Hi everyone,
I discussed the behaviour with Laminar Research, and they found this out:
************************************************************************
I got to the bottom of this. There is a nosewheel spring constant
entered in Plane-Maker for the IXEG that is NOT in the LR 737.
More details:
1. X-Plane 10 allowed a spring constant on a nose wheel or tail wheel,
e.g. think bungee steering on a C172.
2. X-Plane 11 supports this ONLY for tail wheels - the code for bungees
is a little hacky and doesn't work with the newer wheel physics in v11.
Having proper nose wheel bungees is on Austin's future todo list, but
for now X-Plane only uses this for the tail wheel (true for ALL of v11)
for 11.30 Austin has a wording change coming until we fix all of this.
3. X-Plane wheel steer with differential brakes automagically if the
plane has bungees OR castoring.
So: set the spring force to 0 (correct value for an airliner, right??)
and the brakes will stop braking.
In the future we (LR) may start ignoring this variable if there is no
tail wheel.
*******************************************************
So please try to change this (if you are affected) in planemaker: Opem the 733.acf in planemaker, then open STANDARD/LANDING GEAR and click the GEAR DATA tab. In th top right corner you can see the "nosewheel spring force" - it is currently set to 30. Try to set it to 0 and let me know if this fixes the problem!
If this fixes the problem, we will change this for the next update!
Cheers, Jan
