In hover, left pedal is applied more. It seems correct.

ok so first time she's been capable of controlled flight in over a month... not too bad, managed to land her which is a good start.

Got to work on some bits, but overall I'm confident I might be going in the right direction for bell_pilots realism requirements based on how squirrely she behaves to rapid collective adjustment

ok another observation I need clarity on...

If I decrease the anti-torque with the peddles, this has an effect on the tail rotors m-moment which results in a right yaw with a nose down... and the opposite happens left yaw and nose up.

This is all dependent on the direction of rotation of the tail rotor

So is this correct or the wrong way round ?

regards

Yes, correct. Is she ready for testing?

ok I'm going to package her up for a release...

Yet again this is very much a WIP as I find her difficult to handle, but it might be correct.

my thoughts on this is that modelling the anti-torque response is no easy feat.. the additional m-moment from it adds a lot more complications to the pilots cyclic response.

My FG version is 2020.3.8 and your T4TJSBSim model gives me an error as: "fatal error, illegal argument"
I couldn't test it.
I uninstalled and reinstalled but the error remains.

Ok I'll check my fg version...
