I have had both, Right now I have a rc8 and it is awesome. I did like the losi to thou. Im about 2 seconds faster a lap than I was with my losi with my rc8. The rc8 has awesome corner speed and steering. Althou I have had trouble my fuel tanks as well. I never had a problem with the smoked color, but I did get a new updated white tank. First time out with the white tank I had issues. Flaming out and very inconsistent tuning. I found it was cracked around the nipple. So I went back to the smoked color tank and it has been fine until recent. I having problems with the tune a little, nothing like before before, may not even be the tank. The only other issue I have with he car is the shocks. They are a little hard to build. I blew out two shocks the other day because I guess I over filled them. I will be getting the big bores when they come out thou.
