Next to fly, you will need power, the technical term is called the "Thrust". The thrust can either pull the plane foreward with a puller propeller, an EDF (ELECTRICAL DUCTED FAN) ETC.
Now you will need the fuselage, fuselages can vary from different types of aircrafts. Most planes have a 3d scale replica of a real airplane; Some can have a completely scratch buil models sanded off with fan fold insulation foam, but the most exciting type of fuselage is he complete flat profile models, they can perform 3d aerobatics and more.
Step 1: Wings
Some wings are cut out from balsa wood, those are usually the scale models. But some wood can be heavy.
Step 2: The End
Step 3: What to Start With?
Electric planes are much cheaper than fuel burning engines, and fuel engines need more constant care, you will need a lot of patience.
I prefer electric planes more because they barely need any maintenance and they are a lot lighter, which minimises the chance of crashing and breaking up into pieces.
Step 4: Radio Systems
Transmitters and receivers usually come in one single package, the channels can vary from 2 channel for a glider to a 18 channel giant scale plane. The first channel is elevator, then rudder, the third channel is the throttle, and the last is the ailerons. Extra channels are gear up/down, flaps, VPP(variable pitch props), thrust vectorings, parachute dropping or bomb drops.
The transmitter usually include two joy sticks, the joysticks have different setups in different modes, there are 4 modes in total, and mode 2 is the standard mode used in america. The setups are below in the pictures.
The frequency of the transmitter and receiver is the main worry of aircraft flyers. If any two flyers are on the same frequency, it could cause a fatal accident. There are currently three frequency bands, they are
1)27mhz, it is an inexpensive way of starting to fly a plane. But there are only a few frequencies inside the frequency band.
2)35 mhz, it is possibly a good way to fly, but you will need to ask you local hobby shop owner for frequency chips.
3)2.4ghz, I think it is the best radio frequency to use. 80 people can use the 2.4g frequency at the same time without interference.
There are two types of remote,
1-analog remote, it is the most basic and the cheapest type out of all remotes, it basically does not have any computerised controls, you will need a data wire to connect to your computer to program the transmitter.
2-digital remotes, They usually have a led display or a computerised control. They can be programmed straight on the flying field without a computer, that is why i prefer a digital remote.
Step 5: Control Surfaces
Servos are the little mechanical device that pull or push the pushrod which therefore control the movement of the control surfaces.
The servos sizes can vary, from 1.7gram in weight with a torque of 200 grams to a giant digital servo motor weighing up to a few kilograms.
Pushrods are the wires that connect to the servo arm on one end, and connect to the control horn which is on the ailerons, rudder or elevators.
control horns are the tiny things that you either glue or screw in place. You will need to insert the pushrods into the horn and make a z bend. Because z bends are the easiest type of connection from servo to servo horns.
Hinges are the little things that connect the rudder, elevator and ailerons to your wings and stabilizer.They are mostly made of nylon or kevlar strips. There are reinforced special hinge tape for 3d aircraft.
Step 6: Power Source(Electric Powered)
Brushless motors can be saperated into another two groups called the inrunner motors and outrunner motors. Basicly the inrunners have a inner moving axle which drives the propeller, and is suitable for fitting inside a tight space. The outrunners have a external rotating body, which create more power.
Step 7: ESC(Electronic Speed Control)
The ESCs have two wires connect to the battery; a port connecting to the receiver, and wires connect to the motor.
