A7: Max speed: 210,000 rpm for 2-pole, 70,000 rpm for 6-pole, 35,000 rpm for 12-pole.

E3. Over-heat Protection: When the temperature of the ESC MOSFETS exceeds 100 Celsius degree, power will be lowered gradually and will resume
when the temperature decreases.

G. Programming via Transmitter
Step 1: Enter program mode
Switch the transmitter on→Pull the throttle stick to the top position→Switch the ESC on, wait 2 seconds, you will hear two “beep” sounds, which
denotes that Max. throttle has been confirmed→Hold the throttle stick at the top position, and then wait 2 seconds until you hear tune “♪ 1 2 3 ♪ 1 2
3”, that means you have entered the transmitter programming mode.
Step 2: Select program parameters
Hold the throttle stick on top position, there’re 7 parameters can be set by using your transmitter. You would hear 7 different indicating sounds which

sound will brings you to the correspondent parameter setting status. The indicating sounds will repeat in turn as follow.

Move throttle stick to the bottom position and then switch on transmitter→ Connect battery pack to ESC→ The long “beep” sound should be emitted ,

Step 3: Select program values

If the throttle stick is neither at the bottom position nor the top position after powered on, it will constantly make “beep” sounds.

After entering parameter setting status, hold the throttle stick on the bottom position, you will be led to the repeat selection of that parameter setting status.

Step 4: Exit program

For some high KV motors, if it shakes while rotating in high speed, the High timing mode is recommended.
