yes yes and yes,
at the "Much More masters" on the weekend (540 class) I was running unmatched IB3600/1.17+ GP3300 packs and I was qualifying 2nd all four qualifiers and had a 3rd,2nd,2nd in the finals,
Brett who qualified all first and came first in two of the finals, was running fusion and Promatch 1.19+ GP packs,
we were both running FK05's, the same setup, same rollout and both our motors were pulling almost exactly the same ammout on the MM motor master, even our consistency was almost identical, the only difference was the batterys.
I am looking for 1.19 packs now,
