how much is the HV system?

It's really a heavy system and it is a real smooth motor besides the feigao or other brushless motor but not real strong. It's a motor that was made to replace the titans for brushless and to have the same or some more speed.

you have to ask alot of questions to chose the right system.

on how many cells do you wanna drive?

offroad track or onroad?

how fast?
