BEEFY is the word!!! Isn't that chassis the sickest piece of RC aluminum you've seen!!?!?!!
One tip I have for you -- when you put the gears in the axle halves, and go to screw them together, they need to "snap" together. You will hear a clack or snap sound when they seat together fully. If not, they will not seem to fit properly and the gears will be loud.
Start a build up thread for your truck too! Or even BETTER do a review thread like this one! I left out lots of stuff like how neat the motor mounts are, and didn't do any side by side shots of the gmade parts next to tamiya parts. That's what I wish I would have done. Like compare the C hubs and see if they are interchangable, compare the wheel axles, drive axles, weight for the assembled axles compared to clod etc... If you don't that kind of stuff I still might...
How much were the lockers? I can't find them on the web site anywhere....
