[NSRCA-discussion] Embarrassing Programming Problem

[Troy Newman]

Ron,

I do have some helpful info regarding your trim change with elevator
dual rate. If its not program related....it could be a well worn
elevator gimbal pot.

Tony Stillman can probably speak to this better than...However I did
have it happen many times to me when I was flying my 9Z radios. Radio
South did the fix for me about every 2 years or so. Tony told me the pot
had slipped or was worn...and the "centering" on the sticks was off.
This is why the elevator trim changed with a dual rate flip even though
not conditions or funny trim stuff was happening.

By the way it always happened to the elevator on my radios. I had (2)
9ZAP's and both of them had this problem at various times. I think I
ended up getting the two radios fixed about 2-3 times each...So to me
that was pretty common. Then again I fly too much and wear the stuff
out.

Tony can fix it up in a short order is my guess....or head up to
Pensacola and get Ben to do it for you.


I hope this helps....

I struggled with it and always managed to realize a few days into the
struggle...Oh yea I remember that problem.

Ron,
Are you actually using dual rates within the same flight condition with
the switch or getting the dual rate by going to a different flight
condition? If you're going to a different flight condition, then the
problem could be different trim settings or a different rate of trim on
the second flight condition. It helps to remember that a flight
condition is essentially a whole new model and almost EVERYTHING can be
changed. Your subtrims could be the problem as well. Hope this helps.
