When you start your beginner RC helicopter training, there are a number of things you need to keep in mind. Radio controlled helicopters for beginners are generally easier to master than the more advanced models, but quite a few things can go wrong when you do your first indoor training flights.
A mostly indoor RC helicopter such as the Nine Eagles Swordfish is a very stable coaxial machine, and a good introduction to the hobby, but you still need to look out for the following potential problems:
1. The Wall Effect
Indoor helicopter flying has its hazards, and one of the first you will experience in a confined space such as your living room is air turbulence. Even relatively small RC helicopters can create a lot of turbulence from the dual main rotors. Air is pushed down, and then out to the sides, and from there on towards the nearest wall or furniture, from where it will bounce back again in various directions.
If you take off cautiously into a low level tail-in hover, by the time you have just stabilized the aircraft and feeling good about your achievement, the first "side-wash" will probably hit the heli and try to force it to the side. The biggest effect will be felt in the tail which will start turning away from the air pressure, and if you don't correct it in time, you can easily become disorientated when you finally start reacting, as the heli could now be facing you from the side.
Luckily the excellent yaw (sideways movement) dampening gyros even in most radio controlled helicopters for beginners should counter and retard this rotation of the tail so that you will soon learn to correct it in time.
2. The Space Race
This problem may seem self-evident, but it is worth mentioning how it can affect your first indoor training sessions. The fact that I was learning within a very small family room to take off, hover and get comfortable with the cyclic controls for basic forwards, backwards and sideways movement, made me cautious right from the start, as I knew there was very "little room" for error!
It so happens that I had no real crashes during that time, just a few more or less uncontrolled landings, and the rotors brushed various pieces of furniture in the process, but always after I had already cut power.
Soon I was filling the whole cubic area of that room, refining my control of my Nine Eagles Swordfish, all the while careful and wary of sudden side, down or up-washes of turbulent air trying to destroy my safety record!
Then, very cautiously, I started practising side-on hovers. The confined space was now becoming even more of a challenge, as I soon found these hovers, and the disorientation one tries to overcome, were stacking the odds against me. However I pushed on and eventually got comfortable enough to very, very carefully try out some nose-in hovers (the controls by now the opposite from where I started, and often, dangerously, giving "pause to though").
After a few such hovers, just as I felt I was beginning to get instinctive control over the heli, I made one of those "little" over-corrections, now in a nose-in hover, and this time I wasn't so lucky. No major crash resulted, but the rotor clipped a chair on the far side of the room when I slipped the craft too far back, and I had to settle for my first repair (replacing the affected blade with the spare that came in the box).
At that point I decided to find a sports hall, or wait for calm days to continue practising - no more indoors at home for me. The bottom line: for simple basic training, where disorientation isn't yet such a big problem (tail-in maneuvers) a confined space is acceptable, but for further training it just isn't worth the risk.
3. Safe as Houses?
Lastly on a point of safety: If you do your basic training indoors at home, often with other family members or visitors nearby, keep in mind that these spinning rotors are actually quite dangerous. The blade tips move at great speeds, and at the same time you are still learning to control where that lethal blade goes! Little kids may get over-excited by your amazing flying feats and inadvertently run across the path of your indoor RC helicopter!
Remote control helicopters are available in a variety of formats to meet the micro-electro-toy-models, on the palm of large specimens of the real thing, which are usually operated gaseous or liquid fuels and can cost several thousand dollars.
Most beginners will start on an electric or battery-powered helicopters RC. These are quiet, small and easy to start - just turn and walk away. (Other types of engines are primed and can be very fickle) Electricalare the safest way to start, and also the easiest to fly.
Electrically powered remote control helicopter has a rechargeable battery to power the motor. LiPo batteries are based on modern mobile technology, and have allowed a new branch of the RC off fly - micro electric helicopter.
All helicopters radio, electric or otherwise a radio transmitter, the pilot (that's you!) Works.
Transmitters have two or more channels, but ifYou want to do something different than flying in a straight line, you need at least three. Each of these canals tells the recipient to send a signal to another component to abandon the craft.
Obviously, the more channels a helicopter, the more it can do. On a simple 3-channel RC channel controls the throttle motor power for example), while the other two work "Servants" - mechanical components to change the stability of the helicopter so it can move to change direction.
There are 2 servantsconnected to a swash plate under the main rotor. All are called cyclic control rc helicopter has a swash plate, and this in turn controls the movement of the bar of flight (the funny thing to attack at right angles to the rotor blade) These servants "Cyclics" and both the work of a control. It allows forward and backward movement of the helicopter (cyclic) and enables the other from side to side (roll cyclic) Another servant acts as a rudder at the stern so that the new helicopterand remain in the air.
When a rotor turns, the body wants to turn the helicopter in the opposite direction - this is called torque. To avoid this, remote control helicopter has two rotors in opposite directions. In a simple three-channel craft are at the center, one above the other. This is a kind of coaxial helicopter. There is no tail rotor, although there is always an oar in any form.
If there is one central rotor, one must havevertically mounted on the tail to balance. This is called the tail rotor (obviously), but also as a rudder. So, as always non-coaxial helicopter "rotor only." This means that there is only along the central axis of the rotor.
