for pass 100mph with a 1/8tt you need A LOT of power ......... using "normal" 4p motors of 350-400gr +6s I think is impossible because I tried many times with all the possible gearings and motors (castle, tekin, leopard, xerun etc) ...........
with a mbx5 I arrived at 107mph using a leopard 4282 + 9s ...... next level will be 6s + 5692 motor of 880gr
