WingWalker - Right hand position

I am having trouble getting the wingwalkers hand to be placed in the proper
position. my reference_points.cfg is

REFERENCEPOINT.0]
Name=attachpt_wingrunner_pos
AttachTo=""
IsExterior=1
RelativePos=-28.75, 1, -25.8
RelativeRot=0,0,0

[REFERENCEPOINT.1]
Name=attachpt_wingrunner_left_hand
AttachTo=""
IsExterior=1
RelativePos=-27.344635, 3.530001, -25.368459
RelativeRot=0, 2.64159265359, -0.78

[REFERENCEPOINT.2]
Name=attachpt_wingrunner_right_hand
AttachTo="IK_Right_Hand_Target"
IsExterior=1
RelativePos=0,0,0
RelativeRot=0,0,0

I have a IK_Right_Hand_Target node in my blender file and exported to gltf.
But his hand will not go higer than shown. changing relativepos does nothing.
my node is close to the leading edge at the tip of the wing. He is not holding
the wheel. Help.

I feel your pain. Jimmy is seriously choosy about where he puts his hand, and
when he’s not happy he just sticks his arm and hand out sideways. An
alternative technique is not to use a right-hand attachTo node and instead
just tweak the wingrunner_pos XYZ and the XYZ settings for his right hand. But
both techniques are very limited.
