Why do RC helicopters have 2 fans?
RC (radio-controlled) helicopters have two fans for a variety of reasons. The most important reason is that two fans provide more lift than a single fan. This is because two fans increase the total amount of air that is pushed through the rotor blades, creating more lift. Additionally, two fans provide more stability to the helicopter, as they can be adjusted to provide different amounts of thrust in different directions. This allows the helicopter to remain stable in flight, even when there are changes in wind direction or speed.
Another reason why RC helicopters have two fans is that they provide redundancy. If one fan fails, the other can still provide enough lift to keep the helicopter in the air. This is especially important for larger helicopters, as they require more lift to stay in the air. Having two fans also allows for a greater range of speeds, as the fans can be adjusted to provide different amounts of thrust depending on the situation.
Finally, two fans provide more power for the helicopter. This is because two fans can generate more power than a single fan, allowing the helicopter to reach higher speeds and climb to greater heights. This is especially important for larger helicopters, as they require more power to stay in the air.
In conclusion, RC helicopters have two fans for a variety of reasons. Two fans provide more lift and stability, redundancy, and more power for the helicopter. This allows the helicopter to remain stable in flight, reach higher speeds and climb to greater heights, and remain in the air even if one fan fails.
Comments / Question
2. Use a flybar: A flybar helps to dampen the oscillations of the rotors, making the helicopter more stable and reducing the risk of a crash.
3. Use a gyroscope: A gyroscope helps to keep the helicopter level and stable, reducing the risk of a crash.
4. Use a governor: A governor helps to keep the rotor speed constant, reducing the risk of an out of control situation.
5. Use a low voltage alarm: A low voltage alarm will alert the pilot if the battery is running low, allowing them to land the helicopter safely.
2. Increase the power of the motor. Increasing the power of the motor will increase the torque generated by the motor, allowing the helicopter to fly faster and with more agility.
2. Increased airspeed: Two fans running at the same time can create a higher airspeed, which is beneficial for aerodynamic performance.
3. Increased lift capacity: More air circulation means more lift, allowing the helicopter to carry heavier payloads.
4. Balance: Using two fans in opposite directions allows the helicopter to stay balanced in flight.
5. Versatility: Having two fans allows for greater control and maneuverability when flying an RC helicopter.
