However I’m hesitating since there are way more resources and experiences on the forum about the 65161 than the 70165… Meaning it might be easier to get some help / files or troubleshooting tips with a 65161…
Also finding the right propeller for the 70165 might be tricky no? I’d have to go for a bigger pitch thanks to the additional torque or maybe I’m just wrong
As far as the ESC is concerned, I was thinking about the Flipsky 75200 Pro V2..
Remote will be the Flipsky VX3 Pro
Battery capacity is still tbd… 12S?P
Motor drawings of both motors and it looks like shaft is same so props likely not an issue. Mast clamp STL for 65161 are plentiful here - not sure bolt pattern of the 70165 matches.
The Flipsky 75200Pro VESC has built in Bluetooth. The pro v2 adds a built in power switch and phase filters.
None of this is necessary, but I think Bluetooth is nice for connecting to the vesc with a phone app. Much nicer than a separate Bluetooth module
Also newer Firmware (6.02 vs 5.2) (Can we flash them btw?)
And a switch => Easy security feature already implemented that I won’t have to spend time on
I have been kitefoiling for 6 or 7 years kitesurfing for almost 20 years and efoiling since last year. My advice is to have different setups. Those are complementary sports. My kitefoiling setup is a full carbon board an foil and weighs 13lbs It’s and it’s 13l this is way too small for efoiling it wouldn’t float with a motor and battery but it’s awesome for kitefoiling. My efoil is based on a Flite Pro board and a Flipsky 65161 motor and remote with a Gong foil from 1300 cm to 1600cm I have 3 wings. The 67l pro board is great perfect size for me but riding something a lot smaller would be very difficult. The efoil setup is like 70lbs so you need some volume for it to float. Learning efoiling was pretty different than kitefoiling it took me a few sessions getting up on the board is harder with a kite you have the bar to stabilize you and the larger foil reacts much slower so you have to build a new muscle memory. Efoiling when there is no wind and it’s super warm is great. Sometimes I bring both setups to the beach and if the wind doesn’t show up I can still ride.
Thanks both for your comments!
Following the initial feedback, I’ve decided not to use the kitefoil board and get a dedicated (inflatable?) board like a Gong Hipe in around 110L. I would still use the IC6 foil…
BUT… plans might be compromised now that I’ve found a crazy good deal on some brand new batteries from Takuma (<200€). I believe they are made of Samsung cells.
25ah definitively better but even that’s a little small. Many of us use the LG Robot packs that are 10S 36V 55A/H so total 2.2 KW/H of energy I get between 1 and 1.5 HR with a larger wing than you. You will have about 1 KW/H so half the power but with a much smaller wing you need more power so probably less than 30 minutes at best.
Thanks Windigo for this valuable feedback. I guess to save time, I’ll first try with those 25Ah Takuma for cheap (180€) and if I feel like the range is way too small, I’ll build my own pack based on 21700 Molicel P42/P45.
Following everyone’s advice, I’m now looking for a different front wing, around 1300-1600cm².
I’ve prepared a shopping list
Vesc: Flipsky 75200 Pro V2
Batt : Takuma 25Ah 12S10p
Motor : FlipSky 70165 120Kv
Remote : Flipsky VX3 Pro
Case : Pelicase 1520 / 1550
Prop : That’s the part I’m unsure about… Fliteboard, Flying Rodeo, Pwr Foil, FlipSky…??
Another option to look at is PropellerKing, EU based and made by forum member superlefax.
I think Flying rodeo is always a great option, and they are made of aluminium.
The Flipsky props are cheap, but not really sure I’ve seen much reported about them (good or bad)
The Fliteboard prop is also inexpensive and works well (I have one that I use). It has an 11mm hole for the prop shaft and needs to be drilled out to 12mm. Easy with a drill press, or can be done with this printed drill guide: Flite Prop Drill Guide by Caleb | Download free STL model | Printables.com (I used this and it worked fine)
I tried different props over the years, FR 3 Blade 6” pitch, FR 2 blade 7” pitch, 2 blade from Volker and Flite. They are all good props, my favorite one is the Flite, runs smooth (3 blades) with good thrust for takeoff and high max speed (pitch is unknown but my guess is around 7.5”). Efficiency is also very good.
I use it on a 63100 outrunner with KV 140 as well as on a FR (lift) motor. The 63100 has less torque than a 65161, the FR has more. 70165 should have more torque than a 65161, so it should run fine.
Yo, not gonna lie, your current setup might be kinda sus. The board’s so small you’d have to lie down on it just to get gliding before you stand up, plus that battery box is totally in the way. I’d 100% go for a cheap inflatable board like I did (mine was $290 + $60 shipping). It’s super light, doesn’t mess with your turns, and is mad easy to lug around. Check out my threads for the deets: Components guide for DIY eFoil and Russian͏. Trust me, you’ll thank me later!
Quick update…
I ended up purchasing an F-one Phantom 1480 foil.
ESC & remote have arrived, as well as a JK BMS (B1A24S15P - 150A/300A peak).
I have also sourced the motor to box connectors (Amphenol Surlok) and some XT150 for the battery to ESC.
Next step is to source the 21700… Agree with you Sat_be that 50S are not the best for high current, but since I’m going 10P, they shouldn’t see anything higher than 15Amps max no?
50S being higher capacity and cheaper ($2.7) than molicel P45B ($3.8)…
