I have NEVER had this issue before, but for some reason on two of my airplanes their propellers go kaboom for no reason that I can clearly see.
One of them is a biplane with two fixed +60% props and the right hand one goes boom every time it makes a hard, right turn.
The other is a single engine fighter plane with the guns close to the propeller.
I'm THINKING that for the second aircraft, it's just shooting itself because the bullets just barely pass by in level flight and the AI throwing it around sends the propeller into a bullet.
The first one I don't know. It could be that the right engine is more wiggly for some reason and just barely clips the fuselage, making it go boom? Haven't seen the issue on a left hand turn yet.

No, I've figured it out now. :D
@FltLtFox sometimes does it say it's overspeeding?
@F104Deathtrap
Quite True. XD
@FltLtFox Real life engineers encountered this problem many times. Huge props allowed for better performance, but made takeoff and landing hazardous. A quick look at the long, spindly landing gear of the ME-109 or the strange, bent wings of the F4U-Corsair gives a clue to the compromises that must be made.
@F104Deathtrap
I just shrank the propellers. XD It's still able to fly.
@FltLtFox You can xml the wheels, props or both to disable collisions, assuming you aren't an IOS user.
Wait. I found it. They're clipping the wheels...

I haven't gotten any warning about overspeeding which is what I initially thought was happening, except I wasn't going much faster, and sometimes even slower, than level-flight-max-speed. And the warning didn't pop up.
As for hitting things, I moved the props further away from the fuselage, and they already had about .5 Block worth of space ahead of the wing, and the hard-right-turn-explosion still happened. I shrink the prop diameter and increase the amount of blades to make up for it, still explodes. I've got no clue aside from slapping the engines onto the very outside and see if that fixes anything. :/
The fixed props are overspending, most likely. The other one is probably colliding with bullets. If you place the guns close enough forward, the bullets used to be able to spawn in front of the prop, thus bypassing the problem, (See my SBD3-DAUNTLESS for an example) but that may not be the case anymore. Good luck.
Well, do you get a warning that says "Engines Overspeeding" or something? If so then lower the amount in the fixed.
As for guns, if they hit a prop, the prop explodes. To prevent this move the guns. Or disable collision.
As for anything else, make sure the props aren't hitting anything like part of a wing of fuselage, etc.
Hope that helps
