quite easy, both modded and unmodded gameplay..

Note: also happens to all other jet engines, see merged report

 

1. Grab the J-33 Engine
2. Put the engine in the a situation where it was on and then it loses air (or cut air from turning off a inlet)
3. Engine "spools down" and then puts itself in reverse.

Additional Info: it sometimes puts itself back if it double stalls.. annoying and happens a lot on start up on runway/accidental turn ons in space etc.

This bug happens for me too, but it happens with every jet engine! It seems that whenever jet engines receive too little air, they switch mode, so this happens for the Panther engine, Goliath engine, etc. as well!

The rapier does it which makes sense...not so much for the jet engines.

yeah i thought something was wrong with them but I didn't expect nor test all of them, it seems like a bigger bug than what I expected... yes I can confirm all engines do the same thing.. i should have just reported that.

The J-X4, J-404, J-20, J-90, J-33 engines have a bug when sometimes when a sudden lost of air it puts itself in the opposite position of mode/reverses thrust..

 

1. Get any of these parts
2. Turn on engine
3. Turn off intake of air
4. Either three things happen;
   A: It works normally
   B: It stalls the engine and puts it in the opposite position of where it was
   C: It double stalls and nothing happens and it works normally

 

How often it happens? about 80% it did it for me, but when needing to mass test/video it showed they worked only about 20% to produce this bug thus no video will be shown... Need to test it separately.

 

I recently did a bug report with the J-33 but upon further testing, and OTHER users reporting it aswell, i decided to report it..

Moved video from other bug report

@Stephensan Thanks for the new bug report with the extra engines. I have put your video from this bug report into that one.
I can move this to the archive?

Without any further input after toggle the brake and the engines, the Engines put themselve into reverse and back. Happens everytime.

this happens when engines are air deprived. i'm pretty sure shouldnt be air deprived in the first place, but thats a story for another bug report

[Spicat]

@Schnulle, merged your bug report.

Ah, I was wondering why my plane was tipping over as soon as I reached 10km... this explains it. but it's also weird that it happens so fast though, usually I would gradually increase my speed between 10km and 20km and then switch mode, but now I burn up in the atmosphere before I even get to that point

[Stephensan]

This post needs to be merged with 

This bug report has all the air-breathing engines which also includes the j-33. and just tested today, that this bug still affects all air breathing engines, so just do a mega thread instead of one bug report per engine when it affects all.

[Stephensan]

This bug is still active and still simple to test and pull off.

To test it is still the same way the original bug report was reported and they still behave as what the initial bug report reported.
