Dmon:
The original dinna have 380's (like the new ones have) it has 280's. You can't even fit 300's in it unlkess you specifically source some short-can units, as the space between the gearbox casing walls is a limiting factor.
I thought someone made an inexpensive twin-motor ESC like the Traxxas unit (think it was Losi) for the eMax (but for a mini-truck) but for the life of me, I cannot find the name. I know it exists, as I've seen it, and have a Rx/ESC unit that has extra slots on the board & in the casing for extra motor leads.
I can take pics of it, but does anyone have any data on this unit (aka web-page or review)??
EDIT: Whoops, Google to the rescue. Its the LOSB0825, a Team Losi Twin-Motor ESC w/Reverse, sourced out of theie Mini-LST truck. It runs about $40 bucks US.
PS: can't find any specs on it, but these 1/18's routinely run 380's (my Mini Inferno's do!)
