I just got a tacon 4420kv motor and xerun 80a esc with a venom 3300mah lipo..ran the truck a lil but due to me rushing I meshed the gears wrong and killed my spur and lost my pinion gear. Anyways I want to know if this is a good setep.. The truck lacked on quick acceleration and died out when floored but would do fine when I rolled onto the throttle ( maybe lack of battery power or to much punch?)...any suggestion for pinion and spur gears and what battery would power good.. I was thinking sky 2s 4000-5000 mah lipo... I'm mostly driving on a sandy track I build in back yard and some onroad... I just got into rc cars but have Ben reading about alot of stufff so I have a general idea. I also want to upgrade shocks servo steering arms stabilizer arms metal tranny gears and driveshalfts. Trucks a horizon hobby torment ecx short course truck 2wd... Any help would be awsome
