I loaded this a couple days ago and it wasn't working correctly at all. No propeller showing. no thrust. I didn't debug at all. I just now updated through the QT-launcher and it is now working correctly. Really nice in fact.

Pleas help me in solving this problem.
What changes do in need to do in JSBSim, Engine or thruster file.?

That's what I meant: we don't know :)

The problem is in System File i.e. dragonfly-instruments.xml & dragonfly-systems.xml

I disabled this two system files in main JSBSim file (i.e. Dragonfly-jsbsim.xml)
Code: Select all
   <system file="BRS"/>

<!-- ####      Disabled so that it works in FG v2019.1.1
   <system file="dragonfly-instruments"/>
   <system file="dragonfly-systems"/>
#### -->


aircraft loads up in FG v 2019.1.1 & flyable. Only problem is that Air speed indicator & Engine temperature gauge is not working.
Is the problem caused due to "<switch>" tags in instrumentation & system file?

With the revision 20200413 on Linux, and fg 2019.1.2 I can't start the dragonfly anymore :

Is it normal that Flightgear stable downloads WIP models? It misses a versioning? For now, I just can't fly this aircraft....

The original dragonfly did have a special kind of airspeed indicator: a floating plate in a transparent cylinder.
I'd like to re-implement this instrument realistically but apart from seeing it in a video I can't find any information about it, does someone have any references?

That is a hall wind meter. Dead simple design, never fails, no bluetooth, no batteries.

Thank you very much! This was the keyword I needed. I'll promise to bring it back, just a bit more detailed ;)

[EDIT] It's back :D Have fun flying, y'all!
