small rc helicopter gyro image
Q. There is an RC helicopter that has gyroscope technology and what does the gyroscope technology do? Does it make it hover better or fly faster? Anyone explain Thanks
Answer
Well one easy form of Gyroscope is a fast spinning mass that points at a fixed point in space. It is this feature that is exploited in all manor of devices and vehicles to allow a sense of feedback (electrical or mechanical) to allow the operator/device to know the relative angle between the device body and the gyro direction.
For instance, if a helicoptor is pointing due north and the gyro has spun up and is now stabalised and pointing at a fixed point in space, when the helicopter turns by a few degrees, the angle between the moving helicoptor and unmoved gyro can be measured. this electrical amount is then fed back to the yaw controller which instigates an equal and opposite movement to maintain the direction of the vehicle.
It can be used in all 3 axis of an airborne vehicle to maintain a steady attitude and heading.
The type of gyro used on your model will most likely be a piezo ring mounted on a fixed post. as the vehicle moves, the piezo material wants to stay still and a small force is applied to the material by the moving post. This force is converted into an electrical signal by the piezo properties of the ring material and is then fed back into the directional control system as described earlier. The whole ring, post and electronics of this device are very small and will probably be about 1" cubed.
The last type of gyro is the ring laser type. These are very expensive ($500,000). They rely on a laser emitting a beam that travels around a central point by means of deflecting mirrors. the time that is taken for the beam to travel the full circuit is measured and compared against a known stationary time. If the time is quicker, the aircraft is spinning against the rotation of the laser beam. If the time is slower, the aircraft is spinning with the direction of the beam.
Although, the model helicoptor manufacturers could be bending the truth slightly and claiming that it has gyroscopic technology, which could be as simple as describing the spinning rotors that act as a gyroscope!!!
Hope this helps

what is a good indoor RC helicopter?
Danny
Im looking for an indoor rc helicopter over the price of 60 euro and can be shipped to ireland, I would also like it to have the following,
1. 4ch,
2. Built in Gyro,
3. Made out of metal,
4. Durable so it wont break easily,
5. Decent battery life.
Thanks,
-Danny
Answer
Your criteria will be hard to find to those EXACT specifications. For a durable helicopter doesn't have to be made out of metal. I have plastic RC helicopters on which I fly inside and they have lasted a very long time.
One popular brand of helicopters is SYMA. They make good helicopters. I haven't had any personal experience with their products but I have heard and read very good reviews and feedback on them and have not yet come across any negative feedback.
I just bought a helicopter which is controlled from your iPhone/iPod Touch/iPad - or Android device.
It was just over $30AU, it's got a charge time of about 45min, which is charged from the USB port on your computer. And it flies for about 5-10minutes.
It also fires out little plastic missiles from the sides on command. It's got a range of about 15m.
It's around 7inches long and is 3ch.
The controlling is accomplished by a small infrared transmitter which plugs into the 3.5mm headphone jack in your Apple or Android device.
The name of this helicopter is a U809 Cobra, made by iHelicopter.
