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.
