[NSRCA-discussion] 18SZ throttle stick limits of travel

[Don Ramsey]

Jim's explanation also applies to Futaba.  I noticed this travel limit on my
Futaba 18MZ so I took it apart and found the travel stop.  After checking on
other Futaba transmitters, I found it on all I checked so, I decided to keep
it installed.

I noticed today while increasing the tension on the throttle stick that it
does not use the full range as compared to the small white marks to the left
of the stick.  The elevator does.  I did not see an adjustment for this in
the manual and did not find anything when looking on YouTube.  Anyone know
if this can be changed?  If there is more sweep available, the precision of
position to response on the airplane would be better.

This is seen on lots of different brands.  Most have a small removable
plastic stop on each end of the throttle stick travel.  If you really feel
the need for extra throttle travel and are up to it, you can remove these
stops.  Just be aware that this can make the stick action at the end of the
travel a little different.  On my DX 20 this makes the stick want to move to
and stay at the full throttle end of the travel when you approach full
throttle.  As I fly mostly large scale sailplanes and use the throttle stick
for flaps I don't find this a problem.

I think this may have been done to avoid over travel on the throttle servo
when you add in the trim action.

Your mileage may vary.
