The Syma S107G Metal Series RC Mini Helicopter in the video was a Christmas present that we had a great time with.  It’s a sleek good looking mini UAV that’s well built, being constructed mostly of metal, with plastic rotors. Even with it’s metal frame it only weighs 34g. This counter rotating (coaxial) two rotor helicopter was easy to fly right out of the box. Or should I say as soon as the rechargeable 180mAh Li-poly battery was fully charged by using the included USB charging cable that plugs into the controller or usb port.

In flight it is extremely stabile due to the fact that it’s stabilized with a built in gyroscope. The gyroscopic stabilization system consist of two counter weights mounted on arms above the coaxial rotors which turn in opposite directions. The system made hovering very simple to the point that you simply move the throttle up and down to vary the power and this provides lift or settling of this mini copter. The controller is an easy to use,  six AA battery powered, 3 channel infrared 3 way controller with trim. Since the controller transmits it’s signal via infra red it won’t interfere with your other RC models.

To fly all you have to do is add power to raise the aircraft off the ground then you use the other joystick to move left, right, forward, or back. Then you’re on your way with no real training time. On the nose is an LED light that continuously flashes when the craft is powered. During our time flying the Syma 107 indoors it had lots of impacts with the walls and ceiling but it never broke. I attribute this to the light weight metal frame that Syma used for the construction of the fuselage and tail boom. The S107 is owner repairable and inexpensive crash packs that contain an assortment of spare parts and rotors are available.

The frame does leave the gear box open for viewing but, the exposure of the gears and circuit board leaves some concern about hair or other debris possibly fowling the gears. Fortunately, we never had a problem with that. Charging time was 30 to 35 minutes and flight time averaged 8 minutes. I would definitely suggest this inexpensive model for both beginners and experienced pilots and at an average cost of $20 it’s cheap fun.
