[SPAM] Re: dual elevator servos

[Dave Harmon]

Jerry..I used to have the old PCM 10 and had this same problem.
Here is how I got around it.
 
Create 2 mixes from the elevator to separate aux channels.
Plug both elevator servos into the aux channels.
Don't plug a servo into the elevator channel.

I'll be using either a JR PCM 10 (old) or a JR 8103. When the stick is
moved quickly on the 10, one servo lags. I havn't tried the 8103 and am
not sure if it will work with dual elevator servos.

Your best bet is using separate channels with a mix.  With a Y setup,
you will deprive yourself of the fine tuning capability you will need to
make the travels correct, unless you get lucky with a perfectly matched
set of servos out of the box.  A Matchbox will work fine, but you're
adding weight, cost and an extra point of failure, however unlikely it
is that one will fail.  If you use a mix, not only can you duplicate the
Matchbox capability, you can exceed it if you have a multi-point mix
capability on your radio.  A Matchbox is good for center and end points
and that's it.

I want to use dual elevator servos. Will a Y harness with a matchbox
work or do I have to use two channels? The servos have to be about 1.2"
in length. What is the best JR or Hitech servo to use?
 
TIA
