The difference large hole blade VS Small hole Blade

The Root of large hole paddle is thick, high-speed rotation distortion, suitable for high-speed high-torque motor, heavy weight, suitable for large aircraft. While small Hole paddle roots thin, soft and easily deformed, and lightweight, suitable for small aircraft with a wingspan.


Coaxial Tail Rotor Review (2)

Tail Drift: Tail drift makes sense when you realize one thing about vertical tail rotor: it is in all ways similar to the rotor blade of a single-rotor heli, RC or real. Thus, it creates a torque effect when it spins, just as a real heli’s rotor blades do. However, unlike a single-rotor heli, it …Continue reading


Coaxial Tail Rotor Review (1)

Tail Lift: Tail lift at first seems obvious, but on closer look it is actually quite interesting. When a forward command is initiated, you’ll recall from my forward flight section on Coaxial Quirks that the tail rotor creates lift on the tail, right? Well, when the main rotors are spinning fast enough to enable a …Continue reading


How to Balance Blade (4)

Other things to consider Before you do balance a propeller, measure the distance from the inside of the hole to the tip of each blade. The distances should be equal. If there’s a inconsistent between the two measurements (if there is, it shouldn’t be much), carefully sand back the longer blade until both sides measure …Continue reading


How to balance Blade (3)

The alternative method, especially on small diameter propellers, is to leave the hub as it is and balance the blades. You can either add weight to the lighter blade, or remove weight from the heavier one. To add weight to a lighter blade, tape can be added to the back side of the blade. This …Continue reading


How to balance Blade (2)

Step 2: once you’ve determined that there is a difference in weight between each side of the prop, there are two ways you can attack the problem… One is to balance the hub of the prop. This method is better for props of, say, 8″ and upwards. Anything smaller and the job gets a bit …Continue reading


How to balance a blade (1)

A perfectly balanced rc Blade will mean less vibration in your plane and this is very beneficial – severe vibration can cause weaknesses and failures over time, not just in the airframe but also the electronic components of the plane. For the short time it takes to correctly balance a prop, the rewards are large! …Continue reading


FPV LCD Display VS FPV Goggles (2)

FPV Goggles usually are most FPV pilot’s first & favorite choice. Good video FPV goggles completely block out any sunlight from entering into the nice soft eye cups and completely immerse you into the image and flight experience. It’s not complete edge to edge total image immersion, it’s more like looking at a big screen …Continue reading


FPV LCD Display VS FPV Goggles (1)

Most FPV displays are simple and small 7″ to 10″ LCD FPV monitor. They are portable, light weight, will generally run fine off the power from a 3S LiPo battery, and easy to hook up to the video receiver through RCA type AV cables. The advantages to displays over video goggles is several people can …Continue reading
