The Reflex is one of the many micro remote-controlled helicopters on the market small enough for indoor flight. Manufactured by Air Hogs, the Reflex was engineered for stability and control with precision flying in mind. Because of its design, the Reflex has flight characteristics that require specific techniques for proper operations, though once you've learned a few tips to setting up and controlling the helicopter, you'll soon be flying like a pro.
Control
The Reflex gets its name due to the design of its blades. The helicopter's blades have an increased reflex, which means that they curve up slightly that gives the helicopter increased stability during flight. It's a twin-blade system, using counter-rotating rotor blades for hover and twin drive props for directing flight. This system gives you an easy hovering helicopter with yaw control for height, forward and reverse. The Reflex uses a dual stick transmitter with the left stick as a throttle, controlling the craft's altitude, and the right stick provides directional control.
The Reflex is a fixed-pitch helicopter as opposed to being of the collective-pitch design found in most RC helicopters. Single-pitch helicopters are easier to control and provide a natural hover state from start-up. But in order to gain this stability, you have to trim the rotors properly.
Trim for Hover
To trim the rotors, use the trim wheel located on top of the Reflex's rotors. Check the current trim by pushing the throttle forward until the Reflex lifts from the ground, watching to see if it rotates during the hover. If there is any rotation, note the direction, and then turning off the helicopter. Turn the trim wheel in the opposite direction of the rotation. Use small turns of the trim wheel to avoid over adjustments. Once trimmed properly, the helicopter should hover without any unapplied directional rotation.
Directional Tips
The Reflex's throttle controls the power used for the directional controls. By increasing the throttle, you gain greater control of the helicopter's directional capabilities. At high throttle, you'll have more precise controls of turns and height changes. This throttle control makes it more difficult to operate at low speeds though, complicating spot landings made at low hover heights. To perform low-speed maneuvers, make adjustments for slower reaction times in your controls. Operate the helicopter at low speeds as though flying in slow motion.
The Reflex is a single-directional helicopter. In order to turn, you need to stop all forward or backwards motion and enter a hover. After completing your turn, you can increase your speed for forward flight in the new direction. The same holds true for height adjustment, although you can increase the speed of height changes by increasing the throttle.
