Micro Radio Control Helicopter

By: Nigel Taylor

This was a Christmas present and sadly it did not work when opened as it just would not charge up, there was something seriously wrong. I took it back when the shops re-opened after the holiday and happily it was exchange for another one straight away, this time success.

The box without the helicopter, removed quickly for flight.

This particular design does look very realistic as you can see in the following images. It is very very small and extremely light. At first it is a bit scary, it is going to break. Well, having flown it into walls, decorations and other objects I can say that it is very robust.

The infra-red control works very well, it can have some glitches but rarely and they are just momentarily.

The main rotor is driven via a very large gear ratio and a small high reving motor.

A single main rotor with balance flybar. The tail rotor provides a very adequate reaction to the main rotor in flight.

The tail rotor is driven by another very small motor. Note fluff around the driveshaft, this needs removing carefully before flying again.

A very open structure to reduce weight, this is an extremely light machine. The result is you do get a reasonable flight time and performance. The rate of change of height and rotor speed is not brilliant and you do need to carefully increase or decrease the throttle to get a smooth flight. If you decrease the power too quickly you will need a lot of height in which to recover the rotor speed to cushion the landing.

As you can see in the video, I found it best to hand launch the helicopter. Perhaps more of a case of releasing the helicopter once there is a neutral balance. Also, the more you angle the nose down when you launch the faster the initial speed and the more space you will need to turn.

All in all, a great model and surprisingly good fun for around 20 to 25.
