This is a professional tool that all serious racers should have. It's inexpensive, easy to use, and provides useful data to gain the edge over your competition.

INTRODUCTION - The motor checker is a precision electronic device that is especially designed for measuring the KV value, RPM, current (amp) draw and sensor function of brushless motors, without the need of a speed control. The 2X 16 character LCD display shows real-time measurements of both sensored and sensor-less brushless motors. It runs on any 7.4v Li-Po battery pack, so no additional power suppy is required.

TEST MODES

1. BRUSHLESS MOTOR CHECKING (Both Sensored & Sensor-less)

* KV Measurement (how many thousands of RPM a motor has per volt of input power) For example: A 4.5kv motor produces 4,500 RPM's for every 1 volt of input power. At 7.4 volts this motor would produce 33,300 RPM's (4,500 x 7.4 = 33,300)
* RPM Measurement (8 throttle increments)
* Ampere Measurement (current draw by testing motor up to 18A)

2. SENSOR TEST

* Tests proper function of internal sensors (sensored motors only) - Very important if you are having problems with your motor. This is the first thing to check when your motor isn't working properly.

3. MOTOR/CAR DIFF BREAK-IN

* Fix voltage from 2.5V to 7.2V or 10 steps cycle with variable voltage setting from 2.5V to 7.2V.
