<DIV>Now I expect all the REALLY old farts to chime in about having to wind up
their rubber-band escapements before each flight. (Bill Glaze?? :-)</DIV>

<DIV>Bill Glaze is off to Punta Gorda Florida where he is judging at the JR
Challenge. Tough job, but someone has to do it!</FONT></DIV>

<DIV>I remember when KPS-14 and KPS-15 were the servos of choice (or PLS-14
and PLS-15 for us Proline fans). Much simpler times. No need for four
digit servo numbers. :-)</DIV>
<DIV> </DIV>
<DIV>My first radio came with KPS-11 servos with the linear output racks.
You know, pull-pull setups would be so simple with linear outputs.<BR></DIV>

<DIV>I suspect the servos he has will be fine if the throws are kept down to
the small amount needed for pattern. However, the control surfaces are
probably much larger than anything on pattern planes back in the 60s/70s, so
the longer moments will be working harder against the servos.</DIV>

<DIV>Third, you may not be aware, but 30 years ago many of us were using
Kraft KPS-12 servos (smallest and lightest!) in .60 cu-in
engine powered airplanes weighing up to 8 pounds. The KPS-12
servo had a torque of 18 in-oz. Think about that for a while.</DIV>
