Remote Control Helicopter Knowledge - Beginner Q & A (part 3)

Q: Why does the RC Helicopter shift to the left or other direction when it takes off, rather than take off straight?

A: Due to the gyroscopic effect and the influence of main jet airflow, it is normal for a RC Helicopter to lean to the left on takeoff! You need to push the aileron stick slightly to the right. If the helicopter is offset in the other direction it can be corrected by fine tuning when it is on the ground.

Q: What is hovering? why do I need to practice hovering?

A: Hovering is that the RC Helicopter is almost stationary in the air somewhere in a certain height, which is other RC aircraft can not complete! For starters, you must start with a hover flight practice for some times since the helicopter's takeoff and landing, as well as some other start and end of a flight, require a hover flight first.

Q: What is pitch?

A: Pitch refers to the RC Helicopter rotor or fixed-wing propeller 360-degree rotation, the distance of the helicopter to move up or forward. The greater the pitch, the greater the distance, and vice versa. However, it is difficult to measure the actual pitch. The vast majority of fixed-pitch helicopters are generally custom-made for a certain model, so the diameter is indicated. Variable pitch helicopters can measure the windward angle of the rc helicopter blades and the magnitude of change to know the pitch.

Q: What is D / R?

A: D / R is Dual Rates, which is used to adjust the maximum stroke of the end of each channel. However, unlike the EPA, D / R has only one setpoint, so it acts on both ends and is bidirectional symmetrically. The D / R function can switch different parameter values through a dedicated D / R switch, which is generally used to switch the control of the size rudder to adapt to the different requirements of the model on the rudder movements when different flight requirements are required.

Remote Control Helicopter Knowledge - Beginner Q & A (part 2)

Q: When the RC Helicopter is beyond the remote control range, will it lost?

A: If your remote control is out Pfizer power, do not worry, because some remote control has the  protection switch, that is, when your helicopter can not receive your remote control signal, the RC Helicopter can remain the last action, or automatically restored to the appropriate pitch and speed, so that it will land in low-speed. But if you want the RC Helicopter to fly back, it is almost not possible to complete. That is why we have always stressed that the novice must fly within the controllable visual range.

Q: How much weight can RC Helicopter load?

A: Under normal circumstances, 30-level RC Helicopter can carry about 1.5 kg, 90-level RC Helicopter, after adjustment, can carry about 3.5 kilograms. So you should trust your rc heli parts is strong enough.

Q: How long will the receiver's battery be used for one time?

A: The original 1600 mAh battery pack and rc battery cables, after a full charge, can be used continuously for 4-5 hours or so. But usually, the players will take a rest for a certain time after flying half an hour. 5 hours of continuous flight will be very tired. 

Q: What is the target crowd?

A: Many people will buy an rc helicopter toys for their children which in fact, might be not that necessary. Professional RC Helicopter model has a lot of complex structure, unless under the help of adults, otherwise, the children simply can not understand. On average, players are the 40-year-old middle-income earner, as the costs of RC Helicopter is not cheap, from a few hundred dollars to several thousand dollars. 

Q: What are the climate requirements? Wind resistant?

A: Heavy rain, thunderstorm weather is absolutely not suitable. As the RC Helicopter has an electric or oil-powered motor, the wind-resistant ability is strong. At the same time, the larger the level of the RC Helicopter, the stronger the wind resistance and stability. Therefore, in addition to rainy weather, windy weather, in general, are safe to fly.

Q: What is RTF?

A: The professional RC Helicopter model is in the sale form of host and scattered RC Helicopter accessories. This is more convenient for players to DIY assembly according to their own requirements. Therefore, there will be the different performance of the different accessories of the helicopter exists. RTF means Ready To Fly, that is, all the assembly is good, debugging is good, all the equipment, including remote control, is set so the rc helicopter rtf version can be used to fly the moment you get it.

Q: The composition and main parts of the remote control helicopter

A: The main components of the helicopter is the host, the electronic equipment, and remote control.

The mainframe includes: rack, dial disk, main rotor chuck and arm pull components, tail rod components, and tail boat group.

Other RC Helicopter Parts include: 3 swashplate steering gear, a standard throttle servo, a lock tail gyroscope and a lock tail steering gear, the main motor for high-energy batteries, electronic governor, 2 in 1 buck Device, receiver, transmitter and other remote control helicopter parts.

Q: How high can an RC Helicopter fly?

A: Theoretically, as long as there is power, when the air and pitch angle greater than 6 degrees, the helicopter can rise in an unlimited way. The professional model used remote control can reach the remote control distance of 400 meters -1500 meters range. When the helicopter flew to 300 meters away from us, it is already very small, it can be said that the flight distance has exceeded the visual distance. Therefore, generally, no need to worry about height.

Q: How fast can an RC Helicopter fly?

A: There is no accurate data. But the speed of 80 kilometers per hour is fully guaranteed. When the power is sufficient, the distance of 200 meters just in a few seconds.

Q: When the RC Helicopter starts, will the main rotor turn? How to turn off?

A: The RC Helicopter has been tested for many times so as long as the player is in accordance with the normal start step, the main rotor will not hurt the fingers. After the start of, the RC Helicopter is at a low speed, we push the take-off bar, the engine becomes high speed, then the main rotor will turn. After the plane landed, returned to the idle state, there is a switch on the left side of the throttle, pull down to turn off.
