I wanted to be able to use AAs occasionally within my Stryfe after modding it for a LiPo. This tray fits inside the stock battery compartment and will fit with the stock cover.

You will likely need to remove some material on the stock battery compartment cover when batteries are added, as the positions have changed slightly and there is interference when being closed completely.

The batteries will not jostle around when closed, so the material being removed is not an issue.
