This type of chassis must run on 3S........otherwise, a FOAM chassis (remember the old 2008 USA foam spec, 4mm carbon chassis with 3mm upper) 190mm with wide 30mm foams running with hot motor and boost will beat this without a doubt....
Imagine the WEIGHT of this 200mm vs the typical 190mm with foam....that is a big different already.
Overall...I think this is just some engineering and marketing testing, I really don't see why this class will take off.....even 1/8th E format is already struggling due to the batteries, motor to use because of its weight...
