Hi All,
Keen to make a DIY efoil kit for my wing board. Very much a beginner and only just learnt to tow foil. Keen for the Efoil mod so I have more options to get out.
I have in my cart ready to order.
Flipsky 65161 motor, FSESC 75200 (200a / 300a max) Flipsky VX3 remote.
Im about 95kg got a 145l Inflatable board and NSP 2500 front wing. So on the big side of everything I have some big 6s lipos for some RC stuff. So planning on running 12s
Questions are.
Does this sound like a reasnoble starting point.
The motor sounds big, 6000w. Next one down maybe only 3700 so maybe too small? Maybe the big motor is more forgiving and easier when learning ?
Was thinkng fixed prop and a prop guard. What size prop would you use on that motor ? Looks like a 100 and 120kv motor options. Not looking for max speed. Just need something to get the big gear up
Sounds like need to keep those remotes in a plastic bagâŚ
Any other tips or suggestions greatly appreciated.
Cheers
Making an efoil of of an old wingfoil board is possible, but youll be ending up with a battery box on the back of your board (highly annoying). Further, the 65161 is a good choice, vesc is also good, you can use the propguard that comes with the motor (i think flipsky sells them) and the white prop that you can buy with the 65161 is also a really strong one with a lot of torque (but you need to balance, as its very wobbly out of the box). If you end up getting the hang of it you can just remove the guard making it more fun to foil. But id personally hate to have a big ass box on the top of my board, and id make sure the lipos you are using are capable of delivering enough current.
With these values a 6384 motor will also be enough to fly while being lighter and smaller. But will limit you to 3-4kW later, so max speed maybe 35kmh. With a 65161 Max speed will be >50kmh, you will be limited by other constraints other than power. If you are unsure buy big. 120kV/140kV recommended. Propeller either take the white flipsky or have a look at propellerking.com for some efficient props.
75200 VESC is a good choice
I second the fact that an electronics box is annoying, but also it is the quickest and cheapest way to convert your board, so maybe worth a shot, learn from it, build the âperfectâ board after that
If you want a remote thatâs very waterproof and has diy repairability in mind, check my BREmote diy kit
Awesome thanks for that sounds like should be half way on the right path. Yeah totally agree the battery on the board will be a pain. But will make do with what I have to get up and going and fine tune from there. Maybe modify a hard board or make a new one.
I have 4 4500mah 6s 90c Lipos. So will connect 2s2p. Once again its what I have will get me going and can work out what sort of pack I want to build from there. They should deliver 810 amps is thory so I think good for starters. Just might not have the duration.
Will check out those remotes. Love a good DIY Project
Cheers
There are lots of builds here that use those three Flipsky items so you are choosing proven componentsđ
Make sure you buy the round shaft ver of the motor not the splined one and most choose the 120 ver.
You might want to read up on ways to cool the VESC
You may want to read up about prop choices for that motor. Lots of people use a Flite prop reamed out.
Various opinions on prop guard here. Some users have had difficulty with launching until they removed them. IMO the prop isnât the danger point itâs the foil, learn to let go of the trigger when falling and reboarding and you wonât be exposed to a powered spinning prop anyway.
Thanks for the comments.
The motor shaft I would have assumed the splined one would be better. What is the reason to go for the round shaft?
Yeah prop guard I wasnt so warried about but just thought it might be a good idea. The motor is only fairly small so would think not going to carry much energy once you let go of the trigger. I guess can always try and just take off once confortable.
The splined shaft limits your prop choices as most are designed for the round shaft.
A good training exercise for letting go of trigger is use a lanyard to attach the remote to your wrist and then repeatedly open your hand to drop the remote. Muscle memory is there for when you fall off board.
I also flip the Vx3 around while boarding as this eliminates accidentally bumping the trigger on the top of the board.
EDIT
I was thinking maybe you might not need VESC cooling. You are using a really big foil that will pop out quickly and might get unruly when going fast so your power draw peaks may be relatively small compared to a smaller foil.
