I bought a RTR one as seen above and the unknown ESC claimed 125A stopped working in a few days! The motor which is 3600KV has a nice custom sealed water jacket with matching color. The setup can NOT handle 4S because of the high KV motor. I scuffed the bottom gel coat with 400 wet sandpaper.





I then bought an ETTI 150 from OSE and the new motor which is Feigao 540XL 8 turns. With the new setup my radar gun clock 48 mph with 4S 5000 mAh 30C pack.
I plan to go up to 6S, but Steve at OSE suggested the 12 turn motor with the same ETTI 150.

I also added the capacitor bang as seen in the pictures and I took a cooling plate off the broken ESC and attached it to the new ETTI 150 for dual cooling system.
Also note that the second picture shows that I added the water seal foam around the hatch openning and since it is tight fit, I do NOT need the hatch tape any more.

Note that, if one wants to buy this hull for dual motors, it will be a tight fit.

The hull is of a very high quality, plenty of room for 4 or more battery packs. It is quite stable and can handle high speed turn well.
