Tony Whiteside over on helifreak came out with this limited edition upgrade for the rush, it will fit the current rush and the upcoming evolution apparently.
I've already ordered mine as it addresses the one thing I don't like about the rush - changing the batteries! You simply load up a couple of trays with the batteries and then simply slot them in or out as needed, securing with a cotter pin.

If you want one, grab it before they are gone (and a spare tray or two!)
