Mark, good to know thanks. I was lucky enough to pick up a pair from Leo but it still isn't enough gap from the panel. So it looks like I'll be putting a small bend in my sticks (sand filled, capped off, hydraulic press).

Default Grips

+1 for Kevin over at Tosten...

I used Honeywell TL switches in my CF panel, so they protrude farther than most. Using the angled bushings, I was able to get 20 degrees down and 27 degrees up without hitting any switches...barely...

Also, make certain that at full up elevator, it is actually contacting the up stop and NOT something else...like the seat base...

Default Bending Sticks

The factory demonstrator grip hits the panel which is the standard depth. As stated before the elevator up travel is what matters most on the RV-10. Make sure you have a full throw. Also, remember to add weight in the baggage compartment if flying solo, two lightweights in the front (or even with a lightweight passenger in the back if the tanks are full). The factory control sticks have not been changed (even though there is panel interference) because of the greater concern which is the aft travel of the stick. Aim for the minimum elevator down travel of 20 deg as stated in Chapter 15 of the manual. You may believe that a larger pilot may be the worst-case scenario here but a small pilot with the seat in the full forward position may be the critical position to check. For any RV keep the stick full height, IE do not shorten the stick to remove interference with the panel or engine controls.

I am concerned my DAR will have concerns that my elevator travel is 24 degrees down and 29.5 degrees up (limited due to Tosten stick grip).
On the thumb drive it's in the file: 'RV-10 Manual - Main.pdf"

Is the grip contacting the panel, knob, or any other item during the complete range of movement? If so, then there is reason for concern. I asked because you said “limited due to the Tosten stick grip”
I did have to bend my sticks a bit aft to avoid any contact (Infinity grip). The system control stops should be the only motion limiting device.

While I followed this convention, I now think that as long as the stick hits the panel AFTER achieving the minimum specified elevator throw, this should not be something that effects airworthiness. Essentially the panel is becoming the travel stop and every control system has a stop of some sort. Not saying we should allow this, but seems a workable solution, assuming that you have CONFIRMED that there is nothing that can grab and hold the stick when touching the panel.

The applicable DAR would have to make the final call.
Mine did and it would be unacceptable. I believe the issue is that if the stick/grip can contact the (panel or anything else) there is a possibility of getting stuck/caught in the extreme movement areas (i.e. stick hard left/forward can it go below a panel edge or knob and not freely return to neutral). I had already bent the stick slightly and at the inspection there was slight contact. I was able to adjust the push rod slightly to eliminate then all was good.
Again, it would be prudent to discuss with the DAR prior to inspection.

My up elevator is within spec at 26 degrees, but it does not hit the stop with the stick full back. Can anyone tell me where in the documentation from Vans there are instructions for adjusting the control system to optimize elevator travel?

Default Check

Check to make sure the stick isn’t hitting the seat base before the up stop.

Also, check that the pitch servo arm stop is not causing the premature up stop. This was the case on my aircraft...

Here is where I ended up on my final rigging:
https://karrelsj.blogspot.com/2020/1...l-rigging.html

It is possible to get everything into the limits Vans has in their manual. I too had a little interference on my pitch trim servo stop bracket, but that is an easy fix.

My DAR did check for any contact in the cabin. I did not have any (I did bend my control sticks). All of that said, I think an argument could be made for getting my control stick closer to the panel in order to give a little more aileron authority when full aft stick. i.e. I have short legs and flying in the second or third notch of the seat rails has the stick full aft pretty far into my lap.
