Walrus in FSX

[Matt Wynn]

Come in number 23, your time is up!

then rack the cocking mechanism on the Vickers just to emphasise the point

... having a break from Walrus today to get some work done for a museum store... oh if you want my kit as it stands just drop me a message and i'll get it over to you :salute:

Having had problems with the floating contact points of the Walrus in FSX, I proposed some changes to Dave Moly & Co, these have been tested, but it would be appreciated if other FSX users would report on their findings in their set-ups. Dave Moly has given his blessing.
There are two versions of a revised aircraft.cfg, one that works (as far as I'm concerned) in both FS9 & FSX, & one that is specific to FSX. The FSX only version has a central point & utilises the wing tip floats, whilst the dual version does not rely on the wing tip floats!
Your comments please through this forum.

Please re-name them to 'aircraft.cfg' in order to use them, saving of course your existing files before doing this!
You will also notice that I have crudely changed the power & wing area so that the engine gives approx the correct HP & the stall speed is now near the quoted values. To help it slow down on water - a FSX problem on all my sea planes- one needs to amend some engine items in the .air file, but I usually press slew (Y) or cut the magnetos.
If you find these changes acceptable, Dave may upload the changes for all users.

Thanks Keith! I can confirm that the "hopping" issue is gone with the FsX only cfg. :ernae:

Bonjour,

"Slow down and stop on the water..."

I also had this type of problem with my seaplanes. There is a solution but you will have to give some gas throttle advance when you start (just a few seconds to get the engine warmed up, then you can ease back on the throttle to its usual 1%). It resides in the following cfg section:

[Piston_engine]
power_scalar =1.00
cylinder_displacement= 125.0 //195
compression_ratio= 7.00
number_of_cylinders= 9
max_rated_rpm= 2050 // with 4 bladed prop. 2475 theoretical max.
max_rated_hp= 750.00
fuel_metering_type= 1
cooling_type= 0
normalized_starter_torque= 0.50
turbocharged= 1
max_design_mp= 35.00
min_design_mp= 10.00
critical_altitude= 4000.00
emergency_boost_type= 0
emergency_boost_mp_offset= 0.00
emergency_boost_gain_offset= 0.00
fuel_air_auto_mixture= 0
auto_ignition= 0
max_rpm_mechanical_efficiency_scalar=1.00
idle_rpm_mechanical_efficiency_scalar=0.65 //1.00
max_rpm_friction_scalar=1.2
idle_rpm_friction_scalar=1.0

The change that I made is in the "idle_rpm_mechanical_efficiency_scalar" which I reduced to 0.65. You may try a little higher settings like 0.70 or 0.75. The right setting should be the one that will get the plane to stop dead in the water after a little surfing from landing in the water...
The setting that I tried does the trick !

Anyone found a cure for the elevators and ailerons freezing when I try to take off from the water ?

Cheers

[Dev One]

Roger, Thanks for that - surprised that the Dual version config does not work though for you! It shows that some setups are more sensitive I suppose!

fleurdelys, Thanks for the idle rpm tweak - that must do exactly the same as my .air file tweak as I have to open the throttle to start with that!
As for the elevator, aileron freezing on take off - that sounds as if a crash has been registered - so maybe the version you are trying is not so perfect - which one are you using? Have you got crash switched off? I must admit that I always have that selected off, so maybe I should try with it selected on!

I experienced this with both files in FSX with crash detection turned off. Although I have crash detection off crash tolerance is set most of the way towards "realistic" reducing crash tolerance to "easy" solved the problem.

 

[Dev One]

cajj - thank you for that response - it was exactly going to be my next question as my sensitivity to crash is set to easy.

Thank you Cajj and Keith.

That did the trick and the Walrus now takes off from the water without any problem.

Is there a seccond version that I might have missed ? I admit that I downloaded the Walrus when it first came out and only just set it up yesterday after reading some of the last postings to get acquainted with it...

This is a very nice seaplane+biplane which are two qualities that really please me in a plane.

Looking forward to the textures that will be available for it...

