MB Modelltechnik battery trays
 

Has anyone tried these battery trays in a pattern plane ?

They make a 'side by side' tray in 2 different lengths, which would be perfect for a 10s (2x5s) flight pack. There are 2 different materials, 2mm CF and what looks like G10/fiberglass?
It would seem to solve the issue with repeatable battery positioning during battery swaps.

I saw these while looking to order a handrest/tray/handle for my Jeti Tx... no affiliation.
