ESC MHA ratinng

[TomGracey]

What would be the minimum reliable mAh rating for a ESC in a 1/10 th Scale Hydro running a Himax HB3630 1500 Kv brush-less – 6 pole brush-less with a 4s 6000 mAh 20C lipo.

The reason I'm asking is I have a ZTW Seal 130 A/ 2-6s lipo ESC but space in the Engine well is tight and I'm having trouble getting the CG right due to the sizes of the Battery and ESC it would help a lot if I could reliably reduce the physical size of the ESC

Darn sure don't want to burn down the boat because the ESC smokes

Do you mean the current rating? mAh stands for mill-Amp-hour. This is the capacity of the battery.
You only need a 60A ESC for the 1/10 scale motors. The stock Aquacraft ESC works fine for these motors and it's nice and flat.
