## What does 2/3/4/6 channels mean?

2 channel aircraft:

With 2 channels one channel is used for power and the other controls the rudder. Allowing you to steer the aircraft left and right. In some aircraft to minimise the weight they slow one on the engines down causing the aircraft to turn left or right. The way the aircraft climbs and descends is by the engines or elevator on the back of the aircraft pointing up. So as you increase the power on the engines the aircraft climbs.

3 channel aircraft:

With 3 channel aircraft the first channel deals with power control the second controls the elevator allowing you to control the aircraft in pitch, and the third controls the rudder allowing you to steer the aircraft left and right.

4 channel aircraft:

As the 3 channel. But the difference is that you have control of the ailerons on the wing which allows you to control the aircraft in roll. Increasing the aerobatic ability of the aircraft and the control ability.

5 and 6 channel aircraft:

These channels are usually ancillary channels and can be used for things like raising the wheels up and down, moving flaps out on the wing.

2 channel helicopter:

The first channel is used for power enabling the helicopter to climb and descend, the second channel turns the helicopter to the right or the left on the horizontal plane. The way the aircraft moves forwards is by a weight on the helicopters nose tilting the helicopter forward. There is no backward movement.

3 channel helicopter:

The first 2 channels are used as the 2 channel helicopter, the third channel allows you to move the helicopter forwards and backwards.

4 channel helicopter:

The first 3 channels operate the same as the 3 channel helicopter but with the fourth channel you can roll the aircraft around the longitudinal plane. Allowing you greater control over the helicopter.

6 channel helicopters:

The first 4 channels are used in the same way they are in the 4 channel helicopter. The remainding channels can be used to fix the rotor at a set speed for hovering or allowing you to control the helicopter in inverted flight.

## What is the difference between Infra red (I/R), 35mhz and 2.4ghz?

I/R

The technology used is the same technology found in tv remote controls. There are 3 I/R bands A,B and C. This allows you to fly up to 3 aircraft together in the same area as long as you are on different bands. The problems with this technology are interference problems and range problems.

35mhz:

This technology uses radio waves created by moving crystals within the transmitter and receiver. 35mhz comes in different areas of frequency bands. You can fly many aircraft together on this frequency as long as you do not have conflicting bands. The problem with using this frequency is the interference you can receive from bands close to the one you are using, and the large aerial you have to have on your transmitter box.

2.4ghz:

This is the most modern technology available. It allows you to have many different aircraft operating on very close bands together without the risk of interference. You have a small little stubby aerial on the transmitter box, meaning you are less likely to damage it.

What is the difference between a NIcad battery and a Lipo one?

A nicad batterey stands for nical cadilum. The battery is very bulky and heavy and does not produce that much power compared to the size of the battery. It is very safe regarding charging and keeping cool and is quite robust. Also the cost of these batteries are nearly ¼ of the price compared to the lipo.

Lipo:

A lipo battery stands for lithium potassium. The batteries are usually very light and produce a lot of power compared to the Nicads. The problem is with this battery is that you have to be careful with charging it as it can explode if over charged. You have to be careful not to damage the outer wrapping. Also it is far more expensive than the Nicad battery.

## What Aircraft should I buy as a beginner?

Out of our products as a novice pilot who has a large amount of space to hand I would recommend either the 3 or 4 channel Wing dragon. Or the Palm Z or Twin Z range.
