I have an RM20 which I love. HOwever I have a module that I cannot screw in as the left thumb screw just keeps turning. I took a thumb screw out of another module that works in the RM20 and the same thing happens. That module will screw perfectly into my RM50 and RM4.For some reason the RM20 just does not like that particular module. I can put the screw from that module into another module and it tightens right up. I am afraid to use the module with it not completely tightened down. If anyone has had this experience let me know.
