 Posted: Thu Sep 14, 2006 4:42 am Post subject: Slack elevator cables |
 |
|
I'm too lazy to search it out this morning, but someone recently suggested checking elevator cables for slack in the Mk3. Whoever it was thank you very much, now I think I know why mine has been such a pain to fly. I have an early Mk3, serial number 043 is on the root tube. The cables were slack because the trim cable did not go to the elevator bell crank just forward of the boom tube as newer Mk3's do, but rather went all the way back to the bell crank on the elevator itself. This was not a builder error as the fwd bell crank did not have the tab to hook the trim to it. The effect of the long trim cable was to pull the cable going from bell crank to bell crank until it went slack. This happened at any trim setting other than full fwd. the down elevator cable remained taut, but once the trim was set, up elevator became pretty loosey goosey and you could indeed hold the elevator still and move the stick forward and back at will.

Rick,
I'm happy to have been of help to you in discovering this problem
before it caused you, or the plane any serious harm.
I can only hope all Kolb pilots will check their elevators for
control slack "under load".
Gene,

Gene, I also have to say thank you. After repairing my Firestar from a hard landing, I flew it and the elevator was very sluggish. I checked the cable and sure enough, they were loose. After tightening and a test flight, my sweet old Firestar is back.
Thanks again
