<DIV><FONT face=Arial size=2>I'm using servos in my stab on my current Aries
and what you've just pointed out is really the only concern I have about the
setup. Since the servo is buried in the stab the control arm must be at
least a certain length to extend out far enough to attach the push-rod and not
bump into the base of the stab. The result is that this ends up creating too
much throw at the servo arm and thus you're not using 100% of your servo range
in moving the elevator. I've already got the control horn position as far out
as it can go but I still only use about 65% to 70% of my servo
travel.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>That being said, I really haven't noticed it
being to sensitive or not enough granularity in the elevator control and
I have not observed any problems with the elevator halves throwing unevenly. I
have just over 100 flights on the plane. I've had several other pattern pilots
fly my plane (even recently), from Advanced to FAI, and everyone seems to
think it flies very true and straight. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Now, after that glowing endorsement I must tell
you that on the new plane I'm building I plan on using pull-pull on the
elevator. Why? Ease of setup and to see if I notice any
differences.</FONT></DIV>

servo embedded. The servo is the <FONT face="Times New Roman" size=3><FONT
