In the base rocker mechanism I found an unused hole, and I simply put a 5/16" bolt in, which prevents the chair from rocking. The chair is heavy enough to stay in place on the carpeted floor, and no longer moves at all while traveling. Then just remove the bolt when I get to the CG, and all is again normal.
