Pre-Flight Checklist for RC Airplanes, Safety First!
Safety First!
Pre-Flight checklists are very important in full scale airplaneflying, to ensure that pilots conduct a review of aircraft systems and or procedures prior to each flight. There are a zillion things that could go wrong during a flight. It is critical that you check everything humanly possible to minimize the risk of crashing your airplane.
The recent posts here are around the air plane, so this page today is contains a list of the most common Pre-flight checks for RC airplane. If you follow these checklist closely before each flight, you should be in good shape.
Frequency
If you’re flying at a club and have a 72 MHz radio system, you need to make sure that your frequency is free before turning on your radio! Follow your club’s pre-flight instructions for obtaining the frequency pin.
Radio Range Check
A range check is a very important pre-flight check that should be done before the first flight of each day at the flying field. Follow the procedure in your radio’s manual for doing a range check. Some radios require a slightly different procedure than others but all are similar to the following.
It’s helpful if someone holds the transmitter for you. Turn on thetransmitter, then the receiver. Leave the antenna fully collapsed. While holding the airplane, slowly walk away from the transmitter until the servos begin to twitch violently. With a PCM radio, the servos will stop moving all together. If this distance is farther than 100 ft then you are good to go! If it is less than 100ft do NOT fly! You must determine what the problem is and correct it before flying.
Check the Balance
Your should always balance your RC airplane before coming to the flying field. However, it is always a good idea to check the forward/backward balance one more time before the first flight of each day. Remember that the fuel tank must be empty when checking the balance.
Check the Bolts
The engine vibrations during flight sometimes cause bolts to vibrate loose. Make sure the bolts holding the wing to the fuselage are in place and are tight. Make sure all engine/motor mounting bolts are tight. Also make sure the propeller nut is tight.
Control Surfaces
With your radio system on, make sure the control surfaces are moving correctly with each stick movement of the transmitter. Make sure all control surfaces are secured firmly. Sometimes CA hinges can work themselves loose.Make sure all snap links are closed on the control horn clevises. You may also want to cut a small piece of fuel tubing to stretch over the snap link to keep it from coming apart in flight. Make sure all the servo horns and firmly attached to the control surfaces. Make sure the screw holding the servo horns to the servos are in place and tight.
Battery Levels
Make sure the voltage of the transmitter and receiver batteries are acceptable levels before flying. Follow the recommendations in the radio manual for minimum charge requirements. Failure to perform this pre-flight check before every flight could result in a pile of twisted balsa!
Engine
Be sure the engine is properly tuned before taking off. It’s a good idea to hold your airplane vertically with the nose upward while running your engine at full throttle to make sure it will run when in this position while in the air.Also make sure you hear the fuel clunk moving freely when shaking the airplane. Some times during a rough landing the fuel clunk can get flung towards the front of the tank and get stuck. This is sure to cause a dead stick landing.
Antenna Extended
Always double check to make sure your antenna is fully extended! It sound silly, but many times people actually forget to extend the antenna. Yep, I’ve even done it myself!
There Many RC club carry out their checklist to ensure safety, and some senior pilot will personally guide your flight, But just remember, anything could go wrong… The key is to expect the unexpected!
