If you go 5S it's more than enough power. 6S is overkill in my opinion. Nice to show off, but useless on the track. 5S is a nice in betweener. with good cells (such as flightpower 5000, or any enerland based pack for that matter) gives you a good 17.5V+@110A load.

Oh, 80 km/h is enough.
But I was thinking that I could lose some weight using 5000 mAh cells insted of 8000, because those are 3s1p and 8000 mAh pacs are 3s2p. And 6 cells that I could get lower kv motor so I could increase runtime. I have experience only 1/18 brushless motors so I'm not sure how much lower kv and higher voltage gives runtime with truck this big. I calculated with Maxamps pacs that if I run 2 x 3s 5000mAh pacs in series vs. 2 x 2s 8000mAh pacs in series I win 100 grams. Only a though...
