I have been contemplating the purchase of a new E-Revo. Doing a search on Tower for "e-revo rtr" I had among the results a 5608X come up. $679.99 and shown as "order pending". As you know the E-Revo brushed is 5603, brushless is 5608 and 5608L comes with Lipo. So I'm assuming this 5608X might be with the waterproof mamba monster? Anyone heard anything? Those prices on Tower are many times cheaper after the item gets in stock, but it's already cheaper than the brushless with the Ni-MH packs. They have a $50 off coupon right now for club members and the usual free shipping. Might hold off and see what the deal is?
