Problems With the Walkera Lama 2 2.4GHz 4CH Electric RC Helicopter

Walkera's Lama 2 RC Helicopter is an indoor remote control aircraft designed for ease of use. The helicopter's small 50 gram body and powerful 3.7V motor provide up to eight minutes of flight time on each battery charge. The helicopter communicates with the controller via 2.4GHz radio signals. The controller is paired to an individual helicopter, allowing up to 20 Lama 2 helicopters to operate in the same area.

Controls
- The Lama 2 is primarily controlled with two control sticks on the control pad. These control sticks control the helicopter's thrust, bearing and tilt. Thrust determines altitude, bearing determines direction and tilt determines forward or backward movement. The controller also features four trim controls that are used to balance the neutral position for the control sticks. If these trim controls are not properly set, the helicopter will not hover properly; it may ascend, descend, turn or move without any input from the user. The controller also features 12 DIP switches inside of a compartment on the bottom of the controller. The first four switches reverse the trim input. The last eight switches have no function. When these switches are in the "on" position, adjustments to the trim controls will have the opposite effect.
Pairing
- Before flight, the helicopter must be paired to its controller. Pairing ensures that a helicopter will only receive commands from a single controller. Failure to pair can result in interference from nearby controllers, potentially causing your helicopter to stop responding. Code pairing occurs automatically when you turn on your controller and your helicopter. You must turn your controller on before connecting the power cable to your helicopter for proper pairing. Pairing should only take about 10 seconds, after which the power indicator on the controller will stop flashing. It is crucial that only one person attempt to pair a controller to a helicopter at a time. If multiple pilots attempt pairing they may pair their controller to another helicopter or pairing may fail altogether.
Adjustments
- The Lama 2 has several adjustable points that you can change to keep the helicopter flying properly. It is considerably more difficult to control the helicopter if you don't adjust it. The battery pack can move forward or backward to adjust the helicopter's center of balance. The helicopter also has an adjustable swashplate and rotor blades. Walkera also offers replacement parts to replace permanently damaged portions of the helicopter. Before adjusting or changing any components, disconnect the power cable on the helicopter.
