There was a problem with D-EAGZ, dropped the glider, it didn’t go back to the airport but went to slip into a mountain (I was at LIMW Aosta) and crashed the sim. Now it always goes to slip in but at least the sim doesn’t crash anymore.
If you want to try, I’ll give you the files
I was going to say that. lol Or try the Halo Pelican. 
Tried the DR400-140. Did not work either. 
No doubt there will be some comedian somewhere that is trying to configure the F 18…
I would live that. Can you post them somewhere for download please?
And one more question. I what position in the Aircraft.cfg do you need to add the line “isTowPlane = 1”?
I would also love to have the savage cub as an option for towing.
I put the line at the end of the section [FLTSIM.0]
then I copied the .FLT and ai.cgf files from the default Cessna 172 towplane folder and put them in the plane folder that I want to use as a towplane
anyway, I repeat, I don’t know if it’s the correct procedure but it worked.
Maybe it’s enough just to copy the ai.cfg file… I’m still experimenting
I don’t think the Savage Cub is capable of towing, after all, it’s an ultralight aircraft, it doesn’t have that much power but you can still try.
Please make a backup copy of the original files
Thanks for the reply. I’ll give it a shot!
Oh it should be powerful enough. Ultra lights a commonly used as tow planes in Europe because they’re more efficient than a DR400 for example
Uploaded the first alternative towplane to flightsim.to
It is currently still pending approval
The DC-3/C-47 has a great history as a RW tow plane.
