About

This mod has been subject to a copyright strike by Aerosoft despite doing nothing more than modifying basic configuration files of a technical nature, non-copyrightable by their nature. Aerosoft's representative has taken to misrepresenting, misinterpreting, and outright lying about our interactions about this to the point that I no longer have any interest in maintaining this mod in any capacity. I thank you for your support. 


Another in the "Definitely Wrong" series of mods!

If you're enjoying this, please keep in mind that this is nothing more than a hobby for me. I do not make money from these mods. With this in mind, any donations are greatly appreciated. Please click here to support me  to support me in my efforts: 

Thank you

Version 10.69 PROP has been updated to work with the new prop physics as well as work with version 1.0.4.0 of the Twin Otter. You no longer need the extra SU8 prop physics file I had here.

The 1.0.4.0 flight model by default have not been changed so this will still work just fine with the update. This have been tested and confirmed.

Installation

I've grouped all of the mods into one pack. Unzip and move the folders you want into Community. 

z-twin-otter-flight-model-mod is Flight Model stuff
z-twin-otter-beltsmoking-mod is a fix for the seatbelts/no smoking switches
z-twin-otter-generator-fix is a fix for the generator number 2 annunciator
z-twin-otter-HSI-mod is a fix for the HSI cross track error
z-twin-otter-sound-mod is to alias the sounds to the King Air

That's it! If you want to get rid of it later, just delete the folders from your community folder. Also, I do not know if this will work with the marketplace version. I have had reports that it does indeed work fine but I haven't personally tested this as I don't have the Marketplace version.

Before anyone asks, these are kept in individual folders for the ease of upgrading for the next Aerosoft patch.

General Dscription:


The Twin Otter is generally very nice to fly but I had a few issues. At low weight you could almost VTOL it with full flap and that's just not right. So I started there and went further, including several bug fixes. Here's what I did:

Flight Model Mod (z-twin-otter-flight-model-mod):

What I've done:

- Modified lift/virtual wing area/incidence
- Reduced lift from flaps

Both of these things work together to change the takeoff/slow speed performance to be much more believable. Expect stalls of 57 clean, 45 dirty when light and and 74 clean, 59 dirty when heavy per the POH. You can also expect the trademark DHC-style nose-down attitude under high lift and especially light weight conditions. At minimum weight with flaps 20 expect her to come off the ground on her own with no rotation. Also expect to push the nose over on landing, touching down at almost a 3 point attitude. For what I'm going for, see  this video showing this behaviour

But no more launching off the ground at full flap at 25 knots!

What else I've done:

- adjusted autopilot to hold altitude/glideslope down to a much slower speed, almost to the stall
- adjusted drag figures for the various configurations to tweak cruise speeds. Expect 170 wheels, 165 skis/tundra tires, and 150 on floats
- increased flap deployment speed from 25s to 15s for the entire range based on videos
- changed sensitivity of elevator for better control at slow speeds
- changed sensitivity of elevator trim for quicker trimming
- changed default position of elevator trim to be up the "up" end of the takeoff range
- increased fuselage side area to allow for better forward/sideslips. On floats it's even more. Have fun!
- changed all seats/cargo stations to be empty aside from the pilot seat and 50 lbs in rear baggage
- Decreased sensitivity of elevator trim overall and at higher speeds. It should be a bit smoother now
- Tweaked rudder sensitivity at takeoff speeds. You'll have to REALLY work for a crosswind takeoff above max demonstrated (27 knots)

Optional Mods:

HSI (z-twin-otter-HSI-mod):

- Changed GPS CDI scaling on the HSI. As a workaround, this will happen with every direct-to waypoint but I'll be changing that so it's airports/approaches only. Per 530W standards expect approximately +/- 2nm in the enroute portion, +/- 1 nm in Terminal (within 30-ish nm), and +/- 0.3 nm in Approach mode (within approximate 10 nm.
- Removed auto-slewing from HSI. You'll have to set that course needle yourself per real life. Unfortunately this has temporarily removed the ability to set an course pointer select while in GPS OBS mode. I fell victim to testing this on my Bravo which worked fine. I'll add a workaround soon

