[Overdriven]

THe motor plate might be a little thin, I'd run a brace from the top of it to the rollcage bar directly behind it. Then you won't have to worry about it flexing at all when landing jumps, hitting into stuff, etc.

As far as handling more power. Your biggest concern should be the diffs and driveshafts. The driveshafts are the older style sliders, and they can't handle alot of power without twisting up and snapping. My brother inlaws 3906 emaxx with a Novak HV6.5 eats them up in 3-4 runs.

The diffs. From what I can tell, there is no way to access the gears inside the custom rear axle. So if you blow them, you're SOL. If thats truly the case, the most I'd put in this is a Castle SCT system, and I'd turn the punch control way up on that. Think you'd be better off with a vxl or cc4600 on 2s though.

Edit: I'd also bet money that the thin 3906 style emaxx shafts are inside the rear axle "tubes". Again, it looks as if there's no way of acessing the shafts or gears if they break without cutting the axle apart so I wouldn't push it with big power.

Edit 2: Cool truck though. Definitely get us some more pics, especially of the rear axle. And I'm curious to see the front a-arms, looks like they are custom and made of the same tubing as the rollcage
