well, the emaxx's top speed on 6s would be faster.
but the emaxx comes with a pair of 7cell nimhs....so out of the box the avalanche should be faster.
the avalanche is a tad shorter....but it is also wider. So, it may be more stable.
Its also based on a 1/8 chassis.
The emaxx has always had a weakness where the bulkheads meet the main chassis. The only way to solve that is to upgrade to alloy bulkheads.
I dont have 1st hand experience with the avalanche XTE....
but if it were my money, i would get the XTE of the emaxx. IMO, it would provide the same amount of durability and fun for less money.
Most anyone who owns the nitro version of the avalanche loves them. And the XTE is based off that chassis.
