How do I choose an RC plane propeller?
If choosing a three or four bladed propeller over a two bladed one, a very general rule of thumb is to decrease the prop diameter by an inch and increase the pitch by an inch. That said, fuselage and ground clearance issues might dictate which propeller size you can and can’t have on your plane.
What is propeller in RC plane?
Scale RC aircraft propellers are usually specified as diameter × pitch, given in inches. For example, a 5×3 propeller has a diameter of 5 inches, and a pitch of 3 inches. The pitch is the distance that the propeller would advance if turned through one revolution in a solid medium.
How do I choose a RC electric motor and propeller for my plane?
The kv of your motor is the number of revolutions per minute it will spin per volt. The lower the kv, the stronger the motor and as a result, you will want a larger propeller for maximum thrust. Often slower motors will also result in slower flying planes, a big plus for your first hobby grade rc plane.
What is an 8060 propeller?
8060 paddle is the newest material to make the high efficiency propeller, the new mold, the material, the blade is adjusted, the performance is better than the old style, solves the old prop break problem. Pitch : 152mm / 6″;Max Thickness : 10mm / 0.39″
What is the difference between a 2 blade and 3 blade prop?
A 2-blade propeller produces two pressure pulses per revolution, whereas a 3-blade propeller will produce three smaller pulses per revolution for the same amount of total thrust. As a result, the 3-blade prop will be inherently smoother and therefore quieter.
What is the difference between a 2-blade and 3 blade prop?
How much thrust do I need RC plane?
You need a 7.5Kg thrust at 100% throttle, more than enough to fly your aircraft. Post installation of your BLDC, you shouldn’t change your all up weight. For Fixed wing you need a thrust of about 70 – 80% from your all up weight.
How do I know what pitch prop I need?
A lower pitched propeller will create more power due to more engine RPMs, but the boat will move slower. A higher pitched prop allows the boat to move faster by travelling a farther distance with each rotation. When choosing a propeller, choose a pitch that will keep the engine RPM in its recommended operating range.
What kind of propellers are used in RC aircraft?
High performance and efficient Model RC Airplane Propellers for Gas, Electric and Glow Engines made of Beechwood, Laminated, Carbon Fiber and Composite. Our Model RC Aircraft Props Line includes Beechwood Sport Props, Pusher, 3D Fly, F3A Competition, and Custom Designs like the “War Bird Series” WW1 & WW2 style Props .
Why do airplane propellers have a profile airfoil?
The prop’s job is to convert the engine power in to thrust, to pull/push the plane through the air. Thrust is generated in exactly the same way as lift is generated by the wing, and that’s why props have a profile airfoil section.
How big of a propeller do you need for an airplane?
The diameter of the propeller (10″ in the example above) will also effect how the airplane flies, but also how the engine runs and, again, following your engine manufacturer’s recommendations is the place to start.
Why is propeller selection important in electric airplane?
But with the advent of electric power (EP), propeller selection became a whole new minefield! EP prop selection is much more critical because different combinations of motors, ESCs and battery packs can generate huge differences in operating speeds and loads.
