EGT

Is this abandonware already? No comment from the devs?

Some more bugs: * Battery overheat test doesn't work * HDH mode (heading hold?) doesn't work as expected. Expected behavior: capture heading at moment of AP engagement * DME speed and time stops working and displays zero, or constantly counts from zero to the value then resets to zero * DME speed and time sometimes only reads zero regardless of changing frequencies, etc. * Some switch have the wrong number of positions (e.g. some 2-position switches have 3 positions) * After the first engine start, BOTH start lights illuminate with second engine start * Engine spool time/EGT peak is unaffected by battery health * GPU start current limiter has no effect

Hi, The aircraft is pressurizing regardless of how I set the panel. I also seem unable to manually control the cabin pressure, or even intentionally depressurize in-flight. It also seems the oxygen system and masks are not modeled (function thereof)?

I think the developer has abandoned the project. He hasn't been on these forums for months.

Fair enough! Would be better if there was an option for "service gear" when parked/shutdown to avoid a sim restart though...

The developer last visited this forum over 3 months ago (April 2025) so not hopeful of any updates to the MU2. There is nothing we can do about integration of the TDS into the aircraft as it requires modification of the model to do this.

Hi, After playing with the energency gear extension, I was unable to reset the system so the gear could be retracted as normal. Handles were reset and normal gear handle moved from DOWN to UP. Hydraulic caption appeared to show running, but gear did not move. Apparently no way to reset the system without restarting the sim.

Hi, It seems somes audio is missing: * DH altitude alert * Engine fan at TO thrust * No gear noise from retract/extend * Wind noise seems to be lacking (it sounds the same at 250 kts as sat not moving) * AP disconnect sound is extremely quiet

In the latest release (as of July 4th 2025) I also see phugoid behavior in IAS mode, to include descending. It takes too long to stabilize, and the pitch changes are too fast and too much to capture the speed. VOR tracking is also a little suspect. It will wander +/- of track before finally getting on course. Tested using a VOR on an island from 100 NM out. It will "get it" after 2 small overshoots of the course. It takes it about 5 minutes to stabilize.

I'll check it out again. I have two controllers, and I'm not using any other software between them and XP, so XP is using the raw inputs. I'll also check the keybinds again.

Hi, Is the engine modelling outside of X-Plane? When setting the condition levers to TAXI in the Beta range, EGT rises from 200-300 deg. C to 700 deg. C. Seems rather hot!

Hi, As I understand it, the 750 and 650 should only be powered when the radio master is ON. As it is, the 750 powers the second battery power is available, and there is no way to switch it off.

Hi, I tried to map the key bind for single condition lever "toggle between EMER and TAXI", but it does not do anything.

Hi, There are a few problems with the setting UI: * It doesn't like scaling factor (Windows is set to 150%) and so draws half off the screen (top half of the window is cut off). * Option to place the inlet covers is missing

Hi, I'm using a hardware throttle (TM Warthog throttle) which is mapped using standard axis in XP11 as per the recommendations in the MU-2 documentation. The throttle is a single throttle mapped to Throttle 5, and the other throttle is mapped to prop lever (PROP) as stated. The option "manipulators with hardware" is UNCHECKED. There is a serious problem with how the HARDWARE is interacting with the sim. The throttles and condition levers are working correctly IN SO FAR AS the animations, detents, etc., and working, and I can operate the THROTTLE detent via a button on the throttle to lift the throttles. Basically the bugs as I can see them relate to how the MU-2 handles hardware input, in addition to several missing or malfunctioning features. First, the throttle: * Moves the levers as expected * Gate works correctly * Button to lift throttles for single-lever hardware works However... the engines do NOT respond to the throttle. Second, the condition levers. * Moves the levers as expected * Gate/toggle does NOT work However, again, the engines do NOT respond to the hardware! This also makes it IMPOSSIBLE to start the engines using the normal procedures AT ALL. The workaround. Before starting the engines, the levers MUST be moved USING THE MOUSE to TAKEOFF/LANDING then they can be operated with the hardware throttles. Failure to do this results in the engine system thinking the condition levers are still in EMERGENCY/FEATHER position when they are NOT. Levers in the cockpit are moving in response to the hardware when this happens. A similar problem exists with the throttles, however that bug relates to the setting of "use manipulators with hardware". The manipulators MUST be disabled, otherwise the engines totally do NOT respond to either throttle or condition lever input. After I figured this out I was finally able to go flying, but it rather soured my initial experience with this aircraft.
