Hey guys,

well i have the Apexi Power FC and i am able to see the "knock-lvl" of the stock sensor. The Sensor is plugged into a hole in Rotorhousing 1.
The knock readings are very high, and i dont know why. I have tried richen the mixture and retarting the timing extremely but the knock wasnt really lower.
Yesterday i tried out and mounted the knock-sensor to the Rotorhousing 2. and the knock-lvl dropped by 1/2!
i heard J/S Knock sensors for the FD are mounted to the rotorhousing 2. so is there any difference between Rotor1 or Rotor2?

thanks-
