As luck will have it, I happen to own the Hyper10TT which shares common parts and can confirm a perfect fit with no slop and no extra spacers required

A fella on the EB410 FB group found these in his tool box and gave them a try in which he advised the fit was perfect and functioned excellent. Not sure he is on RCTECH thus I had to share with the group.
