Reply to VC100(vestax) SLOW-HARD CHANNEL FADDERS(HElp!)

I have a question about the fadders, i've seen the channel fadders in action in some youtube videos and i guess they are modded, are them ? i have the vc100 (greyed not modded version stock) and i feel they are too hard to move, is there any mode to make them faster to move ? i tryed putting some lubricant but do nothing ... I like vestax products but they usually have slow channel fadders (not talking about the cross fadder)

Thanks all in advance !
