Hi folks!
I would appreciate some help. I'm trying to rig up the electric trim and
find that I need to trim away quite a bit of metal to eliminate interference
for the full down trim.
I followed Van's instructions regarding the positioning of the trim motor
mount. As you can see from the pictures, though still within the opening
footprint,
the actuating rod turned out pretty close to the inboard edge. (I thought
about centering the mounts at the time, but decided to trust the plans.)
After installing the trim system, there is a slight miss-alignment, but
nothing that would cause stress in the system. I made some marks on the
max, min, and half-way travel of the actuating rod. I then adjusted the
length for no trim at the half-way point.
What worries me most is the amount of metal I have to file out to prevent
the actuating rod from contacting the elevator under max down trim. As you
can see, I've already removed quite a bit of Aluminum. I hesitate to trim
further without some reassurance.
Van's builder's assistance is closed for the weekend, so I thought I would
seek y'alls' help (I recently moved to Aiken, SC, and I'm learning the local
grammar ;))
Thanks and best regards,
Rafael

Dear Rafael,
I had the same problem, till a more experienced builder told me to put a
bend in the threaded rod.
It will lift it just slightly and should give you a little more
breathing room.
Hope that works for you. Sorry I don't have a photo close by to send.

Thanks!
That makes a lot of sense. It's definitely less traumatic than removing al
that aluminum.
I'll try it.

Rafael

Rafael,
My kit came with two sets of aluminum material to make the horn which is
riveted to the trim surface and connects to the rod. One is for manual trim
and one for electric. Are you sure that your using the correct one? I
don't recall having to trim or enlarge the hole for the rod.
