Team Losi xxx-nt are very good trucks! I have had one for a while and love it. You will not be dissapointed in your puchase! As for your questions, your truck will never turn good under power. Because of the 2 wheel drive the front end torques under power and you lose most steering. Hence why it is a hard class to run, that and the fact that it will spin out on you if you don't have very good throttle control. Enjoy the truck!
Also welcome to the boards!!
Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light. Though wise men at their end know dark is right, Because their words had forked no lightning they Do not go gentle into that good night. Good men, the last wave by, crying how bright Their frail deeds might have danced in a green bay, Rage, rage against the dying of the light.
