Realair Turbine Duke - keep losing right engine!

Recommended Posts

I have the wonderful Duke installed in V4 using the latest installer.

I have the engine settings set to forgiving so expecting no engine failures.  I've confirmed the configurator is working by fiddling with radio layouts and of course open as Admin.

However carefully I manage the power I keep losing the right engine with a loud bang.  I'm nowhere near the engine limits.  

It is now happening straight after take off but a few days ago it happened three times during a one hour flight.  It does restart but that's not the point!

Can anyone give me any ideas what's going wrong please.

Do you have black oil on the engine? like below

Duke is very fragile if you let the temperature (ITT) climb too long.

Maybe you have only open the cowl flaps for the left engine.

Just try to check if the temperature of the engines are similar before the bang

I have the failures switched off.

I have changed P3D so engine stress does not cause damage.

I have the oil doors open.

I cannot get this aircraft above 1500 feet without BANG!

Here is screenshot a second before the latest failure. (Temps and oil pressure green).

Sorta looks like you are pushing that Duke a bit!  Just looking at the 3rd and 4th set of gauges down that column and the fact you are trying to climb at 2,000 fpm. Strange that only one engine is affected.

Looks like a really great aircraft!

It can climb at 3000-4000 fpm and I’ve got it throttled back!

My bet is either a spiking controller axis, or possibly a phantom axis input from another HID controller.  If the mixture axis goes to zero, even momentarily, it'll shut down the engine.  Check your axis assignments in P3D (and in FSUIPC if you use it) and make sure you don't have another controller assigned to the engine axes (throttle/prop/mixture).  If it's a spiking axis, you'll need to clean the contacts, or replace the transducer (usually a pot).

Oh!  

Next flight I’ll disable and disconnect joystick/throttle and uninstall FSUIPC and try flying with keyboard only - that should be fun!

I’ll check all P3D control assignments too but honestly after rotate and gear and flaps up I’m sat watching for it to fail - without actually doing anything- I think. 

Thanks I’ll report back.

You can also use the FSUIPC logging feature to watch the raw values on the mixture axes (you can display them on the title bar, for example) and see if they're moving around when they shouldn't be.

I did what I planned but found two odd P3D commands. Mouse wheel rapid increase and decrease throttle!  Deleted those and it flew!

logging sounds good. Thanks. I’ll report back.

HELP PLEASE  !!

It's not the joystick controller - I disconnected it and flew 'by mouse' and got the same error - right hand engine fails around 1000ft agl.

FSUIPC log shows:

3213828 *** EVENT: Cntrl= 66516 (0x000103d4), Param= 0 (0x00000000) FUEL_SELECTOR_2_OFF

It happens when I'm actually doing nothing - just after gear up generally and I'm watching it climb and waiting for the bang.

But I have no idea why - or what to do about it.

It only ever happens on this aircraft.

Thanks

I believe the engine failure is hard wired into the flight model if you exceed certain limits, so turning it off in P3D would have no effect. This us to happen to me when I first started flying the Duke. Are you flying her within these limits for all 3: Keep this values at or below these and see what happens. Also I would turn back on the damage engine mode in P3D. Make sure the oil doors are fully opened. Good luck!

ITT: 750-800° C

NG: 101.5%

Torque: 1250ft-lb

Do you have fuel in the right tank?  Is the right fuel selector on the floor between the seats set to "On"?

Something is sending a command to shut off the right fuel selector...probably code in the panel.  Also, make sure that no key or axis is mis-assigned to the fuel transfer controls in P3D.
