My JS-2 was dumped off the table at it's first battle day before it hit the field, 'it hit the dirt'. The idler took full impact and was bent exactly as depicted in the photos above. You can see the bracket has been pulled loose from the screw. I removed the screw on mine, bent the idler back and tightened. Fought the whole day and many hours since without issue (I'm sure a certain member will be along to counter that since hull flex is the cause of every evil in the world. ).

If you're really concerned, fill that void between the screw tower and side hull with epoxy making it a solid right angle, construct a simple bracket (steel or aluminum) to span the front and sandwich between the idler stays or simply wait for Guido to work his magic.
