So my 2 sons are bored with their stock stampedes already. They want to go faster. Iíve heard mixed opinions on using LiPo batts in these stampedes. They have the base model 2wd brushed version. Will lipos be pointless other than battery life? Or will they give them some extra speed/punch? Considering buying the brushless motor and esc to upgrade them in future but not this year. So Iím wondering if going to the 2s LiPo batts right now is worth it for these trucks. Or if Iím better off waiting for the total upgrade next year with the brushless motor/esc, and just buy the lipos then.
