If you are looking for a good motor at a decent price or in your case a trade, this is it. I am a novarossi guy myself but for the money the non tuned grp cant be beat. I know a few racers in my region that have the motor in both truck and buggy and they have no complaints. I was told the only real difference between the tuned and non tuned is a little more run time and better top end. Pull trigger.
