Brushless motor/ESC combo??

[Bondonutz]

I dont know where your hearing of Castle Meltdowns ?
I can garuantee you 99% of them are from user error (over gearing or low qaulity batterys)

I think pretty much anyone here on the forum will reccomend the Castle befor anything else, The Tekin systems are also doing very well. I'm not saying anything bad about Novak for I have owned many myself but customer care is certainly lackluster with Novak and they aren't nearly as powerful as a MambaMonster combo.

You can't run a single 8.4volt pack in a Emaxx w/any BL system (you could but it'll be grossly underpowered) These systems are designed for 14.8 to 22.2 volts

If your set on running (1) 8.4 pack you'll have to gear waaaaaaaay down to not have issues such as cogging and excessive heat ?

I think more info might help us out more; What exactly do you inspire to do with your emaxx, Make a crawler of some sort ?
