If you experience the "prop pitch bug" in the 109E4

[Insuber]

The bug (or wrong management by the pilots?) in my case consists in the pitch going down low at coarse 8:30-1500 rpm after take off, and keeping there no matter what you do with speed and throttle. If one switches to manual and play a little with the pitch, getting rpm around 2300, and then revert to auto, it works again, but after some 20-30 seconds of hesitation. I don't have identified yet a pattern for the "wrong" behavior.

Cheers.

For me it also sticks at 12:00 and if I dont see it when im diving... blown engine

The problem is that when you spawn on a server (this happens online only), your prop pitch starts dropping down. (E-1, E-3, E-4) If you don't do anything, it will simply drop all the way down to 8:30. You just need to make sure the prop pitch is 12:00 in the take off run, which is part of the pre take off procedure btw.

All these 'problems' are being reported, in my opinion, just because pilot starts the engine and tries to take off on inapropriate propeller setting. The drop after spawn is weird, but it's pilot's responsibility to do all the checks. All you need to do is hit the Increase RPM knob and set it on 12:00. No problems whatsoever.

Nope. In auto, the E4 starts always at 12:00 pitch. T/O is OK. I confirm my description of the issue, prop pitch coarsens after T/O till 8:30/1500 rpm. It works again by doing the procedure described by the OP.

What is the key stroke for auto prop pitch?

I found it as button 3 of the joystick, in options-controls-plane, and changed to fit my h/w.

My point was that there seems to be a weird issue with default position of the prop pitch lever in a Bf 109s (all of them). Offline, it's on neutral as you expect it to be, but if you spawn online, the Drehzahl lever is in 'kleiner' position (lower RPM), which is causing the obvious drop on manual (E-1 and E-3) and perhaps some issues with the E-4, too. On auto, the RPM is also dropping, but much slower. You need to do the same adjustment like on the E-1 and E-3 and make sure it's on 12:00 (part of the take off routine). You won't have any issues that way no matter if you fly manual or auto.

I agree with what you guys wrote and I believe this offline / online business needs to be sorted out and fixed. It seems that everyone is experiencing slightly different issues, I found it quite random - sometimes it works just fine, sometimes I get this drop. Sometimes I spawn online with prop pitch on auto by default, but if I just re-spawn, it sort of remembers the last setting (manual or auto) to start with, e.g. whatever I left it on after landing. Happens only under certain circumstances on some servers. All in all, I believe the prop pitch is modelled correctly as such, but there is something wrong with spawning online.

Also, it might have something to do with the way you control the prop pitch on 109. In my opinion, the usual wheel axis (0-100) on a joystick is not very suitable and I prefer my HAT (returns to the neutral center position like the real thing), that might cause some issues, too.

No problem we are on the same page!

Yep. I noticed that too. Its good workaround untill they fix the issue.

Good point. Make sure you dont have a conflicting AXIS command with a push button command. A while a go I had both an axis setting for prop pitch and a couple of buttons set.
In my case the axis was the rotary on the CH fighter Stick. Unless this was left in the FULL FINE position I got weird effects. Deleting this axis assignment and all is well.

I still get the E3 Prop pitch running to Coarse on spawn, but as others say a quick blip on the Fine HOTAS button stops the prop slewing further and returns it to correct control. Same occurs in the E4 if you select Manual on spawn.

On every start I select manual, set prop to 12:00
Take off in manual when RPM gets to 2300 select AUTO (E4)
