New here and needed some help.

How many cells are you using?

If it is 14 cells I would reccomend the XL2800 (for speed/power) or for longer runtimes you might want to consider the XL2400.

You could also conider the 9L with 14 cells, as you said you have the money for Lehners and you being a racer need all the performance possible. However, the 10L would be my choice on 16 cells.

The 7XL is for 16, 18 cells but I doubt runtime would be as good as other motors mentioned.
