Understanding Brushless RC Motor Specifications. Brushless motors use a standard numbering scheme to describe their physical size and Kv rating. For example: let's assume we have a 5055-3000Kv Brushless Outrunner Motor. We break the numbers out as follows: [50] [55] - [3000] [50] The first two numbers represent the diameter of the motor's

For the “D” dimension of a three-digit frame number, consider only the first two digits and use the divisor 4. In frame number 145, for example, the first two digits divided by the constant 4 is
