Posted: Fri Aug 03, 2007 4:23 pm Post subject: Elevator trim rigging

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,

  

 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.

Bevan,  

   

Thanks for your input.  

   

I believe I have the correct type installed.  

   

I also have two sets of horns: one with the provision for either electric or manual trim, and another for electric trim only.    

   

On the one for either installation, there are two sets of holes.  One set, further from the trim surface, is for the manual trim.  The other, closest to the trim surface, is for electric trim.  One is supposed to trim off the excess material for the electric trim installation.  

   

On the other set of horns, those for electric trim, there is only one set of holes and no material trimming is necessary.  When I compare the set horn for universal installation with the ones for electric installation only, the dimensions are the same after trimming the excess material on the dual ones.  

   

Now, if one were to use the manual trim holes on the dual horns in an electric installation, there would indeed be plenty of clearance for the rod.  This makes me wonder why did Vans make the electric trim horns so much closer to the trim tab.  

   

Thanks and best regards,  

   

Rafael

Thanks again, John for your suggestion.  

   

I bent the rod a few degrees and that worked very well.  It not only gave me good clearance, but I was also to correct for the slight miss-alignment.  

   

I now have another question:  I measure a trim control of 20.6 degrees up trim max. and 23.2 degrees down trim max.  Van’s figures, on section 15: Flight Controls, call for Maximum up/down of 25-35 degrees.  That implies to me that a minimum travel of 50 degrees is necessary.  I’m getting 43.8 degrees, so there’s no way to meet these numbers.  It’s all that the motor actuator will give.  

   

Any comments as to what’s going on?  

   

Thanks and regards,

I had the same question when I was working on my Elevators.  I believe somewhere in the electric trim instructions it does say that you can put a bend in the threaded rod.

Hi Rafael,  

<![if !supportEmptyParas]> <![endif]>  

Thanks for the post.  I have just been working on the same thing.  Now I need to hook up the actuating rod and see if I have the same problem.  If it does, I’ll let you know.  

<![if !supportEmptyParas]> <![endif]>  

In the mean time, thanks for making me aware of a potential problem.

Rafael,  

<![if !supportEmptyParas]> <![endif]>  

Well, I checked the actuating rod on my elevator trim system and found that it also had too much interference.    

<![if !supportEmptyParas]> <![endif]>  

I took it all apart and removed some sheet metal where it was rubbing.  Also I used a sander and ground the threads off in the middle portion of the rod so it would not bind if it did rub on the sheet metal.  Now it only rubs the sheet metal in an extreme nose down trim position.  

<![if !supportEmptyParas]> <![endif]>  

If I need that much nose down trip perhaps I should remove the excess weight from my baggage compartment. J

Rafael:

I just got back from a trip and saw your question about the trim travel.  I measured mine today and it is very close to your measurement.  I have 20.3 up trim (down movement of the trim tab) and 24.8 down trim (up movement of the  trim tab) for a total of 45.3.  As I recall from the last RV that I flew you use very little of the trim tab to adjust for approach speed and curse.  I see no method of getting more travel without changing the trim servo. Maybe someone else has a method to get more travel from the servo.  



good luck

Thanks!  

   

That’s what it is and it looks like it will do fine.  

   

Cheers,

I just got back from a trip and saw your question about the trim travel.  I measured mine today and it is very close to your measurement.  I have 20.3 up trim (down movement of the trim tab) and 24.8 down trim (up movement of the  trim tab) for a total of 45.3.  As I recall from the last RV that I flew you use very little of the trim tab to adjust for approach speed and curse.  I see no method of getting more travel without changing the trim servo. Maybe someone else has a method to get more travel from the servo.    

    

   

    

good luck

Thanks again, John for your suggestion.  

   

I bent the rod a few degrees and that worked very well.  It not only gave me good clearance, but I was also to correct for the slight miss-alignment.  

   

I now have another question:  I measure a trim control of 20.6 degrees up trim max. and 23.2 degrees down trim max.  Van’s figures, on section 15: Flight Controls, call for Maximum up/down of 25-35 degrees.  That implies to me that a minimum travel of 50 degrees is necessary.  I’m getting 43.8 degrees, so there’s no way to meet these numbers.  It’s all that the motor actuator will give.  

   

Any comments as to what’s going on?  

   

Thanks and regards,

Thanks!  

   

That makes a lot of sense.  It’s definitely less traumatic than removing al that aluminum.  

   

I’ll try it.

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.

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,
