I am brand new to this hobby & using forums so my apologies if I am not doing it correctly. But I have been looking for the answer to my question for days. I purchased the Team Losi SCTE 3.0 kit & assembled it. I just received my Tekin RX8 ESC but have no idea what kv motor I should get. I am pretty sure I want the Pro4 HD 550, I am using the stock pinion etc. I would like a top end that's fairly fast but I also want it to launch out of the corners and not have a slow-to-wind-up low end. Thinking about racing locally and the only restriction is 2S batteries. Thank you for your input and or pointing me in a good direction.
