There is a mod online, and it is very easy to do.
You’ll need a XT60 Y cable with 2x male and 1x female connection, 2x 4000 MAH 3s Lipo’s and that’s basically it, more on that later when I start the mod.
But, when you do this mod you also need a battery door, and that is what I have ordered!
You can get the file for only $3,- at redpah.com and let it print via 3dHubs if you don’t have a 3d printer yourself.
It will look like this, yes it is bright red!
I can’t wait to do this mod!
