[NSRCA-discussion] Servo wire and battery questions

[Bob Richards]

Jay,
   
  I want to try the CC BEC. I have used a different BEC in a small electric I am flying, from Dual Sky, that can be set to either 5v or 6v output. It does not have as much current output as the CC, however.

                I noticed the other day that Castle Creations has come out with a BEC which can be programmed for different voltages depending on your servo/receiver requirements. Has anyone tried these yet?

    Hi all,

    Return-to-pattern after a long time questions...

     

    Question #1

    I used to use JR servo amplifiers on servos to eliminate noise and ensure strong signal over a long servo lead, especially to the back of the plane. Few of these, if any, are available commercially now, so I assume that there is little need for them any more? (Was never convinced they served a purpose to begin with, but I had never built a plane without them, and never had a problem)

    I will be using JR 955 RX and digital servos. 

    Maybe as simple an answer as "never an issue, regardless of servo wire length".

    Maybe I should twist my wires?

     

    Question #2

    I used to use nothing other than large SR nicads for the flight pack, usually 1100mAh.

    I notice that folks are now using Thunder Power Li-Po batteries, some as small as 480mAh, and several around 800mAh.  Doesn't seem to be much capacity to run six digitals.

    I assume there is a Jaccio regulator to cut it down to 5V or so. Are Li-Pos reliable enough that only one cell is used, or are some folks using a SmartFly dual battery regulator that ignores one battery if it should fail?

     

    I appreciate any calibration on what the "standard" setup might be. 

     

    Thanks,

     

    John
