I built a triebflugel thing. Does it count?

That's some fine engineering!

In my case it's because of harmonic vibration: tiny difference in blade thrust together with a little bit too much bearing clearance (to reduce friction) creates a self-inducing wobble, creating the situation of more blades having unequal or loss of thrust, causing the turbine shaft to bounce back and forth. Correct blade angle has a positive effect.

 

Something else: we're back in business!

 

To enjoy helicopters and airplanes like they were in 0.90, you only need to do one thing:

Open the debug menu, click the drag tab, switch off "Apply non-physical part drag at parent CoM"

My plane was struggling to go past 50m/s in level flight. It immediately accelerated to 100m/s. Currently it's climbing at 11km altitude with a speed of 116m/s, blower thrust 5.9kN (it's got 72 Juno's, mind you).

So ... this opens up new possibilities! My next project is trying to create a "tiny" & "light" turboprop with a modest amount of parts and only two blowers.

Variable pitch propellers and engine rpm readout suddenly have become very important!

 

Edit: I was too quick ... it produces NRE's. I'll ask Squad what it means.

Edit 2: a better solution is to just slide the "Global Drag Multiplier" all the way to the left.

So does that have a positive effect on the bearing reliability? I feel they are the weak point at the moment for craft like this.

You can test the bearing yourself, I'd like to see what you think of it. It can still be damaged but usually the engine keeps running. I just had a 1 hour flight with it.
