I do not appreciate the nut effect. the plane at takeoff must tend to go left as a result of rotation of the propeller.
Effect nut. The motor turns the propeller in a sense so as Newton's 3rd law, the entire plane will try to spin in the opposite direction (action-reaction). Like the vast majority of aircraft propeller rotates in the direction of clockwise (viewed from the cab), the reaction force is exercised on the left side of the plane in the opposite direction to the rotation of the propeller. In addition, at high power while the plane is on the ground (takeoff), this effect causes the left wheel support more weight than the right, which provides more friction, more resistance and increase the tendency to yaw to the left.

This nut effect is hardly noticeable in straight and level flight cruise.

You're talking about p factor

http://www.faa.gov/regulations_policies/handbooks_manuals/aviation/pilot_handbook/media/PHAK%20-%20Chapter%2004.pdf

page 27...

I assume you're unhappy that it's too little, unfortunately there's no measurement of this effect that I can call on as a guide... We just have too adjust the value that produces it, hopefully a pilot with experience would come forward and say "yeh that's spot on"

I suggest with my next update I'll also detail what property in the flight model to adjust, so as you can have a go yourself until you have the right feel....

I am equally happy with Outerra.
I always say you have to go slowly and with good lyrics
any progress is a step towards happiness.

Thanks guys for the welcome back! I really hope to be more active from now on.

Do you know which airport is it?
Milford Sound Airport in New Zealand? :)
Such a beautiful place!

Hi there, and very nice job on the FDM Simon! :)

Here is my version of the Cessna featuring bomber's new FDM and Acetone's sound pack, among other changes and fixes: Download

Changelog:
- New package folder structure.
- Bomber's new FDM.
- Acetone's sound pack (interior and exterior sounds switches according to camera positions and doors state (open/closed)):
    - Wind
    - Avionics
    - Flaps
    - Engine
    - Propeller
- Wing Level AP (turned On when you leave the pilot's seat. Default key: "V")
- Fixed FCS (flight control surfaces) animations.
- Fixed Fuel Quantity gauge.

Note: Due to package folder structure changes, I would recommend you to manually delete the c172 folder in /packages/Levi/ before installing this one.

Simon, apart from the inverted rudder, it seems that I can't steer the plane on ground at low speeds. And even the property to animate the nose gear steering doesn't work anymore. But I guess these issues are easily fixable.

Nice, welcome back Levi!  :D

Your code is indeed way more good than mine for the sounds :) I still have a touch-down sound if you want, but no rolling sound. I have the impression that the rumble is a bit lower than what it should be.

BTW, the sound is not mine but made by Alfredo Fernandes from Dreamfoil Creations. They do a lot of nice heli, so if you have X-plane, you may want to take a look at it :)

You're right on rumble being a bit lower, try this one: c127.js

I've seen the touch-down sound, but since there's no rolling sound, I don't think the result will be too good. I could add the touch-down sound anyways, if you guys want so. :)

Thanks for the welcome back!
The ICAO airport code(NZMF) you put in your video was a good hint to guess the location. :))
Oh yeah, the helicopter. I have to continue working on it...

Now it will not be so easy. there is no evidence, only those who know the world will know to know this amazing place,,, a remote place where the devil lost pants.
Does anyone know of where we talk?

aWac9, that place looks very familiar to me. ^-^

So my guess is: Tenzing-Hillary Airport, also known as Lukla Airport, located in eastern Nepal.


Btw, nice video there, as usual!

Fun part is that it was the first scenery created in Outerra, the blue buildings are from here :)

BTW, aWac9, it looks like you have made a lot of nice locations. Would you like to share these?

Acetona.
for some unknown reason many of the scenarios I've done are very unstable, and are not recommended to install,,,, do not know why I guess sometimes are conflicts of roads, or some mod. especially those of gramofeno etc .. for that reason I have not shared .. but if I want to know do and compress to otx for the community, once they are stable.
send me an email or link on how to do and I send one of my esenarios and your loevalúas,,,, so you see what I mean.
The ideal is to represent the landscape as it is, but I used the island of Agalega as a test of all the mods and maybe you can watch or arrange a nest of conflicts.
