RE: Cen GST 7.7 or MGT 8.0
GST 7.7 is one badass truck. I have it for many months now and loving it. The torque is amazing and wheelies on demand. It defintiely put the compeitors to shame. I enjoy it because Its bigger, So much more powerful and its different front the rest of the crowd. I dont want to own the same truck everyone at the truck does. The Durability has been awesome as well. I put it thorugh extreme conditions of crash test and GST survive every part of it. Amazing. CEN actually finished 2nd at Roar nats driving 80 minutes straight, that tel you something about the durability.
The servos are mental gear, perfect as a RTR truck but it could use a little more power. I already swap to $200 Airtronics.
I am sure they all do about the same speed, but i would watch out for the 8.0 engine in MGT becuase its a heli engine. the 7.7 in GST is a true rear exhaust engine. Besdies, MGT8.0 just came out so i doubt you will see true long term reports yet.
