Bob,</FONT></SPAN></DIV>
<DIV><SPAN class=973182121-08012007><FONT face=Arial color=#0000ff size=2>What I
think you want is a slop-free mechanical solution that puts lots of expo in the
airplane,</FONT></SPAN></DIV>
<DIV><SPAN class=973182121-08012007><FONT face=Arial color=#0000ff size=2>then
allowing you to put backwards expo in the TX. That adds resolution and
torque and reduces speed near neutral.</FONT></SPAN></DIV>
<DIV><SPAN class=973182121-08012007><FONT face=Arial color=#0000ff size=2>The
full throw torque is not affected. A pull-pull on a non-circular pulley will do
this.</FONT></SPAN></DIV>
<DIV><SPAN class=973182121-08012007><FONT face=Arial color=#0000ff size=2>I'd
start out with a skinny ellipse pulley wheel at the servo.</FONT></SPAN></DIV>

expo<BR><BR></FONT></DIV>
<DIV>Well, I got a reply back from the company, the resolution is only 1us,
not good enough in my mind. I'll probably still try it, however.</DIV>

<DIV>My first thought was that it would be great with the DX6 radio on
rudder (DX6 does not have expo on rudder as I understand).</DIV>
<DIV> </DIV>
<DIV>But then I thought about using it with radios that do have expo. We
have limited resolution in our systems (1024, for example). In my opinion,
we want maximum resolution around neutral, and once we move away from
neutral then the resolution is not as important (our thumbs don't have 1024
resolution). We can program our radio for 0 expo (or even positive expo on
Futabas) and then use this device to provide expo in our plane. The
advantage is that we (might) gain resolution at neutral which would aid in
trimming the plane and improving the feel around neutral. The downside is
that we would move the full programming of expo outside our transmitter,
where it is easy to do. However, we could still program expo in our
transmitter, it would just end up being a combined amount (this device +
transmitter). But, the "knee" might not be in the same place on each.</DIV>
<DIV> </DIV>
<DIV>Of course, all of this depends on this device having a resolution that
is significantly better than our radios to begin with.</DIV>
<DIV> </DIV>
<DIV>I may have to buy one of these to play with! :-)</DIV>
