Flying remote control airplanes is an amazing hobby that is enjoyed by many people around the world. There is nothing quite like the freedom of the open skies, the adrenaline rush of your first take off, and the satisfaction of having a skillset that many people do not have. This is a hobby that requires patience and offers many challenges but it is also very rewarding and enjoyable.
The first step will be to build your airplane. It’s a rather amazing experience to slowly see your plane come together and then sitting back after you have finished your project and admiring your creation. If your new or just starting out with RC planes it’s important to research and gain some knowledge on how aerodynamics relate to RC planes as flying can take a bit more skill than most people realize which has resulted in some rather undesirable but avoidable outcomes.
Beginner’s Guide to RC Helicopters
NOT LONG AGO, RC helicopters were nothing more than a curiosity. There were only a handful of kits on the market and you practically had to be a mechanical engineer to put one together.
There might be one—or if you were lucky, two—helicopter pilots at a local flying field. Helicopter pilots would usually be left to themselves, subject to an array of whispered jokes such as, “Those things don’t fly; they are so ugly the ground repels them,” or “They don’t fly, they beat the air in to submission,” and others. Knowing looks were exchanged by the airplane pilots that said, “He’s a nice enough guy but he’s a little strange; he flies helicopters.”
Fast forward to today. At many flying fields, the helicopters present at a field can equal or even exceed the number of airplanes. Even if they are hidden in the back seat of their trucks, many of the sneering airplane pilots secretly own an electric helicopter or two.
Now there are so many kits available in nearly every imaginable shape and size that a beginner interested in getting started in the hobby can easily be overwhelmed. Offerings range from RTF helis that you can unpack, charge, and fly, to kits that you have to build from bags of parts.
Sizes range from diminutive electric-powered models that you can fly in your living room to turbine-powered scale masterpieces that require a trailer to transport them to the flying field. A first-time helicopter buyer is likely to encounter a confusing array of terms such as ARF, RTF, BNF, coaxial, fixed pitch, collective pitch, electric, nitro, and gas.
What this article is going to attempt to do is explain these terms and help the first-time helicopter buyer make an informed decision concerning which category best suits his or her needs and interests.
Size (abridged from article):Modern electric-powered helicopters are slightly more difficult to classify size wise, but they generally range from rotor spans in the 7-inch range (the tiny T-Rex 100) to the 700 size, spanning nearly 5½ feet. I’ve seen an electric-powered Scale helicopter with a main rotor span of slightly more than 90 inches!
Loose comparisons can be made to nitro-powered helicopters. A 550 electric is roughly the same size as a .30-size fuel-powered helicopter; a 600 electric is .50 size, and a 700 electric is .90 size. The 100 through 450-size smaller electrics have no mainstream fuel-powered equivalent.
Many factors go into deciding which size helicopter to purchase.
Flight Controls (abridged from article): Not unlike an airplane, a helicopter requires four primary flight controls: pitch (elevator), roll (aileron), yaw (rudder or tail rotor), and throttle. The elevator and ailerons are combined on the right stick (Mode 2) in what is called the cyclic control. This is what gives us directional control of the helicopter.
Rotor Head Designs (abridged from article): As mentioned, we generally have two types of main rotor head design: fixed pitch and collective pitch. The advantage of fixed pitch is that the design is simple so it’s inexpensive to produce.
As the name implies, the pitch angle of the main rotor blades is fixed and the amount of lift produced varies by changing rotor head’s rpm. In addition to the simplicity of the design, a fixed-pitch rotor head requires only one channel to control altitude.
The disadvantages of fixed pitch are that performance is somewhat limited, and if you get the rotor head too slow while descending, you might not get the rpm back in time to prevent impact with Mother Earth.
Tail control (abridged from article): Torque produced by the main rotor has to be counteracted or the heli’s fuselage will spin in the opposite direction of the main rotor. Typically this is accomplished by the addition of a tail rotor.
