Note, the boat in this film is a prototype I built for a friend before finalizing the drawings on the KEP's FE-4S & 4SL Freebie's. So this boat have a turn-fin that is a bit too small = it makes it a bit difficult to keep it in lane #1 with the speed I know is there - one needs to nurse it a bit too much in the turns. Then the ski is a bit too narrow also creating a bit to much load on the motor as it penetrates the drink too much. But note, BOOTH of those items are adressed in the KEP's FE-4S & FE-4SL Freebie drawings.

KEPs FE-4S Prototype

Mikael Sundgren's prototype KEP's FE-4S - here driven with "P-Limited" type of power.

Motor: TFL 36x60 with 2380KV

ESC: Hobbywing Seaking 160A

Batteries: 2x Vapex 4S 2200 mAh in Parallel

Prop: ABC H6

Note, the boat in the video is a prototype built more then two years ago. It's a test-rig that uses our old left-over T2-21 nitro sponsons and ski etc. So the fact that it runs too light on the front sponsons is fixed so to speak to the Freebie drawings that are published.
