Help with simple flexible assist setup to learn pumping on

Hi Guys,

I’ve been reading a lot of post over the past days. And I’ve picked out some parts.
I’m looking to create a add on assist to help me get into pumping. I’ve started pumping on my gong trail v3 1900cm2 and a custom teak board 2 months ago. I might switch to a better learning foil in spring to learn faster. It’s probably too big with the assist anyway.

I want to be flexible and take the assist off later. I may create a new board dedicated to this setup later on. So I want some autonomy and some power.

Current list:

  • |Motor| - Flipsky Waterproof 6384 Motor 140KV 4400W incl folding prop|
  • |ESC| - Flycolor ESC 2–6S 150A|
  • |esc option 2| - Flipsky 60V 150A MINI V6.8 Plus|
  • |Heatsink| - Aluminium Heatsink 100 mm (Black)| (for ESC)
  • |Enclosure| - TICONN Waterproof Junction Box|
  • |LION option| - RacePow Li-Ion 12000 mAh 6S3P| 2x makes a ± 0,5 kWh 12s3p pack
  • |LIPO option| - Turnigy Graphene Professional 12000 mAh 6S 15C LiPo Pack w/ XT90| 2x a ± 0,5 kWh 12s3p pack it’s a bit bigger though. Total cost is lower.

A couple things I would appreciate some help with:

  • Does this ESC and motor combination work? Can anybody recommend one over the other? Ill add a heatsink to the ESC.

  • Same question with the battery. They’re both 12s3p but is there any advantage taking lion vs lipo? I have a battery welder and welded 18650’s in the past but I don’t really want to invest the time and hassle right now so these options seem good alternatives.

  • Any advice on a simple remote? or should I just go with the Flisky 100$ one?

  • any other things I’ve missed?

For the big items should be around 500€.

Here’s a list of parts.

Thanks a lot!

LiPo’s are just a nightmare to work with. The fire hazard in a water environment is pretty high.
In addition you have less usable capacity, as you should not really discharge the cells below 3.5-3.6V.

If you only want to use this setup for pumping, I would reconsider the whole idea.
Pumping a setup with the weight you are looking at, is extremely hard and in my view not fun at all.

yes same here, if you wanne pump go as light as possible and foil as big as possible. 1900cm² shude be ok or you weight is +120kg or so? maybe your board is to heavy to? (looks heavy , massive wood teak? =very heavy )

The main reason to build it like this is to get some more time up on foil, even if it is on motor.
The idea is that the flexibility of the setup allows me to learn now with assist and choose between riding it like a assist board for longer in surf when I get better or take the assist off later to get a full on pumping board. Without having to buy stuff twice.

Board is heavy but only the deck is teak, it’s about 3,5 kg 95cm. I’m 87kg.

for the feeling / learning to stand on a foil i would suggest go get a couple efoil lessons. great fun to do. if you surf/windsurf/snowboard/kite surf before it wil be helpfull to get up quicker but not essential.
or if possible try to hang after a powerboat/jetski/… to get on your board and have the feeling.
i think if you never foiled before it wil be hard learning the way you want to do it (not impossible :hugs:)
for the flycolor esc 2-6s your 12s3p pack is not ok.
i would go all for flipsky (more compatibel i guess)
good luck :crossed_fingers:
