parts. I doubt there are many here (if any) that are affected by stuff
this old.
The newer CC47-2 aileron bell crank (to the left of the control column
tube) makes the ailerons more sensitive by extending the long arm from
about 2 5/8" to about 2 7/8" while shortening the short arm from about 2
3/8 to about 2". I don't know when that change was made other than it
was before 1998.
I happen to have a couple of spare newer CC-48-1 mixer bellcranks that
mount on the flaperon arm. Not sure what changed but the center to
center distances of the 1/4" holes are side to bottom 2 1/2" or 63mm.
Bottom to other side is about 2 5/8" or 67mm. Side to side is 3 9/16".
That change was announced way back in a June 15,1992 bulletin.

Thanks Ken,
I'll have to check out the aileron mixer as well.

Measure your elevator bellcrank from the centerling pivot axis to the
cable attach holes.
2.25" means the old sensitive part.
3" means the newer part.
I believe this change was made early although it was some time after
119R which is 1992 vintage. It would be easy to drill new holes and
remove some material to revert to the older style if one decided to do
that later so I decided to go with MAM's recommended specs and see how
it flies.
The 1992 bulletin that changes the aileron mixer was also some time
after 119R came out of the factory. My impression is that they were much
more insistant about making that change.

isCould someone clarify the difference between pre and post desensitized
controls. How would I know which I have? I think the kit I got from Wayne
