pre-flight test information | Pre-flight checks and safety protocol, electric RC helicopters | | Notes: The pre-flight test below is mainly for the beginner helicopters. The adjustments and tests are more complicated for advanced helicopters so we suggest customers get someone experienced for some help. | Step 1. Check the package. Check the helicopter is in good shape and make sure there is no part or accessory missing.
Step 2. Charging. For Ni-MH battery, it normally takes 1.5-2 hours to fully charge the battery and when the battery gets warm, please stop charging. For Li-po battery, it has the indicate lights on the charger to show the full-charge and it normally takes around 2.5 hours to fully charge the battery. When the battery is fully charged, do not leave it on the charger for long.
Step 3. Check the helicopter structure.
1. Make sure no part is missing, loose or apparent distortion, especially the parts between the rotor head and swash plate.
2. Check the main gear. The main gear and the motor gear cannot be too tight and normally the gap between them is 0.3-0.5mm. Turn the main gear by hand to see if it spins ok. Make sure the main gear is not loose from the main shaft and the motor gear.
3. Check the balance rod and balance blades. The balance rod cannot be distorted and the length must be the same at the both sides of the main shaft. The angles of the balance blades should be the same as well.
Step 4. Function test.
1. Install 8AA batteries for the transmitter, pull out the antenna, make sure both the throttle and throttle trim are at the minimum settings and turn on the transmitter.
2. Connect the battery to the helicopter. Make sure the C.G., center of gravity, is at the main shaft.
3. Don��t operate the throttle yet, but first operate the stick to see if the rudder, elevator, aileron works. The servo should response when you operate the stick, but the shake or abnormal sound of the servo is incorrect.
4. Hold the landing skid in one hand with a distance that the blades will not hurt you when they spin or it's recommended to have the helicopter held to the ground by weights or held to the ground by some other means and push the throttle gradually with other hand. Then the main blades will run. Push the throttle gradually to the maximum and the main blades rotating will gain the speed accordingly. Keep the maximum throttle for 10 seconds and see if the rotation of the main blades and tail blades run correctly and make sure there is not abnormal sound or smell in this process. Then pull and push the throttle repeatedly for around one minute to make sure the motor will not have the problem to stop working suddenly. (For some helicopters, you need to press the start button on the ESC to begin the control of the main blades.)
Step 5. If you are new at RC helicopters, we suggest you get some help from someone experienced in order to avoid some unnecessary damage due to improper operations. Enjoy your flight! | | | Pre-flight checks and safety protocol, Nitro alcohol engines. Fixed wing aircraft | Step 1. Check the plane structure to make sure there is no distortion or loose part in the fuselage, wings, rudder, elevator, aileron, etc.
Step 2. Make sure your engine is running properly by setting the throttle needle valve to obtain full power. Make sure not to run the engine to lean, usually obtained full RPM and then turn the needle valve a little richer about a quarter of a turn. This will compensate for altitude and leaning out as the fuel becomes lower.
Step 3. Make sure the engine idols properly.
Step 4. Make sure elevator ailerons and rudder are moving in the proper directions and moving freely.
Step 5. You must make sure you do a radio range check with the engine running and airplane held in place by a helper or some other means. Put your radio antenna down to its lowest position and walk away from the aircraft 50 or 60 feet. Making sure the flight control surfaces and engine are controlled reliably. Put your antenna up if this test passes. Your range will increase dramatically when your antenna is up, you should do this test once every time you go to the flight field.
Step 6. Make sure your fuel is full you are now ready to launch. Enjoy your flight! | | | Pre-flight checks and safety protocol, electric motors. Fixed wing aircraft | Step 1. Check the plane structure to make sure there is no distortion or loose part in the fuselage, wings, rudder, elevator, aileron, etc.
Step 2. Make sure your motor is running properly and your battery is fully charged.
Step 3. Make sure elevator ailerons and rudder are moving in the proper directions and moving freely.
Step 4. You must make sure you do a radio range check with the motor running and airplane held in place by a helper or some other means. Put your radio antenna down to its lowest position and walk away from the aircraft 50 or 60 feet. Making sure the flight control surfaces and motor are controlled reliably.
