VkB MCG pro springs selection

I know this is very subjective, but those of you flying MCG with the extension mounted, please let me know what spring type selection you made:10, 20, 30, 40, 50

I am using #50 and #20 on each axis.

I was thinking of also adding #20 to my #50 springs.

Closer to the WH Stick with a better Gimbal?

Still a little looser to me than the Warthog, but very smooth and I can feel center better.

Pitch axis still was not as well defined in center as the roll axis ( probably due to the offset extension), so I changed to #30 cam on the pitch.

Pretty happy with it now.

Warthog cam in pitch, 10 in roll. #50+#30 in pitch, #20+#30 in roll. (Not 100% sure on the roll there.) Very little damper, it’s there but not very noticeable. I put some high viscosity gel on the nylon clutch arms, which makes it much less prone to stiction. Nyogel767a.

Thanks for the feedback. I'll attempt the same and see how it feels.

Edit: Completed switch to #30 cams and have #40 + #20 springs on both axes. Feels nice with solid centering and tension is much better for me. Now to fly a bit.

Have fun!

Thank you guys. I never considered adding a second spring (!!!) but i'll definitely give a try. I am currently using #40 because I thought it will help with helicopters. I am trying to find an all arrounder combination that will work to jets, WW2 warbirds and helis.

is 2x #50 on each axis dangerous? If so, what is the recommended maximum?

It's my inderstanding that 2x #50 on each axis is the max. You can do a search on this forum where Uni who is one of the producers said 2 #50 springs are ok. Search here http://forum.vkb-sim.pro/viewforum.php?f=25

Please do NOT use extra stiff springs

I am doing a write up on the VKB GF MCG Pro and for kicks, installed custom heavy duty springs from McMaster-Carr that are about three times as stiff as a #50 spring. Worked just fine, ... nothing broke or bent, but I did not have a chance to test it for months or years. I think the steel cams though can probably take it just fine.

I would explicitly warn everyone against copying this experience, seriously.

Springs' resistance is carefully calculated by not-the-dumbest-in-the-world engineers, and #50 is the strongest for a reason.

There are things other than just springs in the mechanism. Sure thing, nothing will break in a day or two, but this doesn't prove anything - and particularly it doesn't prove that the gimbal will keep working for years (or that VKB will accept any warranty claim resulting from such usage).

We do encourage and support modifications, but not this far.

Using extra stiff springs is clearly a threat to the gimbal mechanism.

can you confirm that the maximum resistance on each axis is 2 #50 springs?

Using 2x #50 springs here also on each axis, using an extension and MCG. Mechanisms been working fine for a year or so now - but I did have the nut come off the pitch cam roller bearing stud the other day, along with the bearing and spacer while flying.

Loud 'snap' and lost spring pressure in pitch - thought I had snapped something, so happy to see it was just a nut fallen off and the cam was pressing directly on the stud threads. Reinstalled nut with a tiny dab of loctite.

I have been using a #50 and #30 spring on each axis for a while now, so far so good and it provides me about the right amount of feel for my preferences.

can you confirm that the maximum resistance on each axis is 2 #50 springs?

Look, there are 2 #50 springs in the set. Why there are no say #70 or #100 springs - neither in the set, nor as an option? Might be for a reason. Why it needs additional confirmation I'm not getting, but OK, I confirm.

Providing #50 springs does not confirm that two can be used simultaneously on one axis. For instance the maximum recommended could have been a #50 and a #40. So no, it is not implied. Its also not in the PDFs on your website.

Most of us here dont want to break a $300 product that took a year to order. Not sure it would be worth waiting another year to purchase again.

I use 2x #50 on both axis. No problems to report.

Beamscanner's question was perfectly reasonable as per his response. Best business practices don't generally involve (trying to) mock your own customers.

I find it seems to be a fairly common trait in the flight sim community...

TWO #50 springs on one axis is OK but not wwithout a warning. Especially when using extension. Imagine what force you are applying to the mechanism given the lever.

The mechanism is as rigid as can be in its compact size, however we expect people to understand that everything has limits.

John can load the mechanism with 2*50 on each axis, and use his joystick for years no problem; Jack would destroy it in a month, simply because of difference in their individual styles (Jack slams the lever at the endpoint limiters with all his power while John hardly ever touches the limiters at all).

Common sense rules.
