We're starting to get feedback on Sumovore modifications by our customers. Like, turning the Sumovore into a Room-rover. Or 18V motor operation modifications. Or 'Kaoken' double-voltage adrenaline charges when pushing an opponent. All sorts of stuff!
We'll start featuring these modifications shortly, but until then, you may want to take a look at our own Grant McKee's personal page on the Sintra-stiffener hack he's implemented. We're looking at making this a permanent addition to the Sumovore kit, but until then, visit his site for details!
