The Controlled Aeration Port System is a BBLADES option that allows you to “custom tune” the aeration of your propeller blades – giving you the power to adjust the holeshot of your boat.
Just by varying the amount of aeration from the propeller ports and controlling your engine’s rpm, you can eliminate sluggish performance or compensate for changes in load and attitude when getting on plane.
On acceleration, exhaust is drawn out of the aeration ports. When the propeller blades strikes this aerated water, it pushes through it much easier than it would solid water – causing engine rpm to increase more rapidly. Once you’re on plane, the water externally flows over the aeration ports and seals in the exhaust, allowing the propeller to again operate in solid, non-aerated water. [links]
Now, hot glue the rectangular sections together to form a box and the triangular sections to form a triangular prism. Lastly, attach the two bodies together to complete the fuselage. more
Cut out a 1.2” by 5” piece from the balsa sheets. This will be glued to the bottom of the plane on the front. This allows a place to put weight(we used paperclips) in order to change the flight path if desired. here
Take the hook and insert it into the top of the fuselage right in front of the vertical stabilizer. The rubber band will be attached to this from the propellor.

The below image is of the CW and CCW of the DJI Mavic Pro quadcopter props. Both are marked with “8330F” which is the default props with come with the Mavic Pro. However, on the CW propeller it is actually marked as “8330F CW”. So it is good to look closely at your props to find out whether they are CW or CCW.
Most of the higher tech drones such as the Yuneec Q500 4k quadcopter allow you to fly it in 2 different ways. You can fly the drone as if you are the pilot and actually in the quadcopter. You use the control sticks differently on the roll whether the drone is coming towards you or flying away from you. more

Now, quadcopters use motor design and propeller direction for propulsion to basically control the force of gravity against the quadcopter.
In order for a quadcopter to rise into the air, a force must be created, which equals or exceeds the force of gravity. This is the basic idea behind aircraft lift, which comes down to controlling the upward and downward force.
Generally speaking, a prop with smaller diameter or pitch can spin faster (higher RPM), because the motor doesn’t need to work as hard to spin it so it pulls less current. They tend to run smoother and feels more responsive to the sticks. The faster change of RPM due to less inertia helps stability of the quadcopter.
A ship’s propellers create thrust in water in much the same way an airplane’s propellers create thrust in air. [links]
On a controllable-pitch propeller, the pitch of the entire blade can be altered during flight to give the best performance at different air speeds. This is similar to changing gears with a car or bicycle. [links]
Think of a propeller as a spinning wing. Like a wing, it produces lift, but in a forward direction—a force we refer to as thrust. Its rotary motion through the air creates a difference in air pressure between the front and back surfaces of its blades. In order for a propeller blade to spin, it usually needs the help of an engine.
Angle of attack is the angle a wing makes with the oncoming airflow. Pitch angle is the angle a propeller blade makes with its plane of rotation. A wing has nearly the same angle of attack across its entire length. But a propeller blade has a twist, so its pitch angle varies along its length. here
In cross section, a propeller is shaped like a wing to produce higher air pressure on one surface and lower air pressure on the other.