Like the main rotor system, the tail rotor can be either a fixed-pitch variable-speed design, or a fixed-speed variable-pitch design. Fixed-pitch tail rotor designs have a small motor mounted on the tail and the variable pitch ones drive the tail rotor from the main motor.
Fuel or electric power (abridged from article): The debate between fuel power and electric power has been going like the Energizer Bunny. The winner is … there’s no clear winner. Each has its own learning curves and unique support equipment to purchase.
In the case of fuel power, you need a fuel pump, glow plugs and a way to light them, and, of course, fuel. Then you have to learn to operate and tune an internal-combustion engine. Most fuel-powered helicopters use traditional model fuel (methanol, oil, and nitro methane), but there are two-stroke gasoline-powered engines available as well.
Several flights can be made on a single receiver battery charge so you can get a number of flights in while only stopping to refuel.
If you go with electric power, there are speed controllers, motors, and batteries to purchase. To fully explain how to properly choose your electrical system components such as the speed controller, electric motor, and batteries would encompass a small book.
Fortunately there are a number of packages available, supplied with components chosen from extensive flight testing, that are proven to work well together. Then you have to learn how to properly charge, and handle LiPo batteries. Credits: http://modelaviation.com Written by Andrew Griffith http://
RTF rc airplanes will be the very best strategy to get started in radio management flying if you happen to be not whatsoever bothered about building a model airplane, and just desire to fly one.
The abbreviation ‘RTF’ stands for Ready To Fly which suggests that you just, the consumer, will not need to do something to the design to get ready it for flight aside from set up the gear batteries that manage the radio and do some extremely standard last assembly function, like attaching the wing and tailplane for the fuselage. There may be no development involved in putting collectively an RTF plane.
RTF rc airplanes have launched a huge number of people towards the pastime of radio control flying, but it is only in much more recent a long time that they have become so widely available and have been priced reasonably. Immediately before the creation of RTFs these kinds of kitshad been the way in which to go but these deterred potential modelers who just wanted to fly and weren’t also thinking about the building facet of your hobby.
Electronic Speed control (ESC) systems for brushed motors are often very different by design. This explains the fact that brushed ESCs aren’t compatible with brushless motors. Brushless speed control systems are basically for driving tri-phase brushless motors. It does this by sending a series of signals for rotation. The correct phase often varies with rotation of the motor. This rotation is take into account by ESC. The controller generates the signal depending on the back EMF signal it receives from the motor. The EMF signal guides the controller on the position of the rotor and what fets to switch on.
Brushless motors, also known as inrunners or outrunners, have become very common with radio-controlled airplane hobbyists because of their high level of efficiency, longevity, power and light weight compared to traditional brushed motors. Brushless motor controllers are however much more complex than their brushed counterparts.
Various RC vehicles run on different power sources. Among these, RC cars or boats that run on electricity are the easiest to operate. With electric remote control cars or boats, there is no need for sophisticated technical knowledge or the need for glow plugs or fuel.
The only requirements are to charge the batteries and to ensure correct wiring. That’s pretty much it!
Rechargeable battery packs for RC vehicles can be typically either one of the following: NiCd, NiMH, or Li-Po cells. Following are more information on RC batteries.

The radio controlled helicopters which are popularly called RC Helicopters aircraft. There those that are prototypical available for greater maneuverability while these types have a reduction or decrease in the aerobatic control. These are RC helicopters with wifi cameras.
These aircrafts are operated by users using the remote control due to the tiny servos that have been placed on a particular part of the plane. Most people who operate RC helicopters do so for entertainment purposes.
The Electric Radio Controlled Airplanes are admired more and more these days because of their ready-fly models. These airplane models are available in different styles and are designed so that it can be used straight out of the pack, without building the complete plan.
Remote control watercraft can be split into a number of types: electrical, breeze, gasoline, along with nitro. Remote controlled power fishing boats include the least difficult to take care of and they are relatively low-cost when compared to the other selections.
