DIY SIM Reliability

Hey guys,
Been wondering about our beloved sims reliability (I am in aviation)
Those of you that have a working DIY sim, what kind of reliability have you seen?
I understand due to the DIY nature, quality control, part selection ect. This plays a major role, but in general how many hours do you get out of your rig before failures?
If you don't mind below describe what failures are common to you and maybe your solution?
Also understand that initially shortcomings are discovered then fixed, with possible long term benefits.
This could prove to be helpful to newbies and oldbies alike.

If your design is sound, its like anything mechanical - give it a bit of a service now and again to grease areas that may need it while also checking for lose bolts/connectors etc and mine is very reliable. Have not done any repairs to it in the 12 months since I finished it.

its as reliable as you build it. you can go cheap and with a bad design and repair often or use good design and parts and repair less often. you say repair I say tinker....

I get hundreds of hours between big breaks now. but just upgraded part of my rig 50 hours or so ago (new wheel, stronger dampers for the weight). no problems since.

so far the only flaw for me is cheap pots I got 2 sets of really cheap ones as a proof that the rig worked but they lasted no time then I got some half tidy ones lasted a while but still broke, picked up a Hall effect set still going strong over a year now, like @bruce stephen said if you build it strong and right they last put cheap parts on there and they will break!!

My one and only break after 15 or so hours was on traction loss. The double nuts backed out causing all the stress to be on the M3 bolt pinning the motor shaft to the 1/2" rod. Obviously that did not last long.
I have since then upgraded all my 1/2" shafts to grade 8 and M4 pins. All should be good now.

Loctite is your friend.

How right you are! Until I used loctite for motors shafts, I had two problems with both motors that even led to broken motors' arms.
And cheap pots as well lasted not too much, giving poor feedback

.... And used Loctite.....

Cheap posts offer cheap results, Quality pots can be LOCKED solid and require a Monster set of plumbing plyers to free up. And guess what, those pots are still alive to this day. Lol


Hall effects = bomb proof.

After a lot of initial gremlins mine has kinda settled down not had to repair it for at least an hour maybe I can get 2 hours out of it soon
