Questions about 4 cells touring

[brushless]

As brushless motor becomes more and more powerful (like the new 2.5T Orion motor), I wonder any brothers use 4 cells for fast touring. What are your experiences. Thank you!

And do you think it is necessary to use receiver battery for "4 cells". Thank you very much!:)

I've been using the Novak 4cell GTB brushless system, in the 17.5, 13.5 and 10.5 in pan car oval classes. You only need the Transponder Booster Module if you are using a personal transponder. The regular GTB (fan) is made for 6cell use only and GTB 4cell is only for 4cell use.
