How to Set a Up Gas Engine RC Airplane?

A Gas Engine remote-controlled airplane is a complex piece of machinery. Capable of high-speed aerial maneuvers, your RC airplane needs proper setup in order to perform. If this is not properly done, the plane is doomed to a short life span capped by a crushing crash. The setup process requires you to place the components that operate the aircraft securely in the body of the plane and then to connect the components correctly. Once you've completed the setup process, your airplane should be ready for hours of trouble-free flight, limited only by your ability with the radio transmitter and not by the placement or connectivity of the airplane's components. Instructions 1, Place a single panel of plywood between the body of the aircraft and you engine mount to serve as a firewall from the heat of the engine. Glue the plywood in place using wood glue, taping it to the body overnight for the glue to completely dry. 2, Install an engine mount designed specifically for your chosen Airplane Model Engine to the front of the aircraft. Screw the engine mount into place using the plywood as an anchor for the screws. Place a layer of metal epoxy over the firewall and the nose of the aircraft to strengthen the plywood and to prevent fuel or oil spills from loosening the glue. 3, Mount the engine to the airplane by screwing it to the engine mount. Connect the exhaust system to the engine including the muffler, and then install the gas tank inside the body of your aircraft's fuselage, securing it in place with epoxy glue. Run a fuel line from the tank to the engine. 4, Install the electronics for your airplane. Place the electric speed controller and the radio receiver into the body of your airplane. Install the servos along the airplane fuselage, using double-sided tape to hold them in place. Follow the airplane manufacturer's instructions for servo placement location. Glue the control horns to the movable parts of the aircraft with the epoxy glue. Hook the pushrods between the arms on the remote control servos and the control horns on the various airplane parts each servo is meant to control. Test the moving parts by pushing on the servo arms to make sure the pushrods move the Engine Accessories. Plug the servos, and electric speed controller to the radio receiver, and then plug the engine into the electric speed controller. 5, Install the battery that powers the airplane's electronics system in the fuselage and mount the propeller to the engine, securing it with the propeller nut or nose cone.

