First-person view (FPV), also known as remote-person view (RPV), or simply video piloting, is a method used to control a radio-controlled vehicle from the driver or pilot's view point. Most commonly it is used to pilot a radio-controlled aircraft or other type of unmanned aerial vehicle (UAV). The vehicle is either driven or piloted remotely from a first-person perspective via an onboard camera, fed wirelessly to video FPV goggles[1][2] or a video monitor. More sophisticated setups include a pan-and-tilt gimbaled camera controlled by a gyroscope sensor in the pilot's goggles and with dual onboard cameras, enabling a true stereoscopic view.

Radio Waves or Frequency Explained
Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infraredlight. Radio waves have frequencies as high as 300 GHz to as low as 3 kHz, though some definitions describe waves above 1 or 3 GHz as microwaves, or include waves of any lower frequency. At 300 GHz, the corresponding wavelength is 1 mm (0.039 in), and at 3 kHz is 100 km (62 mi). Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are generated by lightning, or by astronomical objects.

Cloverleaf Build
cloverleaf antenna is a circularly polarized wire antenna, with a radiation pattern similar to adipole antenna.The Cloverleaf is a closed-loop antenna, meaning that the signal and ground wires are connected. Measuring between signal and ground with a multimeter would read a short circuit. However it works great as an antenna. The cloverleaf has 3 lobes at 120° apart from each other in the horizontal plane and angled 45° in the vertical plane. It may look funky, but it’s an excellent transmitter antenna. In fact its one of the best FPV video transmitter antennas out there at the moment.

Vee Antenna Build
An inverted vee antenna is a type of antenna similar to a horizontal dipole, but with the two sides bent down towards the ground, typically creating a 120 or 90 degree angle between the dipole legs. It is typically used in areas of limited space as it can significantly reduce the ground foot print of the antenna without significantly impacting performance. Viewed from the side, it looks like the English letter "V" turned upside down, hence the name. Inverted vee antennas are commonly used by amateur radio stations, and aboard sailing vessels requiring better HF performance than available with a short whip antenna. Inverted vee antennas are horizontal polarized and have a similar pattern compared to a traditional horizontal dipole.

What is a Helical Antenna?
helical antenna is an antenna consisting of a conducting wire wound in the form of a helix. In most cases, helical antennas are mounted over a ground plane. The feed line is connected between the bottom of the helix and the ground plane. Helical antennas can operate in one of two principal modes — normal mode or axial mode.
In the normal mode or broadside helix, the dimensions of the helix (the diameter and the pitch) are small compared with the wavelength. The antenna acts similarly to an electrically short dipole or monopole, and the radiation pattern, similar to these antennas is omnidirectional, with maximum radiation at right angles to the helix axis. The radiation is linearly polarised parallel to the helix axis. These are used for compact antennas for portable and mobile two-way radios, and for UHF television broadcasting antennas.
In the axial mode or end-fire helix, the dimensions of the helix are comparable to a wavelength. The antenna functions as a directional antenna radiating a beam off the ends of the helix, along the antenna's axis. It radiates circularly polarised radio waves. These are used for satellite communication.

Flaps Setup
Flaps are a type of high-lift device used to increase the lift of an aircraft wing at a given airspeed. Flapsare usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to lower the minimum speed at which the aircraft can be safely flown, and to increase the angle of descent for landing.

Elevon Mix Setup
Elevon mixing is the mix between ailerons and elevator. Meaning, with only 2 servos, you are able to control the elevator and the aileron with only one surface (the elevons).


Multiwii is an open source project code which runs on Arduino bootloader based boards in order to fly a multirotor platform; was initially developed to support Nintendo Wii console gyroscopes and accelerometers.

PID Setting Explained
PID stands for Proportional, Integral, Derivative. Controllers are designed to eliminate the need for continuous operator attention. Cruise control in a car and a house thermostat are common examples of how controllers are used to automatically adjust some variable to hold the measurement (or process variable) at the set-point. The set-point is where you would like the measurement to be. Error is defined as the difference between set-point and measurement.
(error) = (set-point) - (measurement) The variable being adjusted is called the manipulated variable which usually is equal to the output of the controller. The output of PID controllers will change in response to a change in measurement or set-point. Manufacturers of PID controllers use different names to identify the three modes. These equations show the relationships:
P   Proportional Band = 100/gain
I            Integral = 1/reset          (units of time)
D          Derivative = rate = pre-act   (units of time)
Depending on the manufacturer, integral or reset action is set in either time/repeat or repeat/time. One is just the reciprocal of the other. Note that manufacturers are not consistent and often use reset in units of time/repeat or integral in units of repeats/time. Derivative and rate are the same.
Choosing the proper values for P, I, and D is called "PID Tuning".

RC Scratch Build Plane

Center of gravity (CG) limits are specified longitudinal (forward and aft) and/or lateral (left and right) limits within which the aircraft's center of gravity must be located during flight. The CG limits are indicated in the airplane flight manual. The area between the limits is called the CG range of the aircraft.

Foam Airfoil
An airfoil (in American English) or aerofoil (in British English) is the shape of a wing, blade (of a propeller, rotor, or turbine), or sail (as seen in cross-section). An airfoil-shaped body moved through a fluid produces an aerodynamic force.
