Fixing a couple of fins ( like a shark fish has) at rear end bottom of the boat can reduce the dragging while taking high speed turn.
And I am interested to know the homemade ESC for brushed DC motor.

Maharana, any diagrams for the placements of the fins?
Sahil, details of the homemade ESC for brushed motors please.......

Sir, I have never used fins before but a little experince in sailboats, you have to consider the weight of the boat and judge correct location for fins to reduce the dragging effect and big fins may flip the boat. Also the drag can be reduced by creating multiple lines at the bottom.