Two Stroke Engine VS Four Stroke Engine

The distinctive features differ between two stroke engines and four stroke engines are the simple structure and few movement part. Two stroke engines have no air valve, and the structure can be simplified. Besides, two stroke engine operating need to ignition once a week (while four stroke rotation need ignition once in two weeks), and it has more explosive. Two characteristics make two stroke engine simple portable and low manufacturing cost. Main parts of the engine include: Crankshaft, connecting rod, piston and cylinder block. Crankshaft The function of the crankshaft is to turn a piston movement of up to down transfer moving in circular, and transfer the energy produced from the cylinder block burning used to rotational torque to pass out from the engine. Connecting rod The big head and little head of the connecting rod are divided to connect the crankshaft and piston. The piston Two stroke engine pistons can be designed as single or double loop. The main advantage of monocyclic design is that the frictional resistance is low, lightweight, large power, high speed and light vibration. While double loop design has more reliable sealing and long working lift, which has a slightly limit for stall. Cylinder block Cylinder bore parts can accommodate the piston, and the cylinder wall has an air inlet and outlet. The cylinder wall scavenging passage can lead the mixed gas from the bottom of the crankcase into the combustion chamber at the top of the cylinder block. What's more, the difference between the two stroke engine and four-stroke engine is the carburetor structure, two stroke engines are usually adopts the model of pump carburetor, and this structure can guarantee the normal work of the engine in all angles, especially suitable for flexible flip angles. So considering two stroke engines has simple structure, large power output and other characteristics of high speed, many hand-held power devices are chosen the two stroke engine as their power. But due to its own structural features, the two stroke engine's insufficient combustion, fuel consumption, noise and exhaust emission index is all higher than four stroke engines. European and American countries continuously introduce more stringent environmental regulations; also restrict the further promotion of two stroke engine products to come out in the market now. This kind of engine is just like its name, the two stroke engine including ascending and descending two working cycles. And it also contains two basic working principles: cross scavenging passage and loop scavenging passage. Loop scavenging passage is the most common form by far, the top of the piston can be flat or slightly convex. Generally, there are two cylinders scavenging passage in the inner vent, and the working principle and cross scavenging passage are similar, but the gas flow controlling is different. Two stroke engine working cycle Up trip Piston begins to move upward after passing the bottom dead center point, when go through the air inlet it will form certain vacuum negative pressure inside the crankcase, and then bring in fresh mixture of oil and gas from the carburetor to the crankcase. This process continued until the piston finished the upward stroke, and even due to suction gas inertia can be maintained to the piston top dead center. Before the piston reaches to the top dead center, mixed gas will be light in the ignited electrode spark. Explosive combustion pressure drives piston to do downward movement. Down trip When the piston downward exhausts outlet, the combustion gas will discharge from the vent. As the piston to continue downward, extruding the crankcase of inhaled gas mixture of oil and gas through scavenging passage to get into the combustion chamber at the top of the piston. After going past the bottom dead center, the piston begins to upward, close the scavenging passage and exhaust. The piston will continue upward to compression of the gas in the combustion chamber. Until now, the whole working cycle has finished. Air intake The compression Burning Exhaust Four stroke engine working cycle Two stroke engine pistons are doing the power trip every time after it got past the top dead center, while the four strokes engine does a power trip at every two weeks. In order to ensure the four schedules go smoothly, the airplane engine was designed with intake and exhaust door. The advantage of the four-stroke engine is that it can ensure efficient combustion at different rotation speed. Torque is bigger in low speed, due to it has increased structural components, the weight and complexity have also increased, but the structure principle of reliability has proved to be great in the practical for many years. Four-stroke engine working cycle starting from the intake stroke, when the piston downward to the bottom of the cylinder, inlet valve will open; the fuel air mixture was drawn from the carburetor to the cylinder block, until the inlet valve to close. During this trip, the valve kept being closed. Compression stroke Compression stroke is the second work schedule, starting from the piston moving up just after the bottom dead center, the exhaust valve to keep close and the inlet valve also closed at the same time. The piston upward compresses gas mixture in order to get the largest power. The greater compression, the bigger deflagration pressure after compression will have. And it has also done a function of preheat mixed gas and increases the efficiency of the combustion. Combustion stroke (power stroke) Combustion stroke is the third work cycle. The combustion chamber inlet valve and the exhaust valve closed, cylinder of compressed gas mixture of oil and gas was ignited by the Spark Plug electrode, and which will control the open and timely cooperate of the air valve. Exhaust stroke Finally stroke is the exhaust stroke, after that you have complete the entire work cycle. Share what you think about the two stroke engine and four stroke engine, and please stay tuned with us.

Getting to Know Nitro RC Engines

The generally called nitro engines are technically glow engines as they use glow plugs rather than spark plugs for electric engines. Nitro RC engines are suitable for powering a small sized RC airplane as large scale models are prefer to electric powered engines. Therefore, they are usually used in local flying filed. Compared with gas engines, they are less expensive and lighter; even cause less radio interference from ignition systems. As for noise, they are definitely silent than gas engines, while the fuel cost by them are over 10 times than gas engines. These engines use a special type of fuel that not only provides the energy for combustion, but also serves as a coolant and lubricant. Other than the plug and fuel, glow engines work the much the same way as any other internal combustion engine, but there are some distinct differences that are important to know. Nitro engines used for RC planes are usually 2-stroke or 4-stroke engines. A two-stroke RC engine fires every time the piston reaches the top of the cylinder while a four-stroke engine fires every other time. Four-stroke engines fire every other revolution which produces a very low pitched growl that sounds a lot like a full-scale airplane. That's why most large aerobatic and large scale aircrafts including warbirds use 4-stroke engines. http://www.agm-engine.com/getting-to-know-nitro-rc-engines-pd-251.html

How Does a Gasoline Engine Work?

• A gasoline engine works on the principle of combustion, the burning of a mixture of air and fuel inside the cylinders of the engine. Pistons compress the fuel and air inside your engine. Cylinders, located in the middle of your engine, are passageways that contain the pistons. When the pistons move down, the controlled explosion is transmitted to the engine crankshaft, moves through the driveshaft and onto the wheels of your vehicle. These elements are essential in making your vehicle run and your gasoline engine work.
  

