Hi Jan...I have the plane and i too had the problem...

I assume you have properly registered the plane

after purchase...

If memory serves me, there is a tool tab, accessible

on the left-hand side of the screen that has some Alabeo

settings...one of those is the culprit...like an open door or

something like that...

Hope this helps...

Great plane...beautiful...

I am using XP 11

and the plane will not fly a flight plan...

Am working with Alabeo on a fix....a popular

on-line fix does not seem to work...failure 

of plane to fly flight plan is a bummer for me...

The DA 40, which I also purchased, will fly

a flight plan...

Hi Donsol...thanks for your reply and you

are spot on about AP not workig well at

or near maximum speed....

Fro further researching this topic on line, 

I prepared the following...the "fix" is from

2012...I tried it on the Evictor and it and 

the speed issue seemed to have helped a

lot...

"First: what is your altitude and airspeed? The autopilot will have a hard time maintaining the altitude if you are flying near-redline airspeed.

Open the X-Plane folder - don't start X-Plane itself.

Open Plane-Maker.

Click on Expert tab at top middle.

Select Artificial Stability.

Click on Autopilot at top middle.

Tick the box at top left: use custom autopilot constants (to undo changes untick this box, close window and save).

Make the changes as I suggested. 

Close window.
Click on File.
Choose Save.
Start X-Plane and see if the autopilot works now. 

In the autopilot settings for X-Plane, change the parameters for the pitch-controller: special/set autopilot constants/use custom autopilot constants. Change to this:

pitch prediction: 2.4 seconds
pitch error for full elevator: 28
pitch response time: 6 seconds
pitch rate: 5 degrees/second."

The above categories have to

be interpreted slightly for XP 11...

I assume no responsibility if the above does not

work for anyone or causes any uninteended

consequences...

Cheers, John H.

Nice plane...good value....using XP-11 and

cannot get the autopilot to hold altitude....

porpoises up and down...if anyone has a

solution,  please let me know...wrote 

X-Plane org about it and no reply..
