I've got a pre-order in on one right now, but I'm not sure if I will follow through with it and actually buy one.
They don't advertise it as a crawler, just an extreme conditions monster truck. Those tires don't look like they'd be too bad, and I definitely like the wheels. The brushed motor will keep things smooth and cheap, you can get a sensored BL crawler setup if you wanted more power but that'll cost you. The 4 channel radio is nice, other than the switch for the diffs (looks like a cheap RadioShack switch to me). I'm definitely worried about durability. The new shafts should hold up better than the old ones, but you're putting a lot of stress on them with a setup like that. The remote-locking diffs is really the defining point of these things though. This is the only RTR that I know of that comes with them and it will help a lot when the going gets rough. Too bad they insist on keeping their diff design, go with a 1/8th style diff (6-8 spiders including outputs, tough plastic, big screws, etc.). I sold my Revo because there were too many weaknesses, weak diffs were the biggest issue for me. Those battery bays are also too small to be running a big lipo...the more I think about it the more I think I should cancel my order
