Hi
Today I finished fitting my empennage (love that word!) to the tail. Per the plans I checked the elevator travel up and down. The up travel is 28.5 degrees versus the 30 degrees required. This will require filing of the F1012D elevator stop and should be no problem.
The down travel however is on 22 degrees versus the required 25. This I am not sure how top correct as the limitation is where the forward push rod connects to the F635 elevator bellcrank located just aft of the baggage area in the tail. As the forward rod travels aft, the F635 contacts the end of the control tube and stops any further movement. The elevator horn still has room to move so that is not and won't be a problem.
The only solution I can think of would be to shift the F1090 control forward by screwing the froward rod end deeper into the tube and the aft rod end out. My only concern would be the amount of thread left engaged by the aft rod end.
Has anyone else had this problem and if so how did you deal with it.
Inquiring minds need to know…
Cheers
Les

Les,
I had to quite a bit of adjusting to ALL the control rod ends in the elevator system to get things to not hit (Other than the elevator stops). Do you have the tail cone attached to the cabin section? I think I spend a couple of hours getting everything just right. There are two bell cranks and the control arm at the front to deal with.

Certainly having the bellcrank hit the push tube, and limiting travel, is not right. The limit should be at the rudder horn. Have you peeked ahead to the section on rigging, to make sure that when the elevator is neutral, the bell crank is at the proper angle?
To answer your question, I've been told the minimum engagement depth for a rod end is 1.5 times the diameter of the threaded end. You need to either safety wire the rod end so it can't back out; or make certain that if you rotate the push tube the other rod end will come tight (all the way in) before this rod end falls out (or I should say comes to less than 1.5 times its diameter of falling out).

Hi Les,If you check section 5, you will find a max and min range for the travel. I don't have my plans with me but I think you are within the acceptable limits. I experienced the same issue until a friend told me to check section 5.

I seem to remember this as well. I think you have a little more flexibility on the nose-down elevator.

Jim
My empennage (there's that word again!), spent about 2 1/2 years hanging from my garage ceiling since being built. Over the past few months I have moved to a hanger, attached the tail cone and have just attached the stabs and elevators / rudder. This was the first time any of these components have been attached.
Using the 91.4 degree template, I first adjusted the front two control rods so the bell crank was aligned correctly.
After attaching the elevators, I adjusted the rear control arm.
As it sits now, the control tube lengths are spot on perfect. The more I think about it and based on the comments received, I need to shift the middle control tube forward so it does not touch the bell crank when the tail is fully down. This should bring the elevator control arm into contact with the forward elevator stop and also give me a few degrees more travel.
Cheers
Les

Hi Dave
I checked my section 5 and didn't find anything related to elevator travel. That being said, I still need to deal with the bell crank being the limiting factor. I agree with Bob Turner's comments in this regard.
If the 28.5 degree up travel is okay, I will avoid filing the elevator stop. I still have about 1/4" clearance on the front stop so I should be able to get the missing 3 degress of down travel. I just hope I can adjust the rod ends enough to make this happen.
Cheers
Les

Hi
Well, I spoke t Van's a few days ago and spoke to Joe who was most helpful. Today I was at the hanger and was able to "adjust" the problem away by moving the center push tube forward so the conical end does not contact the bell crank. IN doing so, the elevator horn now touches the forward stop. Problem solved!
Joe did give me a a "Plan B" in case this did not work. He suggested scabbing an extra piece of AL onto the forward stop so it contacts the elevator horn before the push tube / elevator problem came into play.
Merry Christmas to all.

Hi
Today I finished fitting my empennage (love that word!) to the tail. Per the plans I checked the elevator travel up and down. The up travel is 28.5 degrees versus the 30 degrees required. This will require filing of the F1012D elevator stop and should be no problem.
The down travel however is on 22 degrees versus the required 25. This I am not sure how top correct as the limitation is where the forward push rod connects to the F635 elevator bellcrank located just aft of the baggage area in the tail. As the forward rod travels aft, the F635 contacts the end of the control tube and stops any further movement. The elevator horn still has room to move so that is not and won't be a problem.
The only solution I can think of would be to shift the F1090 control forward by screwing the froward rod end deeper into the tube and the aft rod end out. My only concern would be the amount of thread left engaged by the aft rod end.
Has anyone else had this problem and if so how did you deal with it.
Inquiring minds need to know…
Cheers
Les
