Terms Used When Describing a TX System
Understanding the control system of your remote control helicopter is key to getting the most out of model. If you have opted for a toy or coaxial model then the system will not be as complicated. You will be able to get the heli in the air fairly quickly, which is what they are designed for anyway.
If you have decided to purchase a CP remote control helicopter then be prepared to spend some time understand how the model works and is put together. Cutting corners at the start will cause you problems within weeks.
We have already explained some of the terms used to describe the TX system and we will continue with some more in this post.
Throttle Hold
This switch can be turned on and off. When it is activated it stops the rotor blades from spooling up if the throttle is acidentally moved forward. It is a very useful safety feature.
Gyro Switch
This switch allows you to pre programme the TX with different gain values. By flicking a switch you can change from one value to another. This functionality is usually used vy experienced flyers who perform 3d manoveurs.
Expo
Some helicopters can be very sensitive especially those capably of 3d flying. This can be very disconcerting for a novice or someone who prefers flying more sedate routines. The expo function allows you to increase / decrease the control sensitivities around the central
stick positions. For small stick movements the control movement can be programme to react slower and for large movements it can be programme for fast reactions.
Multi Model Memory
For those who plan to fly multiple models this is a really useful feature and highlights one of the main advantages of buying a quality TX. Transmitters with this function have multiple slots that store set up values for a range of remote control helicopters. Some will even have a slot for external memory cards.
For those serious about the hobby of flying a remote control helicopter it is well worth investing in a top of the range TX. As your skill level increases you will come to appreciate all the extras such transmitters offer.
