I am going to venture into 1/12 scale and was not sure if I could use my existing esc's.

I see there is a GTB 4-cell from novak. I was just assuming that an old gt7 would work or I have a new GTB/brushless that I was thinking of putting in.

Is the gtb 4-cell just for a smaller foot print or do the larger esc's not really handle the smaller number of cells.

If the later, what other escs would work for 4-cell or (1s lipo, if these are to come out)
