Phewww Ultimatenewbie,
you’re asking a question about the main principle of flight
I’ll try to help you here.
It happens that I’m also an experimental aircraft (scale 1) pilot. So it helps me a lot to understand
how our models fly.
Do not try to remember all the principles I’m going to describe here. Just remember that flying has a lot of similar points
to see with bicycling (or motorcycles).
I hope I’ll be clear enough as my English is not as good as my mother tongue.
A) The torque effect.
This d**n torque effect
. Main law of forces : when something (anything) is turning clockwise the stuff holding it is willing to turn ANTI-clockwise.
See an helicopter ? When the main rotor is turning the fuselage WANTS to turn in the opposite way. That’s the reason why there’s a tail propeller on an heli.
This tail propeller compensates the torque effect of the main blade.
Let’s say the main rotor turns clockwise without the tail propeller the fuselage would turn the same speed and anti-clockwise. That wouldn’t be funny for the pilots ;D and pretty hard to fly straight.
This is the same story on an airplane : while the propeller turns clockwise the fuselage is willing to turn in the opposite way.
Two consequences to this issue :
1) That’s why a plane engine is mounted with a certain angle. If you remove the SC cowl you’ll see that the engine is not aligned with the fuselage (far from it
2) that’s also why it will always be easier while flying a plane to turn one way than the other.
ie : the super cub will turn easily on the left side and you’ll have to apply more strength on the right side. SO my advise for a beginner with the SC would be : always turn on the right
durong your first flights. It will allows you to be a bit rough on the stick without having to worry. When you feel comfortable with the right turns try easily to turn left (remembering that on the left side the plane will almost turn by itself).
IN THE END : this whole principle is of course proportional with throttle applied and the aircraft speed but this is easily understandable : driving a car at 2 mph obliges you to have large movement of the steering wheel while driving at 100 mph an inch is necessary to go out of the freeway
. The more speed the more the effect.
To answer precisely your initial question : NO the plane will not comes out of its turn automatically. You will have to “help” him to exit the turn by applying on the stick the opposite way of its turn (smoothly).
Another general principle is to remember that 80% of the time the plane flies by itself. Only applies some soft corrections. Just like a bike : you don’t have to apply forces on the bar all the time to keep on riding.
B) The centrifugal force
This one is the easiest to understand. Having a proper turn with an airplane is the combination of two elements : the lean angle (what we call in french the “incidence” I don’t know this word in English) combined with the direction (rudder).
Why a combination of these two elements ? : because if you apply only a lean angle, the plane will keep on flying on a straight line except the wing will not be parallel to the ground. And if you use only the direction (with the rudder) the plane will fly on a straight line but not in the axis of the fuselage (like a crab walking on the sand ;D).
Luckily for us, on a what we call “two channels” model the lean angle is controlled by the dihedral shape of the wing (the “V” shape of the wing). Advantage : for beginners like us you don’t have to worry about dealing with a third channel (that helps). The disadvantage: turns are less precise than with ailerons and you may forget about complex aerobatic. But first things first. One has to be comfortable enough before adding one more channel and having to manage a precise combination of incidence and direction. (imo of course ;-) )
This been said let’s go back to the bicycling image. If you ride fast enough and want to turn left (or right) one has to lean in the same direction as the turn (or you won’t turn and hit the wall
BUT if your speed is not high enough just try to lean and you will bite the dust for sure. Man this is EXACTLY the same story when you fly your model.
So when you’re having a turn with your plane always remember to maintain enough speed or you’ll fall like a rock.
BASIC PRINCIPLE : high speed = high incidence is ok / low speed = small incidence is ok.
For a complete beginner my advise would be : never have turns with more than 20 degrees angle. 45 degrees is hot… 90 degrees and you crash…
I will continue this post another time (I sometimes have to work ;D
I hope it helps.
