After you have mastered the skills of flying an RC airplane, and you still feel the need for an even greater adrenalin rush, you may want to consider the RC helicopter next. If you do, then here are some very important pointers to keep you from becoming discouraged with the complexity of helicopter flight, and some recommendations that will keep the hobby from blowing a hole in your wallet.
Before you get started and even before you purchase your first RC helicopter, you will find that it is very important to learn everything you possibly can about how the helicopter works. What mechanisms surrounding the main rotor cause it to go forward, backward, left and right. What makes the helicopter body spin clockwise or counterclockwise? What happens when the main rotor blade pitch changes? Then, once you understand these characteristics, you will have removed a few crashes from your future.
Papercraft
Keep in mind that once you commit to RC helicopter flying, you will not settle with just one craft, so you may as well start simple with a 4-channel model having counter rotating main blades and an artificial, nonworking or nonexisting tail rotor. Even then, you will save yourself numerous crashes by learning on an RC flight simulator that connects an RC radio-type device to your computer. (The most common brands are Airfly Pro Deluxe, RealFlight, and ClearView). With a simple craft or a simulator, you will be able to train yourself to stay oriented. Staying "oriented" with the helicopter is one of the most challenging aspects of learning this type of flying vehicle.
One thing is for sure, when you start flying the real thing, you are going to crash, so don't blame the manufacturer for your crash. Helicopters are mostly beyond the flying skills of 96% of people in this hobby, so accepting the facts of your future may save you some anger and heartache. Some folks crash a few times and give up, but it takes a lot of practice. Did I say "a lot of practice"? Well here it is again if I did, it takes a lot of practice!
Like I said, learn on a simple helicopter. Don't even think about adding accessories and upgrades to your helicopter unless you are advancing in your skills and are able to fly for a reasonable amount of time and number of times without crashing. The accessories and upgrades WILL NOT cause the novice to fly better because its takes skill and practice. Generally, an RC helicopter is fairly easy to fly as long as you can see it and stay oriented. Plus, you have to understand how the control sticks on the radio affect the movement of the helicopter.
Get an instructor. Beginners can't tell if a certain problem is with you or the helicopter like an instructor can. It is highly likely that there is an RC flying club nearby, and experienced helicopter flyers are very happy to lend you a hand. So, do some asking around before you go off alone to tackle RC helicopter flying.
When it comes to actually flying, don't try to trim Electric Tail Rotor Motor(ETRM) helicopters to make it stop spinning on the ground. They have to be trimmed at eye level(in the air). This is another good reason to have an instructor. Also, you will need to have training gear installed on your skids. This gear is the sticks in the shape of an "X", most of the time with brightly painted foam or plastic balls on the tips. This training gear is like training wheels on a bicycle, to keep your helicopter from tipping over so easily when close to the ground.
When learning to hover, keep the nose pointed away from you, and practice at eye level. Never watch the tail rotor, watch the nose. Staying oriented relies on you concentrating on the position of the nose, because moving the rudder stick to the right causes the helicopter nose to go right (clockwise).
Never fly away until you learn how to hover. Get the art of hovering perfected before you attempt lateral or forward movement. Compared to an airplane, the helicopter ailerons, rudder, and elevator movement are basically the same during normal forward flight, however, the helicopter behaves different than an airplane in that you additionally experience "slide". When making turns with a helicopter, you must keep the nose down, otherwise it will slide out of the turn, disorient you and crash. The transmitter is your helicopter cockpit, so you can re-orient yourself by pointing the transmitter antenna in the same direction as the helicopter nose. However, never fly behind you; always keep the helicopter in front of you unless you are getting yourself re-oriented.
Always use both the index finger and the thumb on the left stick of the radio. On the right-hand control stick, just a thumb is ok if you are comfortable with it. Slight movements of the control sticks cause drastic movements with the helicopter and keeping two fingers on the left stick will help you avoid quick stick movements.
Don't let people watch you when you are learning to fly the helicopter. You need to have full concentration on the helicopter at all times without folks trying to talk you into doing a maneuver that you are not comfortable with.
Never drop the throttle stick or let it spring back for the landing (or any other time for that matter) because the rotors will spring down and hit the tail boom and break it. Always land gently. Never use quick movements on the controls, every move needs to be slow and stable.
Always remember your last move on the controls, because you will get lost at some point and need to reverse your last move until you see your helicopter again or become oriented again. Always keep the helicopter within a comfortable viewing distance, not too far to see, and not so close that you risk hitting something.
Finally, when you crash (and you will), throttle off immediately to save the motor and the rotor shaft. Other broken parts cost less to replace than the motor and the rotor shaft.
