do we really have to put up with the load this that and other.....every time ?

Do they understand how many times as a developer I restart FG...every night !

Ok I'll work on getting it 3.5 capable tomorrow... looks like there's something now needed in the weights and ballance file, so just a case of starting from the top and working logically to find what it needs...

Hi @bomber

With these changes the Scorpio still gives me a segfault, but now it does so without many of the errors that were listed before

Hi @bomber

I really tried moving around your files in order to get them to launch, unsuccessfully.

As shown above, I did lots of chages that corrected the verbose problems. However, the final error is a cryptic segmentation fault in JSBsim. It argues about the trim, so I presume that either the CoG, or some of the related axis are creating a problem.

(I even tried disabling the System files, but that gave me no change in the segfault)

At this point I am at a lost of how to change this FDM to get it to launch. So I 'll be patient and wait for the best moment to test this fictional helicopter.

ok I see what they've done, they've removed the ability to have negative numbers in a prop power table... wrong.

Without negative numbers the prop wont't free spin, normally that aint going to be a problem on fixed wing planes, if the engine fails the prop will simply fail to spin... still not a good idea as a spinning prop taking force from the wind is actually an increased drag on the plane. So the flight model is now incorrect for non feathering props... because feathering the prop set the blade angle to a position that prevents spinning and reduces drag.

For a helicopter it's a lot worse, because there might come a time when you need to autorotation

https://en.wikipedia.org/wiki/Autorotation

From 2018-3.5 onwards you're not going to be able to do that using a JSBsim flight model, but helicopters are YAsim, so who cares ?

IAHM-COL,

you need to replace the rotor fan in your engine folder with this 3.5 version...

Thanks for troubleshooting

Hi @bomber
I pushed your fixed rotor in 2 steps:

The Scorpio on FGMEMBERS launches now on FG2020.2

I'll let you know my air experience once I figure why I can start engines (rotors OK)
