Starter button = immediate 20% RPM; even without priming


Recommended Posts

Posted (edited)

I noticed this in 2.5.3.21107. Previously the engine would crank 2-3 times, then pause for a second, crank 2-3 times, pause for a second, repeat until magnetos turned on/engine started.

 

Currently, pressing the starter button (or default HOME key) results in immediate 20% RPM, and immediate engine start. Engine can be started without doing any priming at all.

 

Track attached.

 

Reverting to 21106 does NOT resolve the issue. I guess the last time it worked properly was 20601 Update 9.

I have observed the same behaviour, I hadn't tested the module in the previous DCS versions so I couldn't compare but it did seem very odd to see it start like that in 2.5.3.

Seems to still be an issue. In YouTube videos back from release I see the behaviour with the engine cranking a few times before starting, but for me it just starts instantly even without priming and on a cold day. Starts no problem at idle throttle too, don't even need 1/3.

This is still present.

 

Air on. Mags on. Touch the starter and she fires straight up. Very boring.

Me too. Shame, I used ti like the 'reticence' of the engine. Will it? Won't it?

 

Yes exactly.

 

Here is a track showing the bug again. In latest Open Beta.

Thanks Nineline! Good to see this stuff getting picked up. Yak is a great module, just needs some TLC :D

Hi, there's quite a bug there.

 

When you push and hold the starter button with all mags OFF (I mean in both cockpits), the engine starts and there is the engine running sound playing, which is completely wrong. The engine even stabilize at 20% with only the starter, which is not correct. The starter only gives initial rotation impulse to start the engine. If mags are off, no ignition is possible, the engine must just be rotating inconsistently following compression strokes of cylinders with very low RPMs.

 

In DCS, hold the start switch and the engine goes to 20% and hold there until the start switch is released.  

 

I don't feel the need to provide a track since it's so easy to reproduce, but I will if asked to.

 

Can we have a fix ?

 

Thank you very much, have a good day.
