See that's my thing- I don't know if it means 7.2-12V/18A- OR if it is a 7.2 volt motor with a 12v/18A ESC. This is where I am stumped. I don't know how else to mount the lipo, I may just end up using spit stick packs since that is all there is really room for. With the batery in the rear, it ran fine up on plane, but low speed stuff was scary- as was any little wave it would hit lol.
