Danchee Ridgerock Battery Tray Insert

Small QOL part of the Redcat Danchee Ridgerock 1:10 rock crawler.

Switching to standard LiPO batteries caused issues when trying to strap them down inside the battery tray because of a recessed area where the factory battery is intended to sit.
Batteries would regularly slide forward or backwards and then release the tension on the strap and slide out completely.

This simple little riser sits inside the recessed area to create a bridge for longer batteries to sit on that matches up with the rest of the area of the battery tray and raises the tack strip on the battery strap up so it makes contact with the bottom of the battery to hold it in place better.

I've also swapped out the stock battery strap for a shortened standard racing quad strap i had laying around.
