The Explorer and Night Eagle Co-Axial helicopters from Nine Eagles are now available exclusively in the U.S. from Hobby Shops that are part of the BSI dealer network. Both ready-to-fly helicopters come equipped with an advanced rechargeable two cell 7.4V 800mAh lithium-polymer (Li-Po) battery that gives over 12 minutes of flying time. The Nine Eagles 4-Channel transmitter (TX) and gyro equipped receiver (RX) give both helicopters the stability that is ideal for a beginning helicopter pilot but their advanced 180 motors and patented rotor blade design give the Explorer and Night Eagle responsiveness and maneuverability that is unmatched in their class and appreciated by more experienced pilots.

Nine Eagles helicopters are designed for indoor flying but can be flown outdoors when there is little or no wind. Initial flights should be done in as large as possible indoor area (like a garage or family room) that has been cleared of most obstacles. After reading the Nine Eagles User Handbook, initial flights should concentrate on adjusting the trim levers on the TX so that a stable hover can be achieved at about a three foot altitude. The throttle trim lever can be used to finely adjust and maintain a constant altitude. The turbulence caused by the rotor blades when the helicopter is in the ground effect less than a foot off the floor does not allow the hands-off stability that is possible at higher levels.

To prepare for flight after fully charging the Li-Po battery, the TX antenna should be extended to its full length and then the TX switch should be turned on with the throttle (left) stick pulled fully back to the off position. Then the Li-Po battery can be connected to the red plug in the helicopter. After flying, the first step is to disconnect the battery and then turn off the TX. The TX antenna should then be slowly and carefully collapsed. These procedures need to be followed every time you fly your helicopter to prevent the rotor blades from turning unexpectedly.
    

One of the secrets for successfully flying a helicopter is to always move the control sticks slowly and smoothly. Using both your thumb and index fingers on both sticks can help you achieve this. Overcontrol of the throttle is probably the biggest cause of crashes, so adjusting the rotor speed just a notch at a time usually works best.

The amount of wind outdoors can be deceiving. While it may feel there is not much wind five feet off the ground, the speed of the wind usually increases significantly as you get higher. The Nine Eagles helicopters produce a lot of lift at higher throttle setting and you can easily find yourself at and altitude of 50 feet or more in just a few seconds. More likely than not, you may then find the velocity of the wind to be too great for the helicopter to overcome. The throttle should then be pulled back immediately to get the helicopter back to less then five feet off the ground, where you then should work to get it back closer to you. If you have the right stick in a full forward position and the wind still does not allow any forward motion, rotate the nose of the helicopter (using the left stick) 45 degrees to the right of your desired direction of motion. While still holding full forward on the right stick, also apply full left roll to the right stick. This way you almost double the amount of thrust that is applied in the direction you want to go.

If the rotor blades are about to hit an object or hit the ground (crash), your first response should always be to pull the throttle all the way back to off. The helicopter falling from a couple of feet without the rotors turning will usually produce little or no damage. If the rotor blades hit anything, immediately pull the throttle to off and keep it there.

When replacing the rotor blades, do not over-tighten the retaining screws. The blades need to be free to rotate in the blade holder. The top and bottom blades are different so do no interchange them. All replacement parts are available from your local BSI-Nine Eagles dealer.
