Bought this off of Basstronics. It is running all stock electrics, I did make a few changes to it before I ran it. Put on a air dam, set strut to 1 1/16 deep and level, set turn fin level and cut the tub to but batteries in sideways running a GrimRacer 40/52 3 blade. I did try a m445 but that was to much for it with the choppy and blew the cap on the esc.
