Questions?? velocity stacks

Has anyone used velocity stacks on their carbs, such as this http://www.amainhobbies.com/product_...r-Venturi-75mm
it makes sence, seems that it would help an engine that has "low end blues"

when i raced 2 stroke go-karts at pro level we had a heap of diffrent inlet velocity stacks that did a range of diffrent thing to the engine . sum with a high taper/angle heading to the inlet , sum with no angle just a shoulder like a square edge. being that a rc engine is a smaller rotary valve kart engine i reck'n it would work well. for the low price it would be a good back to back .with or with out.
