Keep working at it.If at first you don't succeed try try again. That's the only way you learn how to do things.

See that 180 in RED, Boeing ?

That's the turning radius for the steering.....

If you lower that number to
35 - 40.0, your A/C will be a lot nicer to taxi.....

Try it - you'll Like it....

Tried it sc7500, works fine.

But the plane is shaking on the ground and rocking when the tail wheel touches down.

Any tips and tricks?
 
Try this

Sometimes they hop around because the CG Height is too "High":

[contact_points]
static_pitch = 12.233
static_cg_height = 5.907
tailwheel_lock = 0
gear_system_type = 1
max_number_of_points = 7


Try lowering or raising this number in 0.050 increments and see if the hops dissipate...
