Walkera DragonFly 10 X-Factor Double-Rotor Radio Remote Control RTF Helicopter

The DragonFly is more powerful, flies longer and has better servo resolution for more precision flying indoors and outdoors. The suggested retail price is $399.95 and in under an hour (all battery charge time) you will be airborne in your family room or back yard.  The helicopter is easy to fly and spot landing the DragonFly on the kitchen table or other platform presents an entertaining challenge. You will also be impressed with its stability!

• Main rotor diameter: 18.0”
• Tail rotor diameter: 2.25” (non-functioning)
• Length: 17.25”
• Height: 9.00”
• 2-cell 1250mAh Lithium-Polymer Battery
• Battery charger
• 4-Channel FM 72Mhz Radio included (uses alkaline batteries)

The DragonFly H10 comes with a 4-channel, 72mHz transmitter, 1250mAh lithium-polymer battery pack and charger. The transmitter has two features worthy of note. On the front there is a color battery meter which makes it easy to tell when it is time to replace the alkaline batteries. On the back, there are open dip switches for non-standard heli flyers to alter the configuration of the radio to a style they are accustomed to using. Charging the pack takes about an hour or so using the supplied charger. We recommend you use this charger unless you are experienced and have a LiPo charger on hand. Lipo batteries can be very dangerous if improperly charged.

You will be impressed with the simplicity of this product. Just 4 years ago, nobody could have imagined a helicopter model that is as easy to use as the DragonFly H10.

Twin Contra-Rotating Blades Provide Twice the Stability

The DragonFly H10 has two sets of main rotors and a freewheeling tail rotor that does not affect flight. The contra-rotating main rotors eliminate the need for tail rotor compensation because they move in opposite directions, canceling each other’s rotational torque . In addition, the dual blade setup provides more gyroscopic stability. In plain English: you look much better on the stick than you thought you would.

On close inspection of the main rotor unit, you will notice that the lower rotor provides cyclic control for the ship. To yaw the helicopter (left and right), one of the main rotors either slows down or speeds up to create an imbalance in torque. This results in the DragonFly H10 turning in the direction opposite to the rotation of the faster moving rotor.

Indoors, the cyclic control is plenty responsive. Outside is another story, unless there is absolutely no wind. It has the rate adjustment and gyro adjustment pots right on the side of the ship, allowing you to make the DragonFly H10 more responsive in slightly windy conditions. It also lets more experienced pilots tune the ship to their liking. The DragonFly H10 ships with the rate and gyro pots at the low setting for maximum stability on initial flights. Keep in mind the aim of the DragonFly H10; an entertaining R/C heli that allows beginners to get into the hobby inexpensively and experienced pilots to add a "leisure" ship to their stable at an extremely reasonable price.