Cheers,

Fleurdelys

an tAerchór Walrus Repaint uploaded to the outhouse... fs9 and x versions (res) Thanks to Dave and co for kind permission to redo blank textures and repaint her

Enjoyed painting this bird, really well done model.

Just spotted this one. Can never have enough Aer Chór aircraft in my virtual hangar. Thanks,FK!

 

[Dev One]

Fleurdelys & Cajj, I can confirm that if I set my crash realism to 100%, then my controls will freeze, but are OK if set to 50%. I must admit that I did not know that the realism setting was active if Crash was selected off!
Thanks for the feed back guys.

I've noticed that the FSX versions shadow, when sitting stationary on the water flips on & off with the swell, so I'm revisiting the vertical height contact settings to cure that & to see if I can also raise the crash realism threshold. The shadow problem is not apparent in the dual FS9/FSX version! Anyone else see this?

The shadow does disappear when the plane sits at the lowest part of the swell (when the wings are closest to the water) !

BTW, is there a paintkit for the Walrus ?

Cheers,

Just got home after the weekend to find this.. great work, thanks

In my tests.... crash realism lower to stop control locking... bingo, skipping... none. Going to try the 4 fuselage float points vers to reactivate the wake... (as the fuse rides too high for both tip floats to touch the water and thus no wake) is that what you meant by shallow? (no idea of its actual water line)
anyway thanks for the work

 

[Dev One]

FireKitten, Thanks for that response & following your comment re; the wake spray, I have revisited & amended Daves original config using the data gained in these experiments. The attached config is now a 'happy medium' I believe that works for me in both FS9 & FSX.
The engine parameters have been tweaked to help the deceleration in FSX, thats not really needed in FS9 & as long as the crash realism setting is 50% or less in both sims, I find that the controls do not freeze or it jumps about.
Engine starting though needs about 25% throttle until the oil temp reaches about 35°, then one can close the throttle to give about 600 rpm.
Would appreciate any comments from all interested parties.
Dont forget to rename this file before using, saving your old version if you wish.
Regards
Keith

Thank you for the hard work

Report:

Settles into the water much better than before, still struggles to get onto the step, but that might be an aircraft characteristic.
Landing... slows faster, now can actually stop... before throttle wouldnt go below 5%, now it does.

Float points and wheels good, no issues beaching the aircraft or wading, responsive on the ground and water.

Overall, pretty good
Rachael

 

[Matt Wynn]

yup i'm finding along the same as Firekitten a definite improvement, though that 'step' speed is a touch high i feel, you should be Hydroplaning long before then... :salute:

 

[Dev One]

Firekitten & Matt - thanks for your replies - it is really a sort of happy medium to meet Daves requirement for a common FS9/FSX config. As for the step speed - not sure that there is an adjustment, but its interesting to look at it in FS9 from the exterior when its slowing down at about 35 kts as it then seems to sink into the water & decelerate faster. Not so apparent in FSX, so FSX must use a different algorithm.

Keith

 

[Firekitten]

I'd say you hit the nail on the head for a medium ground... Thanyou for the hard work it really means a lot to the community when Developers are prepared to go that extra mile, and we want you to know that we appreciate it, and value it. This is a great aircraft, and its now been fully opened up to a wider audience... More people can enjoy it, and more people can get a little fun from your work
thanks.

 

[Dev One]

Thanks again firekitten - I must admit that finding the correct contact points for a floater is a lot harder than finding those on land. Its doubly hard work & grind for finding them to suit both FS9 & FSX & its just empirical - try it & fly it, so I must have been very lucky when I did my Proctor VI as that seemed easy & It worked OK in both FS9 & FSX as a portover!
I really do like Daves model of this aircraft - I would say his best to date.
Kind regards
Keith

 

[Firekitten]

Well the proctor was straight wheels, and straight float versions right? There's not much issue there. The issue comes with static CG height and amphibians needing two sets of contact points, one out, and one in water. Many fsx/fs9 ports can have the cg height issue, very few seem ok.
