  I know the trailing edge of the elevator is supposed to go  down 35 degrees.  How much is it supposed to go up ?

Zack,

     Is this what you're looking for on page 11-2 of the plans? (Attached)

Jim,



  Oops.  I meant the trailing edge of the trim tab.  My plans says the trim tab trailing edge goes down 35 degrees.  Maybe it's there but I don't see it yet.

This is what I measured on Randy's plane (See also my

message on control throws from January 6th)



Also measured elevator and trim travel.



Elevator: Full up   4.9 degrees above horizontal plane

          Full down 33.2 degrees below horizontal

plane



Trim tab (left):

Full down: 22 degrees down relative to trailing edge

of elevator

Full up: 6.4 degrees above relative to "  " " "



Trim tab (right):

Full down: 21 degress down " " " " " 

Full up:   27.1 degrees up " " " " "



Note: Full up travel is very different for L vs R tab.

Why is full elevator up only 4.9deg compare to the plans? (about 25deg or 

so)

That's a good question. Per tail plans, Full down to

the stops is 25 deg and full up is 30 deg. I am

looking for my original notes but I recall with the

electronic level we were measuring relative to the

horizontal plane for the elevator. If the stabilizer

was at an angle then the measurement would not be

directly comparable to the plans. I don't recall what

the level was with the elevator in trail.



Assuming 25 degrees is full down (and measuring 33.2

deg) this would suggest the tail was ~ 8.2 degrees

down relative to horizontal. Adding this 8.2 to the up

measurment of 4.9 deg would leave you at 13.1 degrees

up (plans 30 deg). Perhaps travel limitations in the

control system limit full travel in the up direction?

It would be worth checking.



Perhaps someone could check on another flying (or soon

to fly) plane.
