Here's a quick EagleTree in which I flogged it as hard as I could to see how many amps it would pull under stress:
Not bad, eh? It allows for use of Blade CX2 packs and the like.
Improvements:
-It rides high, so I'll probably limit the shocks.
-I'll put the battery on the front servo.
-I might put a tad bit of weight in the front wheels.
If you have any questions or want more pics of specific things, just let me know.
Seriously, I've had several crawlers and this one might be my favorite already.
