Got my v1 K8S last week. It came with the v1 Firma 160 of course, 4985 1250kv w/8mm shaft and 23/47 gearing. This is the same gearing as the v2 rtr exb's right? I wasn't particulary impressed by the speed or acceleration, nor was I expecting to be. I had already bought v2 8s rtr takeoffs in anticipation of getting a roller. That didn't pan out, but I have this v2 stuff. So I dropped the 5687 1100kv in, along with a 26t pinion. It's definitely got more acceleration, but kinda flat. My question is, am I missing some power with the v1 Firma 160? I bumped the punch up to 4, left timing at zero. Would the v2 Firma 160 be any better? Any tips?
