Similarly, what do the numbers on RC props mean?
All rc propellers are designated two measurements, both usually given in inches. The first number is the diameter of the imaginary disc ('arc') created by the spinning prop i.e. the length of prop from tip to tip. The second number is the pitch and this is the harder of the two to understand - but we'll give it a go
One may also ask, how do you read a RC propeller number? The first number is the prop's diameter. The second number refers to the prop's pitch or how much of a "bite" it takes as it revolves. The number indicates the theoretical distance the prop will advance with each revolution, assuming ideal conditions.
Besides, how do you size a prop?
The size of a propeller is defined with two sets of numbers, diameter and pitch, with pitch always following the diameter.
- Diameter. The diameter is two times the distance from the center of the hub to the tip of the blade.

What is the difference between a 17 and 19 pitch prop?
The 17" prop will give you a better hole shot but lower top speed. If it is to small it the engine may go over the recomended top RPMs. The 19" prop will give you less of a hole shot but a higher top speed if the motor is strong enough to turn it in the recomended top RPM range.
