Should have checked the temp aftyer a couple minutes after changing your setup. What Medusa motor was this, 36-60-2300, 36-70-2300, or 36-80-2300. 16/46 is very high gearing for that setup. That's about 50MPH when allowing for some ballooning of the tires, 47 without any. I run a CC/Neu 2200kv in my truggy so the kv is close and I run it on 4s lipo as well but my gearing is 54/15. I can still keep up with the nitros on the straight and out power them everywhere else. Problem with your setup is most likely the gearing and an udersized motor. For the cost vs quality I would suggest getting a CC/Neu, $140 from RC-Monster last I checked. And lower your gearing!!!
