Hovership under belly battery tray

I didn't like the way many was trying to hold the battery with using the landing skids so by taking a idea from my Trex 450 that I fly hard 3D with I came up with this plus is makes battery changes a few seconds as well as adding a bit more stiffness to the bottom frame and if my battery stays put in my 450 it will in a Hovership

This mounts under the lower deck and is bolted to the frame by picking up the power board mounting holes I taped the holes out in the tray to 3mm you could use self
