Hahaha, nice. Yeah, ROAR compliance is tough (to be fair, they're only evaluating packs that are sent to them). I know the 3s TP is ROAR approved, so I may have a work around purely on the fact that I'm running 2 ROAR approved Lipos at one time (I'll have to bug a ROAR rep on that one). I think the only restriction may be that I can't charge them both from a single charger at the same time. I dunno, I'll have to look into it. Either way, I like the idea of keeping my stuff cool. Temps play way too big of a roll on these big 1/8 brushless systems.
