First things first, Welcome to the forums! this very setup has been discussed on these boards at one point. I think the setup will be excellent. I run the xl2400 on 18.5v lipo(5s) and it works excellent(I actually dial almost half of the available power out for racing). I will probably go to the xl2000 on my setup to keep the power more manageable. I think the 1600 on 6s Lipo would be an excellent setup, offering nice runtime as well as incredible power. as far as a performance stimate, I guess I will simply say it will be incredible. I have run the xl2400 on 6s lipo once or twice and it is absoluttely rediculous for anything but a speed run! The 1600 should be more driveable, while still offering outstanding performance and runtime.
