Default Rudder counterbalance locking

Hi,

Reading the following build log:
https://airplanebuild.com/2018/03/15...lance-and-top/

Notice a nifty assembly to prevent the counterbalance screws backing off or the lead compressing etc -as seen here http://www.vansairforce.com/communit...407#post704407

The recent post shows the assembly and also plans behind it - yet the plans I have, and also the plans on the vans site (amendments) don?t show the assembly. Are these old plans and this assembly is no longer needed? (Seems like a better solution than locknuts and future rudder fairing surgery).

Surprising they don't have a spacer under that plate. I made two spacers with good area and tested for reaching the specified torque, it would not torque with standard washers for me. I also used a bed of proseal for good measure. It is a 7 but uses the same weight.

Off topic: I cast some lead weights and found that with a cold mold the lead would pillow like these. If the mold was preheated, the parts were smooth like the mold.

This is the image I am referring to:


Am I missing something that the version of the plans I have doesn’t show such a plate, but just a couple of washers / nuts?

Seems the plate is a better idea to me... than

I received my kit last November and I have the plans with the plate. I do think the earlier versions didn't have this, I did read older post where this was an issue.

My kit did not have plate - wish it did! And I've done the fairings. Hopefully won't have a problem.

I asked about this when I got to that stage in my build:

http://www.vansairforce.com/communit...d.php?t=116779

It really bothered me to have a screw that could never be tightened after the plane was built. I'm glad to see that what I ended up doing is now shown as an acceptable solution.

I just received my kit last week. I am now working on the rudder and I found that there is indeed nut plates supplied as indicated.
I hope they do not come loose.

I?m curious why the elevators were not updated to match the rudder. Does anyone have any thoughts about making the same improvement to the elevator counterweights?

I made backing plates for my elevator counterweights - saw someone else's blog and used the same idea. If I had thought about it sooner, would have done same for rudder.

I also did the same. The rudder had the nutplate plate change and I thought it prudent to incorporate into the elevators as well..
