Why does my RC helicopter not take off?
Why does my RC helicopter not take off?
If you have a fixed pitch RC helicopter that won’t lift off, the problem is not enough rotor speed. Some common things to check: Bad/weak battery (usually the most common culprit). Faulty motor (worn out, bearings shot, magnets shot, etc).
Why does my RC helicopter keep spinning?
A gyroscopic controller is used to coordinate the main and tail rotors so the helicopter can fly straight. When this system is not working correctly the helicopter will spin in circles. If the tail rotor blades are not pitched correctly they will not be able to hold the helicopter still.
How does a helicopter lift upwards off the ground?
This shape is called an airfoil. That shape makes air flow over the top faster than under the bottom. As a result, there is less air pressure on top of the wing; this causes suction and makes the wing move up. A helicopter’s rotor blades are wings and create lift.
How much weight can a RC helicopter lift?
It is around 36 grams. This means that the thrust should be around 0.48 Newtons. With the values from above, the maximum payload would be 12.9 grams. Of course, if this is the max payload for hovering, you won’t be able to lift off.
How do RC helicopters work?
Most RC helicopters make use of a handheld remote device with an antenna that sends signals to the helicopter’s IR receiver. The remote is generally a range from 3-5 channel RC Helicopter and can provide the methods of moving in the air depending on the number of channels that came with the remote control.
What is throttle hold for RC helicopters?
The throttle hold function will allow you to lock the engine throttle/speed at a pre-set value, usually idle or electric motor off while still having full control over the collective pitch using the combined throttle/collective stick. This function is usually activated by a toggle switch on your RC helicopter radio.
What happens if a helicopter flies too high?
What Happens If a Helicopter Flies Too High? As the helicopter ascends, the air begins to thin. With thinner air, the main rotor becomes less efficient. When the blades can no longer generate enough lift to keep ascending, the helicopter reaches its maximum operating envelope (the coffin corner).
