This is a popular topic at our club as it has become a who has the latest ESC where 12 months ago it was a cell IB or E Power thing.
Honestly its a real pain as at our last clubby my well prepped 416 running SPX Duo2 and 50C packs was left for dead by a TC5 with my old Tekin 17.5 and a TekinRS with the new software and i mean left behind !
This car with a 17.5 was only .3 slower than Antoni Caretti's 10.5 T3
and .5 behind Rhys Marshalls Mod 416
so stock aint stock anymore , some of us think timing advance ESC's shouldnt be used for 17.5 gee i dont know.
Tekin RS with new software is nuts
