@mvacanti in your original email to me you mentioned making use of [measured data](https://www.rcbenchmark.com/) from rcbenchmark using their propeller test stands. In your report you compared the JSBSim calculated data...

@mvacanti when I took at https://www.rcbenchmark.com/ I couldn't find any tests using APC propellers in terms of trying to get some ground truth data for torque.

I've implemented a semi-custom flight simulator using JSBSim. I went with the basic `copy_to_JSBSim()` and `copy_from_JSBSim()` approach. So in the main loop in `JSBSim.cpp` I added calls to `copy_to_JSBSim()` and...

Yep about 3 years ago @agodemar started a repo to redo/update the original PDF documentation as a set of Github pages, so we need to continue the process 😉 https://jsbsim-team.github.io/jsbsim-reference-manual/...

@legoboyvdlp the `bits` field if specified is used to quantize the output, so for example if you specify `10 bits` then you will only see 2^10 = 1024 distinct values...

@agodemar if you think either of the following are useful enough/good enough I could re-do them as Jupyter examples. I originally wrote them up based on running JSBSim scripts and...

What I also noticed is that if I refer to the property without an index then the script appears to take that as an alias for the `0` index, e.g....

@andgi so you're suggesting that you think that `some-property[-1]` isn't supported by the property tree by design. In which case is the `-1` convention as seen and supported by functions...
