Ok, now what?

[JOHNNYMAXXIMA]

I'm still waiting for the Super Brain 989's to become available and my new LiPo packs should be arriving any day now. So can someone please tell me if there is anything else that I am going to need to run these on my setup. My setup being the dual 7XL's with two 5s LiPo packs

What I have now (or will soon have when available).......
2 Maxamps 5s LiPo's
2 balancers (one for each pack and charger?)
1 20amp power supply to run both chargers on
2 Super Brain 989's (soon)
2 7XL's (soon)
? ?????

Thanks
John
