RCGF will not be responsible for any safety issues or accidents involving this engine. ● Operate the engine in a properly ventilated area. ● Before starting the engine, please make sure all components including the propeller and the engine mount are secure and tight.
engine life. Synthetic 2-cycle oils leave fewer combustion byproducts than natural oil which can foul the engine and exhaust ports, resulting in reduced performance. Synthetic oils also reduce friction and provide more fluidity at low temperatures. ● Do not install your throttle servo or kill switch servo inside the engine compartment. Doing so could cause radio interference. Install all electronic radio devices as far away from the engine as possible.
Before beginning installation it’s a good idea to plan location of the various components of the engine. Many of the following steps may need to be completed in a different order than listed. 1. Check to see that all screws and bolts are tight. Check carefully for any cracks, broken, or missing parts. Tighten or replace any damaged or missing parts before proceeding. 2.
3. Connect the kill switch lead to the red connector from the ignition control module using the lead from the kill switch or with the included three pin connector with pig tail. Use one of the included three pin securing clips to secure the connection. 4. Connect the ignition module battery to the kill switch. Any 4.8-6.0V, 1000mAh and above capacity battery will work well for this.Use heat shrink tubing to secure this connection. 5.
9. Install the spark plug into the engine head (6-9lbs torque). Installing the RCGF 10cc on Your Airplane Note: The RCGF 10cc must be installed on at least a 6mm [1/4‖] firewall. The firewall must be securely glued to the airplane. Use triangle stock and pin the firewall with hardwood dowels to reinforce the firewall glue joints. Never install the RCGF 10cc onto a firewall thinner than specified because it may fail due to the power of the engine.
to be used as fill line. Installing a third line is the cleanest and easiest way to add fuel. An alternative fueling set up is a 2-line system with a T-fitting approved for gasoline use. Be sure to use a filler plug with either a 2 line or 3 line set-up. It is a good idea to add an extension to the vent line as shown, that goes up and to the rear of the tank. This helps to avoid draining fuel from the tank when the model is pointed down. 7. Install the throttle servo as far as possible from the engine.
8. Connect the ignition wire from the ignition module to the spark plug. 9. Install the muffler onto the engine. Be sure to use threadlocker and that the ignition wire does not contact the muffler. 10. Cut all necessary clearance, carburetor adjustment, cooling, and exhaust holes in the cowl. A 1:3 ratio of airflow intake area to airflow exhaust area is recommended for proper engine cooling. 11.
Install the Propeller 1. It is recommended that you test-run, tune, and break-in the engine before flying. To make this easier we recommend that you remove the cowling. 2. Set the engine near the beginning of the compression stroke. Note the position of the ignition magnet with the engine inverted.
3. Place the spinner back plate on the engine and the propeller on the crankshaft at the one o’clock position. 4. Install the prop washer on the crankshaft. 5. Install the spinner cone. Be sure to use thread locker on the spinner bolt.
Adjustment of the Engine Each RCGF Engine has been factory preset. However, differences in elevation will influence the performance of the carburetor. To obtain optimum output of the engine, slight adjustment of the carburetor may be necessary. Engine Functions and Adjustments The 10cc carburetor is specially designed according to the engine. The fuel pump and carbuertor is seperate . And the low-speed needle and high speed needle are designed in one needle.
1. Throttle 2. Adjustment speed needle (Low-speed Needle and High-speed Needle) 3.fuel pump—connect to carburetor , oil inlet 4, fuel pump—connect to carburetor ,oil outle Idle Adjustment Adjust the throttle and speed-needle to adjust the idle speed. Speed Needle Adjustment (Including high-speed needle and low-speed needle) The default or factory setting of the Low-speed Needle is as follows: turn the needle to the fully stop/closed position and then turn back 2 and 1/3 turns.
Carburetor Adjustment Troubleshooting Problem: If The engine hesitates when accelerated rapidly.or The rpm increases at idling. or The engine stops when the throttle is moved from high to low. Solution: The low-speed needle ―L ‖ is too lean. Open it up about 1/8 of a turn and try again. Problem: If The idle is not steady. Solution: The low-speed needle ―L ‖ valve is too rich. Close it 1/8 of a turn and try again. Problem: If Engine stops at full throttle. Or Engine hesitates when accelerated rapidly.
the beginning of the compression stroke so that it’s comfortable to flip it through compression. 2. Have someone help you hold the airplane while you start the engine. 3. Switch the ignition to ON, open the throttle slightly from the idle position. 4. Flip the propeller counter clockwise several times briskly, until a popping sound is heard. This indicates that the engine is firing. 5 Set the throttle to a high idle. Set the propeller so that it is at the beginning of the compression stroke.
Faulty spark plug or not firing Engine flooded Engine starts,then rpm Increases till engine cuts Fuel not reaching out engine Replace spark plug or check for spark Remove plug, disconnect fuel line, rotate prop to remove fuel Check for: a) fuel in tank b) fuel tubing cut, blocked, or kinked c) carburetor clogged This can be done by removing the spark plug from the cylinder and attaching the plug on the outside of the crankcase.
Tachometer. If your ignition module does not have this additional lead, the Digital Tachometer can still be used. Simply use the Y-harness (included with the Digital Tachometer) to connect to the pick-up lead from the engine. Be sure to secure all connections and to secure the Digital Tachometer or leads on the aircraft used. RCGF 8.4 V Ignition modules use the Digital Tachometer Engine Maintenance Please clean the fuel filter in the RCGF Carburetor periodically.
