Well my Virpil stick and base have shipped and are scheduled to arrive Tuesday (but I will be happy with any time next week).
And I am getting a bit closer to a resolution with VKB. The updated information on the issue is as follows.
Ron61 on the VKB forums recommended checking the âstopperâ (which is what I think that they call the hex grub screw in the base) and the metal disk. So, back to disassembling the base I go
I pulled everything apart and noted that the stopper grub screw was âlooseâ. I put that in quotes because it wasnât loose enough to be free spinning, but it was only slightly on the side of being anywhere near tight. It wouldnât be loose on itâs own but it only required minimal force to loosen.
Second task, after loosening the grub screw, was to tighten the metal disk. In the picture below you can see that the disk has been rotated clockwise slightly and the two black marks that I made no longer line up. I tightened the stopper grub screw again, reassembled the stick and went about my usualy testing routine.
This time the issue was less noticeable ⊠at least for a while. I was able to fight through the calibration and test it with the VKB Testing app and the âbumpâ was less noticeable. It did start to present itself again, so I put it into a position where it was repeating the problem and then carefully disassembled the stick (hoping to see if I could retain whatever was causing the issue). Take a look at the next picture and note the position of the two black ticks.
Closer together. Hmm. I checked the stopper grub screw and ⊠yeah, it is back to being just tight enough to seem fixed in place. It felt like it was back where it when when I started this testing iteration and it did not feel as tight as I had set it just prior to reassembly.
Instead of doing it all again, I tightened the stopper grub screw (and I will admit that I am hesitant to really crank it tight), put the KG12 (WWII) grip on and began moving the stick around the X and Y Axis. After about a minute I stopped and checked the position of the disk:
It has pretty obviously worked itself back to itâs previous position and, for those curious, the stopper grub screw was again not as tight as I had made it.
So it seems like the stopper grub screw is either not tight enough to hold the disk in place, or the interface between the two is not imparting the necessary friction to achieve the designed functionality. The stopper grub screw is also unable to hold itâs position and if I were to tighten it any more either the tine, thin hex key I have to use is going to bend, or the threads are going to strip.
Moving the stick just off to the side, like I have been doing in the testing seems to be putting just enough off-axis friction to pull the disk out of position. I have a feeling that in itâs normal resting position, the stick forces are straight and level against the disk but if I put a little side throw into it, I have a feeling that a little looseness in the stopper grub is allowing the axis friction mechanisms to come enough out of alignment to âforceâ a movement friction on the disk. Its hard to explain but if you were all here in person, I am pretty sure I could describe it on a white board
I am waiting to hear back from VKB. Knowing Murphys Law*, now that the Virpil stick has shipped, they will probably ship me a replacement part and I will end up with two very expensive flight sticks.
- If you are trying to fix a problem, once you order the most expensive replacement part, a simple solution will be found. Also, if you do order a replacement part, the fix will only happen after it has shipped.
