### Parachute

Described at first as the "Guardian Angel". On 19th August 1913 Pegoud was the first person to descend on a parachute in Europe.

### Parasitic Drag

Resistance to a forward aeroplane movement caused by any non-lifting components of the aeroplane. The fixed undercarriage on most aircraft is one of the main causes of unwanted drag. Rectractable undercarriage will reduce area of drag to virtually zero.

### Parasol

An aeroplane in which the wing is mounted above the fuselage on struts.

### Peak Detect Charger

A battery charger which uses the measured voltage of the battery pack to shut off charging rather than a timer.

### Pilots

A pilot adds a lot of character to any model.

This particular pilot is from Perfect Pilots (perfect-pilots.com).

### Pilot Painting

A detailed guide to modifying and painting a pilot.

### Pitch

The pitch of the aircraft whilst flying is controlled by the elevator. However, if the line of thrust of the power unit and/or angle of attack of the main wing are set incorrectly the pitch may also be a function of engine thrust.

Pitch is the theoretical distance travelled along the axis of rotation of a propeller during one revolution.

### Pitch Control

Provided by the elevators fitted to the tailplane.

### Pitch-Diameter Ratio

The relation between the propeller pitch and diameter, expressed as a mathematical proportion, as 1.5 to 1, and so on.

### Pitch Stability

Stability of an aeroplane in climb and dive.

See: Flaps.

### Planform

The outline of wing or tailplane when viewed from above.

### Planking

Sheet-wood covering accomplished by glueing thin flat wood strips side by side on a fuselage.

### Plastic Model Manufacturers

Useful links and contacts for plastic model manufacturers. more......

### Plywood

Sheet wood made by glueing together two or more very thin layers of wood with the grain of adjacent layers at right angles.

### Pod

A short streamlined fuselage fitted with a boom to support the tail surfaces.

### Pod-and-Boom

A model that derives its name from the appearance of its short fuselage and tail-support boom.

### Polyhedral

A form of dihedral in which there are one or more changes of dihedral in each wing panel.

### Profile Drag

This is the sum of the form and skin friction drag calculated at zero incidence.

### Propeller

An assembly of radially disposed blades with an airfoil shape that when rotated in air produce thrust. more......

### Propeller Manufacture

A simple way to build up a laminated propeller.

### Propeller Sizes

For a given engine size a range of propellers may be fitted. The tables here may give you a starting point and some alternatives.

### Prop Pitch

Props are designated by these two numbers, for instance 10 - 6 (often pronounced 10 by 6). The first number is the prop's length, 10". The second number is the pitch or angle of the blades. The 6 represents the distance the propeller will move forward in one revolution, in this case 6".

### Pusher

A plane in which the engine is mounted ahead of the propeller, so that the propeller pushes instead of pulls.

### PVA

A water based type of adhesive.
