Well thanks guys, I had another look on the Fromeco site and found this that pretty much sums up everything http://www.fromeco.org/products/06frcjst-640/
Seems as if you can order the balance tap or when purchasing new batteries through Fromeco add a special request to have them add it.
I think I will still get the 10XP, it will be great for all my pattern stuff, parkflyers and foamies.
As for my gassers I'm going to get the new Fromeco simple charger. Looking forward to playing with my new chargers, thanks again.