Generator (z-twin-otter-generator-fix-mod):
- Fixed the generator light not coming on with the #2 generator without engine #1 running

Seat Belts/No Smoking (z-twin-otter-beltssmoking-mod):
- Fixes the broken seat belts / no smoking switches introduced in 1.0.3.0

Sound mod (z-twin-otter-sound-mod):

- aliased sounds to King Air sounds.
- If you have this, you do not need my other GPWS mod for the Twin Otter
- The sound mod will only work with default Twin Otter liveries unless you edit the livery's aircraft.cfg file as seen in screenshots.

If you are using the TSS mod or any other sound mod, do NOT install z-twin-otter-sound-mod or it will overwrite your other fancy sounds

This will only last until Aerosoft fixes the sounds in the Twin Otter. Note that this will remove all of the custom Twin Otter cockpit sounds and this is mostly for the engine experience.

These mods should work with all variants of the Twin Otter but kindly let me know if you find any blatant errors in integrating.

Goodbye Aerosoft, I won't buy from them again.

Fight piracy, ok.

But fighting free Mods that improve a product?

Aerosoft just copyright striked this config file mod

might be time to boycott them

https://forum.aerosoft.com/index.php?/topic/171109-ccms-mod-removed-from-flightsimto/

Nice Mod, thanks man!!

One question to the newest version:

Do we still need the SU8 Prop mod extra? Or is it now included in the standard file?

Not sure what the seat/no smoking mod does? How do you bind this mod to any keys/switches?

quick question. is the latest patch ok for WU7 users? Im not currently using the beta

?

I absolutely love these tweaks you're doing! Any chance you'd work on the NextGen EMB-110? I really love flying it with the FTSim sound pack but I'm sure it could use some of your love!

Love this mod! Great work! Thanks a lot.

**You MUST have SU8 beta for this to work** Is that an offical update or only for MSFS Beta testers?

I'm interested in the sound mod only.

Twotter installation from Aerosoft, not Marketplace.

mod "aircraft.cfg" file saved to one of the liveries: /SimObjects/Airplanes/AS_Aircraft_DHC6-300_Wheels_Pax

mod "layout.json" and mod "manifest.json" saved to the root dir of the community folder.

But after launching MSFS no single Twotter is available anymore.

What am I missing?

Hi is it possible for you to incorporate the following into the flight model cfg.

;Gear            1      2     3    4 5    6  7   8    9   10 11 12 13 14 15 16

point.0 = 1, 13.00,  0.00, -6.65, 1500, 0, 1.12, 60, 0.78, 1.80, 0.60, 0, 0, 0, 0, 0, 3 ; Wheel front

point.1 = 1, -2.25, -5.95, -6.63, 3000, 1, 1.28, 0, 0.7, 2.30, 0.60, 0, 0, 2, 0, 0, 1 ; Wheel rear left

point.2 = 1, -2.25,  5.95, -6.63, 3000, 2, 1.28, 0, 0.7, 2.30, 0.60, 0, 0, 3, 0, 0, 1 ; Wheel rear right

I noticed the default aircraft stance from ground is too tail heavy once payload is applied. In real life the plane does not sink that tail low even on max take off weight. It has a particular nose low tail high look. I've been fiddling and i find the points above to be almost the right look. Believe they can be used for the 300 Wheels, 3 blade cargo, 4 blade cargo and skydiver variant. Not to be used for tundra as the actual plane does have tail low look.

Which section has the dimmer to zero on start mod?

Separating them is a great move. Now want to piss off Aerosoft...

Make a HSI fix WITH Auto Slewing...you will get ton's of downloads.

Once the Marketplace update is out I will give it a try and let you know.

