hey guys i bought a used super vee brushless
i have a few questions:

is there lvc on the stock blue speed control?
and i have a problem with acceleration or out of the hole power

if i easy the throttle it goes ok then gets up to speed and hauls ass
but if i gun it like my mystic it kind of bogs for a few seconds then slowly takes off and goes like a bat out of hell, what could that be?

running stock brushless motor and esc
2 2s 5000 40c lipos

any help would be cool thanks
