opinions wanted! will 5000 15c 6s zippy packs power a xt8

[tc3_racer_001]

well it works... well! still pulls some wheelies but have settings turned down. pack survived first run no worries. warm but not hot thats for sure! very happy. now have a 30-40C setup i can compare stats with. im also thinking the motor will stay cooler with the 15C packs do to restricted current flowing... not that i can call it restricted. i can tell the batteries are working hard though because after 2 or 3 takeoffs from a standing start they are alot less powerful. i will be nice to these packs now i think - either that or just see how long they last! will attach wattmeter to it tomorrow.
