I'm creating a model of a glider with retractable engine. And for it to retract the propeller needs to be dead vertical. But now when I shut down the engine it stops in a random position. Anybody know how to make it stop vertical so I can retract the engine. I'm using the Concorde nose animation for the retraction of the engine and the propeller.

I'm using FS Design studio.

For FS-X, I presume?

The "easy"  way is to create a "fixed"  propeller visible only when rpm=0, and set your otherwise prop0_still_key to be visible at rpm>0...

in other words, you'll need to code a new "animation"  say, prop0_stopped for visible condition rpm=0,

and create a second new animation prop0_stillplus, say,which would be a straight copy of prop0_still_key with the lower visibility point at rpm=1

You'd edit the PartDataDefs.txt file in your main FSDS 3.5 folder to define the new part name(s), and of course, add the part information and coding to the modeldef.xml file in the FS-X SDK.


Easy peasey...

Then,. my suggestion doesn't work ...

FSDS 3.5.1 will compile with attachpoint codings - only for FS-X, not for FS9


<back to square 1>

Since you're modelling for FS-9, which version of FSDS are you using?  2.24? 3? 3.5.1?

For an FS9 model you could still create Visibility conditions which would "hide" the animated prop's when the engine is stopped, and display a non-animated, vertically oriented prop.
