I'm with Chad. Scale is a blast. The Beast isn't really scale, but I tried! It has a definite weight disadvantage when running it thru chinos at TF, but at Byron it shines, metaphorically. I could drag three of Norm's rigs, sans batteries, thru the course down there.
When I bought my scx10 Honcho rtr, it quickly became my favorite. 3s right out of the gate, I put 2.2 Grabbers on it and raised the top shock mounts to fit the fenders and ran it all over the snow, no problem. Took off the Honcho body and turned it into Clyde.
Now Clyde's drivetrain is under an official GI Joe jeep, a '42 Willys MB2A, if I remember correctly. Brushless thru a metal geared scx10 tranny and an RC4WD 2.17:1 tranfer case and the stock axles...never cracked open. Still running the original dogbones! The scales of this rig is f'n awesome! Two Joes and a trailer full of scale cap, perfect! And damn near perfect in its scale abilities. And I'm sure not only would it finish last, or not at all, I'd probably fubar it permanently!
Just my opinion. If I had to give one up, the XR would go, no question or debate.
