Took the twins out Sat. night through box caynon. First time I got them out and I was not disappointed! Ran about 60 miles in the moonless night and they performed beautifully. Besides almost flipping one (pucker factor of about 10+!) they ran everything with ease. Never had an under power situation. My Jeep buddy drove the other one and even he was impressed (he buying one now). No windshield, so no heat issues (temp was about 100 at start and 80 at @ 2AM finish). I wish I could post some pictures, but running at night it was not possible. Next time I'll post up before hand and get some guys out on a ride.
