Product Description

This is an RC Servo Y-Lead for MultiWiicopter or MultiEngine syncronisation of the ESC learning curves - a splitter 8 way Servo connection - 1 male JR - 8 females Futaba which enables you to Y lead off Rx channels for multiple connectors such as THRO -> 8 Multicopter ESC - Hexii Ysiix or Octa - or 8 servo leads.  Compatible with JR servo leads and Futaba RC connectors. the advantage of the short style splitter is to reduce wiring weight and clutter.

 

ESC Learning Curve - Synchronizing the ESCs so they all have the same learnt Min & Max 1095-1905 uSecs
ESCs can learn the range of the Throttle output (exactly) - this is called the learning curve calibration or learning curve setting (nothing to do with programming an ESC)
Because multicopters need PERFECT sycronisation of all the LEARNT values for multiple engines - you need BYPASS the PARIS board Throttle outputs (after doing the Tx Calibration - see wiki this site) I also get my engines calibrated perfectly in 1 step ->  using this combo-calibration-Wii lead on this page - above
 
So I now can program all Eight/Six/four/Three engines in a single step - hooked direct to the Tx/Rx THRO port -
follow your owners manual ESC calibration procedure : -
Preparation
  1. All Props OFF -!
  2. One motor connect to one ESC (so you can hear the beeps) - no prop
  3. All ESC DC inputs connected  using the Voltair® power distribution lead or the CarbonBird power distribution cable - OFF - not powered yet
  4. The male Y-Lead connected directly to the Rx THRO Ch (ch 1 on JR/Spektrum and Ch 3 on Futaba)
  5. All females of Y-Lead connected to ESC - red wire must be active - connected - at this stage
  6. Set throttle side trim on Tx to centre !  check Tx LCD
  7. Make sure you have Mode 2 set in your Tx set-up menu (or Mode 1 if in EU ) and you know which stick on the Tx is actually the throttle.
Learning Curve
  1. Full Throttle -> on the Tx   (make sure your throttle Ch in the Tx is not reversed - Futaba is typical of this) 
  2. PWR to all ESCs on -> (Connect the Power distribution XT60 Yellow connector to 3S or 4S LiPo)
  3. 2 Beeps -> heard (Full throttle position is recorded in ESC CPU - 1905 uSecs)
  4. Throttle to idle ->  
  5. 3 Beeps - Done!  (zero throttle position is recorded in ESC CPU - 1095 uSecs)
 
 
This is only used to calibrate all engines so the props turn at exactly the same time - it is not used for flying!
 
NOTE : After completing the ESC learning Curve process - you can disconnect all the red ESC (centre) wires - leaving only the Black and White wires connected to PARIS engine outputs.  I apply heatshrink to these and never cut them off - this way they can be connected later for re-programming or re-learning the throttle range for the ESc if not syncronized.
