chips and other dirt from entering.
(2) Take care of the engine. Non-essential, do not use high-speed continuous drive, or use excessive short propeller and flywheel car. The regulator lever overextended.
(3) as much as possible not to dismantle or less demolished engine.
(4) To choose the right tools, the right propeller, the right ingredients and clean fuel.
(5) To contact with the rc engine oiling appliances often, tools and model aircraft to be kept clean. Should be ready a clean the locket specifically bloom oiling appliances, and Do not oiling appliances anywhere misplacing, so as not to the lime soil as the oiling enter engine. Lime soil as abrasives will quickly wear out the engine. Best the oiling of appliances, box, lecythus, and wrench on a specially prepared cloth or wooden box. Both convenient to use, but also to ensure cleaner, forgot some necessary tools to avoid going out flying.
4, Note safety - model aircraft engines, although very small, but the speed is high. Therefore, we should pay attention to safety, to prevent accidents.

After starting, do not stand in the plane of rotation of the propeller. Cannot use cracked or broken propeller goes for some and unbalanced, broken propeller decision cannot re-use gel. Never use metal propeller.

Do not close to high temperature or fire place when store the oil. Preparation of mixed oil and cleaning with gasoline engines, absolutely cannot smoke, and prevent smoking people closing. Do not open the rc engine indoors as much as possible to avoid the inhalation of ether and exhaust. Mixed lecythus outside must be marked toxic, so as to avoid misuse.Now i have told about many things aboutthe use of the rc gasoline engine and maybe you can see some of them from the online shop and sellers always write the use information in the production page. but i also hope it can give you some helps.
