i want something with power

i dont care about the fuel economy...

The OS has more power but the Jammin might last a little longer. My OS lost its pinch pretty quick but still runs fine.

if your talking about the os xz28 i think that what it is it either the xz or the zx not totally sure but that motor right there is nothing but power and i was reading in my magazens that the 28 has just about no fuel economy but i see your not concerned with that though ive never seen a jammin motor run but ive seen the 28 from os and that thing is unbelievable for the cheaper prices go to amainhobbies.com they seem to have good prices on there
