How to Fly Airplane







Learn to Fly Airplanes
You can learn how to fly fast if you choose the right airplane and follow a few suggestions!
You can learn how to fly RC airplane instantly, avoid unnecessary damages and enjoy flying once you follow rules below. You don?t need an instructor if you choose the right airplane to start with.
1. Make clear how an airplane flies. Here?s how airplanes fly: When the wing moves forward the air lifts it. Too slow, no lift and it falls out of the air -- it stalls. So, it needs flying SPEED either from a motor and propeller, or by descending and gliding. The wing is lifting all the time it's moving forward -- whether it?s upside down, in a turn, inverted, or doing aerobatics -- there is always lift from the wing even though the lift might not be straight UP as it is in level fly. The airplane makes right or left turns by tilting in the direction of the turn so that some of the wing?s lift is angled partly to the left or right. To turn an airplane you tilt the wings with the ailerons or with the rudder in the direction you want to turn. To make the airplane go UP you give an UP command to the elevator. The elevator surface angles UP and the air that?s hitting it blows the tail DOWN and the nose UP. When the airplane goes UP it slows down. If it goes too slow the lift stops and the airplane falls -- stalls.

2. Choose an airplane that can fly all by itself without your controlling. Don?t pick a low-wing, aerobatic airplane. The best choices are slowflyers, parkflyers, or gliders that use electric motors for power. Gliders can glide straight ahead all by themselves (if they do not have a warped wing -- see below) without you doing any controlling from the radio transmitter. If you want to fly without an instructor these glider type airplanes will fly themselves while you are trying to figure out how to make them go some other direction. You need this stability while you learn how to fly. The second best choice is a non-glider (powered airplane) that has the wing on the top of the fuselage and which is advertised to be a good training airplane.

3. Confirm that these following things are correct before each fly:
A. The balance point MT be where the airplane?s designer intended. Don?t be afraid to add lead weights to either the nose or the tail to make the airplane balance where it is supposed.
B. The wing mt not be warped,. Fasten the wing onto the airplane. Set the airplane on a table and walk off to the rear of it. Look back at the airplane from an eye position where you can see Just a bit of the BOTTOM of the entire wing. If you see MORE bottom wing surface on, let?s say, the left wing, then your airplane will tend to turn left even when you have the aileron or rudder control in neutral. Remove that warp before you try to fly the airplane.
C.The wing should have something called "washout""Washout", this is an intentional and desirable warp of the wing near each wing tip. ually this warp is done to the outer 20% of the wing toward each wing tip. From the rear of the airplane you should see a little more of the BOTTOM of the wing near both wing tips. Why is this "washout" good? It helps the outer parts of the wing continue flying straight ahead during the beginning of a stall. This means that your airplane will stall straight ahead instead of rolling over on its back or side when it stalls and that rolling over might be impossible to recover from.

4. Find a BIG flying field for your first flys. Don't try to fly in your street even if the airplane is capable of flying in such a restricted area. You will need lots of open and unobstructed space for your first flys.

5. Properly take off
A.If you hand launch your airplane throw it hard and throw it straight ahead, not up.
B. If you take off from a ground roll let the airplane build up so much speed on the ground before you signal "UP" elevator, that you KNOW that the airplane has enough speed to fly. When it leaves the ground try to climb at a very small angle, not abruptly upwards which could CAUSE loss of airspeed and a stall.
C. Give very little UP elevator as your airplane starts to take off. Most beginning modelers try to climb too steeply which makes their airplane slow down, stall, then crash.

6. How to control turn during fly
A. You turn an airplane differently than a car or a boat: when you tilt the airplane?s wing in the direction that you want it to turn, the airplane will continue to turn as long as the wing is tilted in that direction. But you will NOT be holding the control stick in the direction of the turn (as you would on the steering wheel of a car) -- you will have the control stick near NEUTRAL during the turn. To STOP the airplane from turning you move the control stick in the opposite direction from the turn so that the wings level out. "Beginner's" airplanes have a built-in tendency to automatically come back to level fly if you let go of the control stick.
B. Don?t try any turns until the airplane is very high. Mostly climb straight ahead with only gentle turns.
C. Practice gentle turns high in the air before you try to land. Practice "landings" while high in the air so you get a good idea of the airplane's stalling (fall-out-of-the-sky) speed. If the airplane stalls Just give a bit of DOWN elevator and the airplane will be flying again.
D. avoid turns when the airplane is low.

7. Don?t try to land in a specific spot, Just let your airplane glide into the ground straight ahead. The bigger the field for your first fly, the greater will be your chances for success.Hope you can enjoy yourself with your rc plane!
