BRXL Vs. Sidewinder Comp and Scale?

[alexchen86]

I have a waterproofed HH BRXL on the way with a Torque Master Pro 35T handwound combo. I plan on just soldering the motor to my AX10 comp rig using my existing Sidewinder ESC with CC BEC setup.

The HH BRXL is waterproofed and will be going to a new broken in 55T Integy Pro Lathe on a Honcho. I want a cheap motor on it since it will be seeing a lot of mud and water. The reason I went with the BRXL is so I can have the ability to run 4S on the Honcho as a 1.9 TTC.

Will I see that much difference in power between the two ESCs? My main concern is the ESC being waterproof. I also know the Sidewinder can handle up to 4S but it doesn't like it especially during hard comps.
