Yes, I think the Nitro's are built better because of the whole "Nitro is faster" mindset which means harder impacts, etc. However, I think as soon as companies start including brushless systems standard (Losi doesn't count though, since the SS4300 isn't exactly a bullet, and thats a race truck). But once brushless systems are included in stuff like the E-Maxx (or equivilant truck) and such, things will get much tougher.

However, the Stampede and Rusty are the most durable RTR electric trucks if I ever saw one.

Jam, I'd say you can go with a MM4600 oor 5700 on 3S lipo, while keeping the young one to 2S lipo with the 4600 or 5700 if you think he's up do it. This can also be controlled with timing, punch control, and start power. Later on, an easy speed increase will just be an upgrade to 3S.

However, if you do want a T4, a buddy of mine is selling a NIB Factory Team one for a (very) resonable price - I'm actually selling it for him, its in my closet right now lol. Drop me a PM if interested.