Ignition

• Small ceramic diodes called spark plugs are attached to the cylinder walls. They ignite the compressed air and fuel inside the gasoline engine. This spark in the engine creates the combustion and gives your gasoline engine its power. Spark plugs work because they're connected to wires in the car's engine and are powered by an electrical current from your automobile's electrical system.
  

Power

• The controlled explosion gives your gasoline engine power. It's what makes it work. The gasoline engine works because it sends out power to the rest of your vehicle. The piston moves downward through the intake valve, letting in the fuel and air. When the piston comes back up, the fuel and air are compressed inside your engine. This happens every time the fuel and air are brought together.
  

How to Tune a RC Gas Engine?

Tuning the gas engine for radio controlled planes will ensure proper acceleration and keep top speed without harm the engine. Here are some useful tips for tuning your gas engine. Once knowing the working principles, this work will become much easier.
To distinguish a gas engine is out of tune or not, at first you should know about the working procedures of carburetor and other settings.
Actually, professional players may tell the tuned engines from others easily by observing the cycle status of engines. Most two cycle engines are unable to do "four cycle" works. The way to make it sound like a four stroke engine is by forcing the sparkplug to intermittently miss.
Normally it's inadvisable, while two stroke engines do have enough space to set. This can start the engine much easier and it need little or no warm up time during cold temperature. Thus the plane will fly preferentially by taking this advantage. This way will cause problems like:
1. The low end needle on a carburetor is always the closest one to the engine; while the high end needle is the closest one to the intake.
2. There is no fuel adjustment for idle fuel, only air feed set by the idle stop or servo.
3. Both the two ends needles offer the top end fuel supply.
So we still need to tune the carburetor to ensure normal operation.
First, adjust the smaller screw on the carburetor for low-end acceleration and idle. Turn to the left to enrich the gas mixture or to the right to reduce the mixture.
Second, adjust the larger screws of the two to left and right respectively. Tune to the right is to make the mixture reduce and for more speed; to the left aims to get a richer mixture and cool the running temperature.
Then, tighten the exhaust and intake manifold screws to make the engine start easier and won't die after a few times of running.
At last, remove the air filter and tighten the two bolts inside that go through your engine. They can hold the motor together and avoid air leaks as it may cause dying of starting.

AGM-30 Airplane Engine Troubleshoot Guide

This troubleshooting guide is for AGM-30 airplane model engine; in many ways, similar to those gas engines. If you have no spark or think you are having an engine problem, please contact your seller or manufacture for further help.
The following information will help you detect engine troubles and take corrective action.
Engine does not fire
If the engine fails to fire, the trouble can usually be traced to the battery, spark plug, or engine.
Ignition battery voltage low trouble generally occurs before the engine gets too low to perform the required work. The failure is normally preceded by charging or replacing battery.
Battery wires faulty or loose can deteriorate with age causing misfires, hard starting and poor performance. Wires should be replaced or reconnect.
Spark plugs, well, spark the combustion in your engine; it plays a vital role in keeping the engine running. If the spark plugs are all gunked-up or misfiring, the engine won't be running and starting properly. This can be done by removing the spark plug from the cylinder of the engine, inserting the plug onto the plug cap, and contacting the plug to the outside of the crankcase. Have an assistant turn the engine over while checking this and be sure to have the spark plug firmly plugged into the ignition wire.
Warning: The high voltage from the ignition can cause bodily harm, especially when checking for spark in this manner.

Symptom	Diagnosis	Solution
Engine does not fire	Ignition battery voltage low	Charge or replace battery
	Battery wires faulty or loose	Replace wires or Re-connect/check connections
	Faulty spark plug or not firing	Replace spark plug or check for spark.
	Engine flooded	Remove plug, disconnect fuel line, rotate prop to remove fuel
Engine starts then rpm increases till engine cuts out	Fuel not reaching engine	Check for: a) fuel in tank b) fuel tubing cut, blocked, or kinked c) carburetor clogged

Note: please always keep flames and sparks of all kinds away from the vicinity of storage batteries. In confined spaces this gas can form a dangerous explosive mixture.
When use your engine, you may encounter other problems that don't list above. The best way to identify and correct the cause of engine trouble is to think like a mechanic and use a systematic approach to problem solving.
