Getting Your Remote Control Helicopter Ready To Fly

posted on 17 May 2013 13:10 by burnell1216
For newcomers to the hobby of flying a remote control helicopter the amount of information to absorb can seem daunting. There is plenty of help online particularly in forums. Getting a helicopter that best fits your requirements is the first step in the process. After that it is all about setting up your helicopter correctly and getting lots of practice. In this article we will focus on the set up phase.

Assuming that you are a beginner and new to the hobby of flying remote control helicopters, chances are you purchased an electric model that was advertised as "Ready to Fly" or RTF. Any of the main brands such as e-flite and align produce quality helicopters and they will be RTF once the battery is charged, however you may need to make some small adjustments.

If you have purchased a "Plug N Play" model the chances are you will already have experience flying remote control helicopters. That does not mean that the setup time for a new helicopter will be any less. In fact with a PNP helicopter you may need more time before taking to the air. As well as programming the TX, you will also have to fit the RX and motor radio controlled helicopter battery pack.

The main point that needs to be stressed about the set up process is that it takes time. Do not, under any circumstances, try to rush the process. Take time to get to know how your new helicopter works. Remember you bought the helicopter as a hobby. It is meant to be enjoyed, not just flown once, crashed and disposed of.

First off, don't assume that the helicopter has arrived in one piece. It does not happen often, but there is always a chance that the model was damaged in transit. Even if you purchase the helicopter from a shop you should always check that all the parts are included and not damaged in anyway.

The next task on your list should be to check the batteries and how they are to be charged. Most RC helicopters come supplied with Li-Po batteries. These are usually charged using a specialist charger that comes with the helicopter so do not rush ahead and try to charge the batteries with a charger you have lying around the house.

When flying remote control helicopters, safety should be your top priority. The same applies when you are setting up your helicopter, particularly when fitting a charged battery. Be sure that the ESC and main rotors are not "armed", otherwise the blades may touch screen tabletstart to spin with your fingers in the way. Do not underestimate the damage spinning rotors can do.

You are probably aware at this stage that the pitch of the blades is changed through movements in the swashplate. As part of the set up process you should check that the swashplate moves as expected when inputs are made to the control system. For example, when you apply left cyclic the swashplate moves to the left.

When checking the control system you should also pay particular attention to the tail rotor gyro. To do this you just have to spin the helicopter around it's vertical axis by holding it between your thumb and fore finger. As you rotate the helicopter you should not the angle of the tail rotor blades changing.

Fixing, upgrading and modifying your helicopter is all part of the enjoyment to be had from owning a remote control helicopter. Taking your time to work through the set up process not only ensures that your helicopter will work properly but will also ensure that you "get under the bonnet" and into the detail of how your helicopter works.

RC Helicopter Gyroscopes

Yaw is a rotation to the left or right in a helicopter. Gyros detect yaw, then send a signal to the tail rotor in order to correct it. So if a gust of wind causes a helicopter to spin right, the gyroscope will correct this and dampen the amount of movement. This is very important, as it means trim adjustment basically only needs to be locked in, and then can usually stay in the same position. 

There are two kinds of gyros when it comes to rc airplanes: heading hold and yaw rate. Early mechanical gyros were yaw rate gyros. This meant that they didn't completely correct, so if a gust of wind hit the tail it would still move it, but just much slower and in a way that makes it easier to control. 
Heading hold gyros are what now come on most standard coaxial gyro helicopters. Heading hold gyros will actually hold the helicopter in the correct position. If a gust of wind hits the tail, the helicopter should ideally stay in the same position. This makes flying so much more straightforward, because the helicopter actually does what the pilot tells it to. 
Heading hold gyros work by detecting the change in yaw then calculating the exact number of degrees the yaw has changed. It then sends a command to the tail rotor servo for that exact number of degrees and corrects. The tail does not move at all and the only changes in yaw are ones issued by the pilot. 
When flying an , the rotors are constantly losing power because the battery is dying. Without a gyro this means that trim needs to be constantly adjusted. With a gyro this is not a problem at all and trim usually only has to be adjusted once before flying. 
Kudos to all those who flew remote control helicopter before the advent of gyros, it must have been tough. Thankfully today gyros are available standard on many hobby grade helicopters, and separately for those building helicopters. Beginners can now learn proper flying techniques in a much less harrowing situation. 
One example of an excellent coaxial gyro helicopter is the Phantom S107. The Phantom is a micro helicopter, small enough to fit in the palm of your hand. It also comes with a USB charger and can be charged from any computer or laptop. The Phantom S107 handles incredibly well, with almost robotic precision. It also does not suffer from "ground effect", an effect that causes larger helicopters to lose control when hovering barely off the ground. The Phantom S107 makes an ideal first helicopter, is outrageously affordable, and is a riot to keep at the office.
