Feathering not properly working

I thought there was an issue too until I realized I didn't have to hold the button down the whole time it's feathering.

Yes. You need to push the button in for a couple of seconder, then it will lock in until the prop reaches the full travel stop and hydraulic pressure rise and trips it off. (like what happens with the gear and flaps).

I have just tested this on the Channel free flight mission, and it feather and comes to a stop even without changing pitch, throttle or fuel - just by pressing the feather button alone.

 

This is another error in the DCS model, as unless the engine is damaged dead and just windmilling, feathering an operating engine will not stop it rotating until the fuel is shut off.

I still remember some 50 years ago having the DC-3's  THROTTLE - FEATHER - MIXTURE drill hammered into me!

The Mosquito feathering drill does call for the fuel to be cut off,  but its effect is not correctly sequenced.

 

I've given up on reporting Mosquito bugs as my "excessive  pitch up on landing" report is just tagged as  "missing info" regardless of many other agreeing and when all ED have to do is try to do a wheeler landing themselves to get the data!

I still can't do it properly. Sometimes it feathers, just to automatically unfeather a min later, on low speeds. Often enough it doesn't feather at all.


I'm using keys mapped to prop pitch. Do you have them on an analog axis? If so, maybe it's moving slightly which is undoing their position?

I'll try changing the prop pitch on purpose with it feathered and see if I can reproduce.

Thanks I'll test that too.

I use the friction slider on the Warthog for prop pitch, with buttons that modify which prop I'm changing (or both).

I have done the same, but cannot get it to maintain  a small split when moving both. It works but is not perfect.

True Mosquito enthusiasts should have two independent pitch control levers, particularly if ED ever get around to separating the engine audio frequencies  so there is a beat frequency if they are not synchronized.

 

With this in mind, I have started a project to have two small pitch levers stuck to the side of my Warthog throttle (right side and forward).

Unfortunately the Covid lockdowns here have caused massive postal delays, so I am still waiting for some of the bits.

(It took over a month to get some 3D printing filament from one side of the city to the other).

That looks cool. What The you using as sensors?

I am using linear potentiometers moved by the levers to keep the height down to match the Warthog throttle base.

These analog outputs go to a BU8036 devices for the USB output. That is seriously under-utilizing the device, so I'll probably add a few switches on top just because I can.

Perhaps for the mixture and supercharger because they are in the same area. Not essential though, as I have PointCTRL ant flicking switches in VR is a breeze.
