G4.5 Beta with F-15 from AddOn 4 Problem

[rocketodd]

During certain points the F-15 yaws violently up and down.

It's called "flutter"...

G4 simulates this with large movements....

Try flying slower or use a thinner wing.

It is flutter, but its not caused by the wing. You dont need to change anything as far as wings and airfoils go.
It's simply adjusting the gyro!!!
Go edit your 15 in the edit menu
go into the electronics menu below the airframe menu
click on elevator gyro
And try this setting. It works flawless on mine. I have my turbine thrust at 24lbs.
Just turn the heading hold % down from 80% down to 50%
Thats it!!! Leave the rest alone.
This should take care of the flutter caused by too sensitive of a gyro heading hold gain mix. Its all relative to speed/thrust of the turbine/model. As you increase or decrease speed/thrust you will need to tweek the gyro settings to compensate.
Let me know how it works out for ya.
Hope this helps!!

Thanks, but this is the default F-15 that comes with Real Flight. I made no edits to the orginial model so KE should change this during their next update.

Understandable!! That stock 15 un-edited has real bad flutter "oscillation". So I did my own changes. But hey they worked well!! No biggie. They have lots of issues with other planes also. I guess its a work in progress.

Wonderful!

I stand corrected!
