Remote control helicopters have been attracting a huge load of enthusiast’s everyday because of its advent popularity. Some people, upon getting their hands into this very enjoyable new hobby, become puzzled because they come labeled in either ‘fixed pitch’ or ‘collective pitch’; for this reason, many new pilots are in wonderment about the exact difference between the two pitches.
In order to better understand just how these two pitch setups differ, we first have to know and understand what a ‘pitch’ is. In simple terms, the ‘pitch’ is considered to be the angle in which the main rotor blades are positioned. In general, the ‘pitch’ angle measurement is done relative to the horizontal plane. This is because the helicopter is able to generate its lift by rotating its rotor blades through the air. By using the fixed pitch remote control helicopters, when the rotor is able to spin faster, the helicopter will be able to generate more lift making it easier for the helicopter to ascend. On the other hand, slower rotation of the rotor blades will cause generation of lesser lift power and cause the helicopter to have a little difficulty in ascending, or in case it is already in the air, it will cause the helicopter to descend.
On the other hand, collective pitch remote control helicopters employ not only the pitch of the rotor, but also the pitch of the blades. In this setup, the lift generated can be altered by the angle in which the main rotor blade is positioned in relation to the horizontal. To put it simply, while the rotor is rotating at a constant speed, simply changing the pitch of the blades alone can alter the lift that will be generated.
Knowing the technical differences between these two pitch setups will help you in determining which type of remote control helicopters will be able to suit your needs better. Quite simply, a collective pitch helicopter is more responsive, smoother to fly, and a bit more agile. However, they are generally harder to master and this type of helicopter requires more complicated transmitter and costs a bit more than the fixed pitch helicopters. It is important to note too, that collective pitch helicopters have more moving parts, which means that on the event of a crash, they will have more parts that are likely to break more easily than the fixed pitch helicopters, and they also require more maintenance.
In choosing what king of helicopter you would like to use, it all comes down to what type of remote control helicopters that you think you will be most comfortable in using and how serious you are in getting into the RC aviation hobby. A fixed pitch helicopter has fewer moving parts, which means that if you were a beginner in the RC flying business, it would be the ideal type of helicopter to start the hobby with. A fixed pitch helicopter is also much more manageable and easier to fly than the collective pitch variety.
