Pretty happy with efficiency with the 950cm and 3blades 6inch. Will be interesting to see the gain with folding prop and a 1100 or 1200cm2.
I had a weird over current fault not even pushing it. Haven’t had one for ages

1250 high aspect proto and folding prop. If I carefully maintain 23-25kmh I get 37-41Wh/km pretty efficient. Giving little pump it drop to 9amp
The tide was helping a bit

that’s awesome. well done!!! can’t wait to ride mine
Impressed with the folding prop and this 950 front wing. Start to feel pretty fast.
Got a weird Over temp FET fault while temp reading were cold. Can’t explain it.

Anyone replaced the Maytech trigger spring with a harder one. On high speed crash even if I remove the finger of the trigger just the impact with water give the board some trottle. I had quite a few close call lately.
The trigger spring on the Lift remote is much harder.
why don’t you add something like this? Foil Drive Assist, DIY - #88 by pablo_foil It’s just a reed switch that powers off the rx. Haven’t tested it on the water though, if i find the delay too long i might add an arduino between the rx and esc, so that if the reed switch is released, the brake is activated instead of cutting the signal
Remove it and counterwind it, it does help at least for a while. I do the opposite to have less finger fatigue when riding longer time.
Never thought about the case of accental gas, you are probably right.
I guess it only happen when going fast, above 40kmh
Interesting, where is the switch located?
In my opinion, the trigger on the remote control should have a trigger guard, like a pistol. This will prevent hitting the trigger when falling and will prevent accidental pressing during reflexive squeezing of the hand (in the case when the finger is outside the zone of the trigger guard).
not my finger pressing it, the impact on water does
Triggergard will perfectly protect against water impact.

It’s inside the waterproof box, the magnet activates the reed switch from up to 1cm.
I also added two magnets inside the box, next to the reed switch, to keep the outer magnet “key” in place. I really like it as a key, since you can see if it is “armed” by just looking at the board.
On the downside, a small wave would take it out of place, so it only works with larger boards (unless you shape the key as a cone or something similar, i think someone in the forum did something like this)
As for using an arduino, it’s easy to read the signal from the rx and the arduino nano takes almost no space. Then you can program it to send the ESC whatever signal you want when the reed switch is open. But then you’d be adding one more point of failure.
If you’re using a cheap pwm rx as i am, you can reuse part of this code: GitHub - jfitter/12PWMtoPPM328: John's 12 channel PWM to PPM/Serial converter for R/C use. . I tested it a while ago for an rc project and it worked fine reading the rx input.
I worked on my ejection technic today… Did anyone run the FR/Lift motor at 16S? I’m pretty keen to have a go…

Will try 16S soon on the FR motor, Dale offered to use his battery for science…
On another subject, anyone fitted or tested footstraps on efoil, wondering how ankles cope with crashes?
Based on how ankles cope with wakeboards which have huge support and are light, I’m going to say a big fall with straps will hurt 
I do think a front strap would be handy sometimes though!
Collegue of mine broke his foot with kitefoil+straps. Board stopped and he continued😀
Should be the same with an efoil, i wouldn’t use straps.
I added straps to my board recently, and I will never take them off again. The gain in control is massive! They must be tight so, just my toes are visible on the other side. Many crashes with them, but crashing is basically the same as without straps.

I just tried my efoil in 1-2ft waves, i don’t surf normally so this was challenging for me. What do you do if you’re stuck in the straps when falling from a wave or get a wave that hits you?
I bet they provide more control it’s like kitefoiling strapped or strapless. What I’m afraid is the crash at high speed where you nose dive. They are by far the worst… you manage to eject before hitting the water on these?
