Servo mounting help needed.

[John Pavlick]

Steve,
 Good observation. I'd be interested in an explanation for this too. I agree
with your thoughts on how the servos might react to this type of mounting.
In the "traditional" mounting arrangement it seems the servos are more
stable with the output arm at 90 degrees to the case. With the arrangement
shown for the Epsilon, it seems like they would want to rock more easily. We
might be missing something so maybe someone will shed some light on this.
Remember the old Kraft linear servos? They were inherently better all
around, especially for split elevator setups. Why doesn't someone make
something like that again?

  Subject: Servo mounting help needed.


  I'm beginning construction on a pair of CA Models "Epsilon" kits for next
season. I'm very pleased with the quality of these kits but one thing has me
puzzled. Rather than utilizing the traditional lengthwise servo mounting,
the design calls for mounting them sideways for both tail surfaces &
ailerons. Has anyone had any experience with this type of mounting?  Here's
a look at what I'm talking about:

  It seems to me that this type of mounting could result in movement of the
servo when force is applied. I've spent a boatload of money on digital
servos & top quality hardware for these planes & the last thing I want is
servo movement which defeats any precision setup. At this point I've decided
to modify the design for traditional mounting unless you "pros" can shed
some light on the sideway method. Thanks.
