Speed Controller Calibration Cable for Quad
$3.00
Description
This is an RC Servo Y-Lead for the ESC learning curves – a splitter 4 way Servo connection – 1 male JR – 4 females Futaba which enables you to Y lead off Rx channels for multiple connectors such as THRO -> 4 Multicopter ESC –  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
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
So I now can program all four  engines in a single step – hooked direct to the Tx/Rx THRO port –
follow your owners manual ESC calibration procedure : –
Preparation
All Props OFFÂ !!
Learning Curve
- Full Throttle -> on the Tx  make sure your throttle  in the Radio is not reversed – Futaba is typical of this
- PWR to all ESCs on
- 2 Beeps -> heard
- Throttle to idle
- 3 Beeps – Done!
This is only used to calibrate all engines so the props turn at exactly the same time – it is not used for flying!
Â
This is a must cable cable for every multirotor tool box!
save time calibrating all your ESC at one time. and get them exactly in sync  .
4-Way Splitter Cable:Â 6″ long. One male to four female. JR/Hitec style plug. Gold plated contacts. 3 conductor. 22 AWG.
