APC 6 x 4 IC Propeller (RB411318)

This is an APC IC propeller it is designed specifically for glow and gas engines.They are heavier than their electric equivalent and have a thicker airfoil.

Specification
* Application: Glow or gas engines only
* Diameter:
* Pitch:

Extra Information
The size of each propeller is identified by two numbers, separated by an "x" and is stamped on the propeller blade. The first number represents the diameter of the propeller in inches. The second number is the pitch in inches per revolution. APC propellers are by default assumed to be of a standard type (Sport), unless modified for a specific characteristic or purpose. Sport propellers are intended for use with internal combustion or IC engines. The letter or letters following and or preceding the propeller size indicates the type and or modification. The letter or letters that precede the propeller size in the part number are identified below. The various propeller types and modifiers are described below.

Class Type:
* E - Thin Electric or Electric (electric only)
* F - Folding Blade (electric only)
* MR - Multi-Rotor (electric only)
* SF - Slow Flyer (electric only)
* R - Reversible ESC (electric only)

Modifier:
* B - Black Color (precedes diameter in part number)
* B4 - Bundle Pack (2CW and 2 CCW propellers)
* D - Durable Material (precedes diameter in part number)
* W - Wide (chord)
* N - Narrow (chord)
* NN - Very Narrow (chord)
* PN - Pattern
* P - Pusher (or reverse rotation for electrics)
* ST - Self Tightening
* C - Carbon Material 40% Carbon / 60% Nylon by weight
* () - Reserved for Special Notes

A combination of the above may be used. For example: MRP is a Multi-Rotor Pusher propeller. If there are no letters behind the propeller size, then it is a standard rotation Sport propeller. Although sport propellers are intended for use with internal combustion engines. Electric propellers are intended for use with electric motors only.
