Swedish FE 4S HeatRacing Project

Update Monday November 17 (18.00/6PM): The new draft rules are published - click HERE.

In Sweden we don't race any electric (FE) boats at all. But we have an idea to test some power solutions to come up with a good new FE 4S class for hopefully the 2015 racing season.

This is our main ideas for the new class (so far):
  • About the same size and speed as a normal FSR-H3.5 boat
  • Able to race for the normal 6 race laps on the full FSR oval + some milling time with affordable 4S LiPo batteries
  • Some sort of limit on the motor to prevent it from being too extreme
In the video you can see Claes Meijer's newly built stock JAE 21FE that he bought from Zippkits. The complete hardware kit was also from Zippkits including their 1450 prop. He has used dual parallel connected 4S 3300 mAh LiPo batteries (6600 mAh total) and the run time in this set-up is about 12 laps. The motor is a Neu Castle Creations 1512-2650kv (recommended water cooling jacket) and the ESC is a Swordfish Pro 220A. The overall performance and speed from the motor, batteries and ESC seems to be a good match!

So what do you think - is this the right way to go? :)

Electric is nice and has a long stand time before riding again. Fuel power is much better, fill the tank and go ride. Much nicer.

Hi I use to run 3.5 riggers in the 90's, it became too expensive so gave it up. I've just started testing a 6s set up in one of my old tubs, she's a bit wild but cheap fun. Have come to the same conclusion a 4s is fine for circuit racing,I have started building with this in mind. Did think a shorter milling time would make sense, say a maximum time of 1 minute of mill time.
