Question Grabbing object with hand overrides mass

I am using oculus sdk.
I have a plane.
I have a crank on the plane.
I have a hinge joint connecting the crank to the plane.
The crank has a mass of 1.
The plane has a mass of 500.
When I turn the crank the plane turns too.
This is not what I want. I want to be able to turn the crank and the plane doesn't move. It doesn't seem to matter the mass of the plane. My hand turns the crank and the plane. It seems to override the mass of the plane. I shouldn't be able to move a mass of 500 with my hand. How do I fix this issue.