FYI...per Aerosoft, there is absolutely no difference in the Marketplace version and all other versions. They say their just store fronts.

Quite happy with what you did. Especially with full flaps behavior on final approach now. Previously without the mod i find it weird that i needed so little throttle for flaps 37 approach i attempted a go around with flaps 37 with 10 knots of gusting wind the plane still climbed without issues and you can delay flaps retraction without any noticeable consequences LOL. In real life the plane will struggle to climb even with max throttle+prop and t5 would be very hot. Controllability would be an issue, it is essential to start lifting the flaps immediately or the go around would be a failure. This mod somewhat brings it closer to the real plane in this regard.

Love the file organization, I was losing track of what I had 😊

Thanks for all your hard work on these mods and sharing. Amazing improvements!!!

Sorry, but I have to critizise some issues: - when the plane (DHC-6-300 wheels pax) is nearly empty (only pilot and some weight in the back = mods default) the plane take off like a helicopter with flaps 1. And when I swich on autopilot it begins to shake and be unstable. I dont know if it is the mod ore since the Aerosoft last update?! Before (with the former versions of aerosoft and this mod) was satisfight but the must be something wrong. I can imagine , that it is a huge work and a good idea, so keep on ! Anyway I keep test it with and without your mod.

Suggestion, bugs and ideas for the future.

  • Version 10.69 PROP March 02, 2022

    Updated to work with Twin Otter 1.0.4 and new prop physics

  • Version 9.69 SQUAT February 23, 2022

    Changed resting position of the normal wheel Twin Otter variants on the ground. You now get that DHC-style nose-down at rest as well as at play. Tundra tire and amphib variants are untouched

  • Version 9.069a Prop February 13, 2022

    This is the prop physics update for SU8 and integrated with the Twotter. This is only for the **-300 Wheel Pax version** at this point but it's a test bed for the new prop physics. Climb rate with two is sliiiiiightly high (1900 vs 1700-ish light), takeoff is sliiiiiiightly fast (600 vs 800-ish feet light), idle prop RPM is sliiiiiiightly low (40% vs 50%), and RPM response to the prop governor is a little aggressive but it's a work in progress so please keep that in mind. At this point we don't have SDK documentation for any of the prop physics so I'm making educated guesses along the way

    **You MUST have SU8 beta for this to work**

    What this does with the new prop physics:

    - prop stuff with the new prop stuff
    - you can feather props and run them slow on the ground
    - you can run at low (really, high) idle and it'll creep ahead just slightly. Be ready on the brakes
    - climb rate with two and one engine is semi-close
    - you can shut one down inflight and watch the prop come to a dead stop
    - you can shut one down inflight and NOT feather it and feel the effect of prop drag
    - you can brag to your friends and family that you have the first version of this mod

    This will work fine along side my flight model mod but it is ONLY for the -300 Wheel Pax version of the Twin Otter at this point. Consider this a teaser. I know things are inaccurate and I'll be adjusting as we go.

  • Version 8.0 SUPER February 09, 2022

    I've added all of the mods into one pack. Unzip move the folders you want into Community. There are no changes from the previous version other than organizing so if you have 7.6969Smokin you don't need this.

    z-twin-otter-flight-model-mod is Flight Model stuff
    z-twin-otter-beltsmoking-mod is a fix for the seatbelts/no smoking switches
    z-twin-otter-generator-fix is a fix for the generator number 2 annunciator
    z-twin-otter-HSI-mod is a fix for the HSI cross track error

    Before anyone asks, these are kept in individual folders for the ease of upgrading for the next Aerosoft patch.

  • Version 7.6969Smokin February 08, 2022

    Added an optional download to fix the No Smoking / Seatbelts switches overheard. These were added as lvars and as such were no longer functional so I've removed the lvar addition for these switches alone

  • Version 7.6969Ultra2 February 08, 2022

    Update to Generator fix mod only to bring back the GPWS Inhibit Switch functionality
