Kdiff3 compare JSBSim output of Rascal and Boeing314 jsbsim example aircraft I can't find why it wont takeoff? throttle up?

I used ctrl + Middle Mouse Button to pull up the menu of xterm and stop the screen scroll to debug the differences of Rascal running in JSBSim vs another JSBSim aircraft Boeing314 has more lines of code and I don’t see the error with what I can see. It allows me to uncheck scroll on tty output. Then I used KDiff3 to look for the differences after copy paste them to a txt editor.

Why wont Boeing314 takeoff?

mode auto
arm throttle

I tried GDB to debug why the JSBSim Boeing314 won’t take off???


Could I have installed them wrong coppying them to the ardupilots aircraft fodler?
Now the unzipped folder is visible by JSBSim and runs the one example.
