"This is a new 5000mAh Lipo pack from Thunder Power Racing. These packs are ROAR legal and are available through Hacker Brushless USA. "
Misleading phrase I beleive. I do not think they are ROAR approved, I don't think any lipo packs are in fact approved. They are using "legal" to imply "Approved" which I believe is not true.
This sence of "Legal", of course does you no good during Tech inspection at a ROAR event.
