G2 with 4 cel.
 

What the brushless equivalent?

13.5 with a 1S LiPo.

I would say more like 1s 10.5, my g2 brushless with 4cell is faster than 13.5 even set at 90%.

I believe jay was asking for the brushed G2 equivilant not the G2 brushess 400 size motor.

The "regonized" brushed g2 on 4.8v nominal cells equivilant is 13.5 brushless on 1s lipo (non boosted)

In F1 we use 21.5 on 2s lipo (boosted) as a direct equivilant to the G2 brushed on 2s lipo and they are very close indeed.
So I wouldve thought you could even try 21.5 boosted on cells. Abit of the point but would be quite interesting.

right, done some testing on a dyno
G2 brushed with 4 cell is the same(is) as 15.5 brushless with 1s lipo.
and 21.5 with 4 cell.
Thanks to all who pm'd me with help :thumbsup:
