Foil pumping using low power efoil

Hopefully the right category.

I’ve got a decent pumping setup with Axis1150 and a small kiteboard. Wondering if anyone could point me in the right direction regarding a lightweight efoil setup.

I’m envisioning not needing the power to get up and riding, rather doing dock-starts, thus the power rating need not be as high as the equivalent wet start, and the large high aspect foil needs very little to keep going.

Familiar with RC planes, e-skates etc, but I’m guessing I’ve maybe missed something. Perhaps a start would be the smallest power unit from the community?

That’s a new track. @JetboardCologne has written interesting posts about efoil setups for sub 60kg riders: small and (really)cheap Flycolor ESC + 6374 outrunner motors.
If you want to collect data, a VESC might be useful.

This motor assist for SUPsurfing might inspire you. The battery should be bigger though.

Ah thanks for the link, the mini motor project looks perfect.

Most appealing is that the components are so much smaller = cheaper!

Any thoughts on this parts list? I don’t think I’ll need 50% of the power in Parts List A, but the price difference seems so minor between A and B that I feel like I could just go with A and have headroom for adding extra cells as necessary?

Parts list A

  1. Brushless Motor 6384 120KV - ~$92
  2. 5-12s 120A Brushless ESC Without BEC - ~$123+
  3. 6S lipo battery ?
    Comments: Same as this this “bolt on” thread, seems 120A ESC appropriate for the 6384 motor. Pulling 60A to get onto foil and 30A to sustain.

Parts list B: Atlernative spec, smaller motor and ESC.

  1. F5085 140KV 650W - $69.00
  2. FSESC 4.12 50A Based on VESC4.12 - $89.00
  3. battery?

Parts list C: Other stuff

  1. Tx+Rx - £30
  2. Prop - will need to modify I guess? Make it smaller? Pitch surely is fine for 100-140kv motors?
  3. Foil with all parts - £1300 2nd hand, currently using this.

Would greatly appreciate any feedback. Key struggle for me is to match prop/motor/esc/battery as I’m used to RC planes where you pop it into a calculator and it will give an estimation of compatibility.

This really caught my attention…
