Paper folding method for DC-3 aircraft
The DC-3 is the perfect paper airplane for an American player, with adjustable ailerons and tail, and has won several design awards.
Before we roll out the paper plane, it should be scrutinized just as carefully as the real plane is before it takes off. Note that the two wings must be mirror images of each other. If the two wings are different in height or the tail is bent, both can cause the paper plane to underperform. So after checking out the problem we need a careful correction.
Paper planes can be thrown either hard or gently. On a windy day, toss the paper plane against the breeze and it will flip over for a few seconds, and after tumbling over again, it can fly a long distance with the wind. On a windless day we need to toss it gently along the horizontal and it will glide for a long time with a slightly curved trajectory, but overall it should be straight.
Suppose we find a trajectory to the left or right. It can be corrected by adjusting the wing. The practice is to cut out the aileron on the wing and fold the aileron up or down. We can also change the upward folds on the left and right sides of the wing to downward folds.
If the plane is a bit head-over-heels, we can try to get the tail up a bit. Note that all adjustments must be made in small increments and should be test flown immediately after the change to observe the effect.
According to the experts, at least the following principles should be observed in the design of paper aircraft for smooth flight:
The heavy front end design ensures flight stability, and the nose is secured with paper clips that allow the aircraft to fly farther.
If the aircraft is overweight due to the nose, adjust the tail end of the wing and slightly fold it upwards.
The center of gravity should be forward to prevent the aircraft from swaying.
According to experts, the ideal center of gravity should be located about one-third of the fuselage from the nose.
The wings should be angled upwards so that the aircraft is seen in a “Y” shape from the front.
A small wing tip helps to reduce flight drag.
Look down at the front of the aircraft, check for symmetry and refold if necessary; complete asymmetry will not achieve smooth flight.
Patience and fine-tuning are more important than radically changing the basic design.
