 ## Wiring:
-* Connect channel 1 of your receiver to blue wire and channel 2 to green wire on right sensor cable(shorter)
+* Connect channel 1(steering) of your receiver to blue wire and channel 2(speed) to green wire. By default, the right sensor cable(shorter) is used to limit the noise
 * PWM is highly prone to noise : keep cables short, use 100nf capacitors, use shielded cable, use ferrites, stabilize voltage
 
 ⚠ Red wire from sensor cable delivers 15v !!!
