A 3-channel remote control is generally better for an RC helicopter because it allows for more precise control and maneuverability. With a 3-channel remote, you can control the throttle, yaw, and pitch of the helicopter, giving you more options for flying and performing tricks. A 2-channel remote control may be simpler and easier for beginners to use, but it limits the helicopter's capabilities and may not provide as much control. **

The person who knows this remote control is likely the owner or someone who has been given permission to use it. They would be familiar with its functions, how to operate it, and where it is usually kept. It could also be someone who has been trained to use the remote control for a specific purpose, such as a technician or a staff member in charge of operating a particular device. **

To control a receiver with a universal remote control, you first need to ensure that the universal remote is compatible with the receiver model. Then, you can program the universal remote by following the manufacturer's instructions, which typically involve entering a specific code for the receiver. Once the universal remote is programmed, you can use it to control the receiver by selecting the appropriate device mode (e.g., TV, DVD, AUX) and inputting the desired commands. **

There could be several reasons why the remote-controlled helicopter is not rising anymore. It could be due to a drained or malfunctioning battery, a damaged rotor or motor, or a problem with the remote control signal. It's also possible that there is an issue with the helicopter's internal components or wiring. It would be best to troubleshoot and inspect the helicopter to determine the exact cause of the issue. **

The problem with the remote-controlled helicopter is that it is difficult to control and keep stable in the air. The helicopter seems to veer off course easily and is hard to maneuver precisely. Additionally, the battery life is short, limiting the amount of time it can be used before needing to be recharged. **

To control everything with one remote control, you can invest in a universal remote control that is compatible with all your devices. Make sure to program the remote control with the correct codes for each device, so it can communicate effectively with them. Additionally, you may need to set up different modes or activities on the remote control to easily switch between controlling different devices. Regularly updating and maintaining the remote control's programming will ensure smooth operation of all your devices with just one remote control. **

Yes, a universal remote control can be adapted to a device without an original remote control as long as the device is compatible with the universal remote control. Universal remote controls are designed to work with a wide range of devices and can often be programmed to work with devices that do not have their own remote controls. Users can typically input a specific code or use a learning function to teach the universal remote control the commands for the device. **

No, a universal remote control typically requires the original remote control in order to program it to work with a specific device. Without the original remote control, it may be difficult or impossible to adapt a universal remote control to a device. **
