    I own the Nero Big Rock and I would like to use it for both - for bashing and for crawling. I've already increased the ground clearance and mounted Outcast tires.
    What do you think about installing a sensored motor? Would the Nero crawl like the Summit with its brushed motor? Have any of you tried to drive the Nero with a sensored motor?

    The Summit has a two speed gear box so I think it will always crawl better than the Nero. Also big sensored motors are not very common and of course you also need a different ESC. So I wonder if some Nero owner is switched to sensored.
    Just wondering how did you increased the ground clearance? The Outcast tires look cool on the Nero!

    I have thought about this before. What would really be best is swapping the center diff for a two speed tranny. Either from a Summit or possibly a Axial Yeti XL?? Let me know if you do it!

    Thanks for your answers. I already have a hobbywing Xerun ESC and I was thinking of a Turnigy 4270 motor from HK.

    To increase the ground clearance I just adjusted the shocks to the middle holes and extended the push rods with two washers under the rod ends. Also I increased the preload of the springs. So, not a big deal. But you have to take care of the drive shaft rubbers which start rubbing on the upper A-arm when you exaggerate this.
    Yeah, the Outcast tires are really outstanding. Perfect traction and no ballooning. Much better than all the tires I've had before.

    I have the castle mmx/2200kv sensored in my savage flux. It's very smooth at a crawl, although I never drive it at crawling speed. I only got it because I wanted a waterproof system vs the old MM version of the esc/motor I had on there.
