Since I started it anyway, I'm going to use this thread to share some of my thoughts and further questions re the GF Mk III to Mk IV upgrade:
We already know that Mk IV will get:
- a new Black Box (ver III)
- new/improved clutch design
- spring pre-tensioners
- new grip-to-gimbal connection
VKB have announced a grip-connection upgrade kit and a full upgrade kit, and I was wondering what the full kit will include - and how much work will be required to perform the upgrade. Plus if that full upgrade will be doable for folks like me who would only rate as "fair" when it comes to DIY-skills..

We can assume that the full upgrade kit will require some pretty substantial changes to pretty much all of the interior of the Mk III ...
1. Clutches: Not sure how deep the changes go, but I'm going to assume we'll have to at least swap out the brake-pads. I don't see how we could do any more in-depth work like changing the "barrels", but I'm just guessing here.
2. Electronics: Seeing how Mk IV will come with a new BB and judging from the GF Mk II to Mk III kit, I'll assume we'll have to swap both PCBs on the gimbal?
Both of which isn't too bad, considering you have to mess with almost all of that stuff if you want to, say, re-grease the clutches on the Mk III.
but then comes
3. Spring pre-tensioners. I'm not sure how exactly those will be implemented, but looking at this pic, I think it's safe to assume that the non-cam attachment points for the springs (to the left of the spring in the pic) look quite a bit different from the Mk III's much simpler attachment points:

4. Grip connector would probably be comparable to swapping out a faulty connector-pad on a Mk III-gimbal and routing the cable to the PCB ... plus having to do some additional work on the grip? Not sure about the grip-part though.
In any case and before this gets even longer... I'll repeat my initial questions: Will the complete upgrade leave us with a "true" Mk IV GF after it's done (meaning will all the new features be included in the upgrade)? And is it something a semi-butterfingered individual such as myself can be expected to perform on his own?
Thanks!
