Yes.  Works very well.

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
