NAMC YS-11 BY ESA KAIHLANEN

SOH-CM-2022
Together with Rick Piper's HS 748 and Andover, Esa's YS-ll is one of my favourite twin turbo-props in FS2004. Despite a lot of investigation and checking on gauge up-dates etc, I have never been able to get the engine controls to behave normally.

There is normally a 'feather' of the port prop during intial run up and when pulling the throttles fully back on touchdown. Initiating reverse thrust is just wild and I always opt for hard un-realistic braking and never fully retarding the throttles in order to prevent an unwanted prop feather or the run up of power in forward thrust when it should be in reverse thrust.

Does anyone else get the above situations?

Still fly this a/c a lot as it is a great hand-flyer, but would like to solve the engine and prop management probs.
 
I believe I created a specific profile for the AC in FSUIPC, that works only if you have the registered version of course, and set it so that there was no reverser action from the throttles. This prevents the accidental switching into beta mode, but as long as you are careful you can avoid that zone manually when you go to idle power.

Secondly I edited the blade angle for the beta range to make it a bit less aggressive.

Cheers

From the "Important Notes" section of the manual:
The Ys-11 has an autofeather system which activates when throttle-levers are above 12800 RPM position (marked with yellow "FEATH" markers next to the
throttle levers), and torque pressure is below 40 PSI. It is important to note that if you move the joystick's throttle too fast, you may initiate autofeather! This is because it is possible to move the throttles faster than on the real plane. You'll have to advance the throttles carefully so you DO NOT exceed the 12800 RPM position BEFORE the torque pressure has reached the minimum of 41 PSI.

You didn't say if you are using a separate quadrant or not but this is from the same section of the manual that Tom mentions:

Problems with engine controls? We have only tested the YS-11 with standard joystick type controllers, with no separate controls for prop pitch, mixture, reverse etc. If you are using such a controller (like CH Throttle Quadrant), it's possible that you'll encounter problems. It's recommended that you do not try to use any of those advanced features listed above with the YS-11. The plane (like its real world counterpart) has no reverse, mixture and prop pitch controls. As long as you use the controller as standard throttle, you should be OK. However, we don't have a possiblity to test this, so we can't give you any quarantee.


I haven't flown this plane in quite awhile, thanks for the memory jog, even though the release was 5-6 years ago it was really well done and still holds up today. Now it's time to try it in that sim that shall not be mentioned and see what happens:running::running:.

Oh, nobody here minds you mentioning it; but we're simple folk in these parts and don't understand your new-fangled ways! :icon_lol:

As Tom said (but more politely) this model was one where you definitely had to ****! Now that the actual AFG site has gone the way of the Dodo, Tom's link could be invaluable - maybe this thread could be added to Tweaks & Tips?
 
That fine Gentleman Tom Clayton put me onto this aircraft almost a year ago.

I still owe him a few :icon29:. This is a fine and realistic aircraft.

Maybe not the T&T forum in general since it's more specific to one aircraft, but I'll make sure it wasn't overlooked in the Freeware Gems thread!:salute:

Five minutes later... Post #23 in the Gems thread has been updated with the new link.
 
NAMC YS-11 ENGINE CONTROL.

Thanks all for a shed load of useful and pertinent advice.

Bottom line for me is:

Do gradual throttle changes.

Forget reverse thrust (although a/c cfg is set up for it).

Continue to enjoy a really nice flying medium turbo-prop with some great re-paints.

Talking about re-paints for this a/c, anyone seen any 'Phuket Air' re-paints?

Thanks again guys.
