Thanks! I see the duct is also a very reasonable price. I think I might grab both and see how compatible they are for the 65161 motors…

hello man did you test it ? is she just placed on it FR support ?
have you a pics of the hole or the thread for the shaft ? and of course the size of the hole …an interesting design and price 
Diameter ist 142mm
for 10mm diameter shaft
Greeting Frank
Thanks for the info Frank, since its likely fiber reinforced plastic it should be fairly easy to drill to 12mm.
Have you tried it in order to assess efficiency?
I know the fliteboard foils at 50wh/km, but honestly I’m not that impressed with their prop choice for the worlds best engineered efoil in other spects. I can clearly see that this comes from their collaboration with german torqeedo from the design.

Can you measure the pitch at 70-80% diameter , please?
I ordered one and measured it out for us. It seems like a really nice option for the 65161 120kv version. The blades are quite stiff and really smooth. I really like it.

Designed similar to torqueedo but personal knowledge is that a friend of mine designed the prop and another friend designed the wing. I got to try out some prototype wings a couple days ago and they are fun to ride. Still feel uneasy having 60 pounds of board under my feet. Not as reactive as just a surf foil board. The prop and wing combination is extremely efficient. At over an hour of cruise I still had over 50% charge left.

Anything idea on pitch ? Since it a gearsetup I would think they limited the rpm on the gearbox , so probably used high pitch , 120kv or 100kv ?
I’m on 120kv and 16s so pitch is probably enough by far. Should I go for one or wait for our Slovenian friend to wake up and start delivering alu ones?
Where did you buy from and did you get it quickly?
120kv 16s 
Which Esc is used for such death ride
Using 75/300, but did blow my first 3 in a couple of months 
The 4:th unit has been good now for about 300km combined ride.
My 16s high energy battery is quite power-weak (Samsung 50E cells) and only rated for 80A cont, so I usually couple it with a 16s 5Ah lipo when I want bursts to go beyond 40kmh.
It just took 2 days (Germany)

Coupling a 16s8p(?) Li-Ion battery with a 5Ah Lipo sounds interesting. How does it work?
I was thinking more measuring it 
Many way to do that , didn’t find the one I used Last time on first FR prop but this one seems good :
Great news! Thought DeepVee was faking their inventory as they have a lot of spares in stock.
Bad part, they don’t ship to Sweden, at least not from the web shop.
Well it’s not that complicated, but it’s not a very nice solution.
So I just use 2x5S+2x3S Lipo’s in series and then connect them in parallel with the 16s8p LiION battery pack.
There is signifacantly less voltage drop under load doing this. The LiION alone drops 6v when pulling 60A. Yes after this I can not recommend using the 50E for efoils. Ive also made 14s batteries using p42A:s and there is a huge diff with “high current” batteries as these only dip ca 2v.
However if adding Lipo you need to make sure to have the exact same voltage when connecting the 2 parallel. Also you can not really use the last 10% of LiION capacity as you need to stop discharge at about 3,4v due to Lipo chemistry properties.
In light of recent Waydoo battery incidents I think I will slow down the battery experiments and also share the design I’m using for group assessment. Efoiling is really cool, but safety of family comes first.
Does anyone know that pitch of that Fliteboard prop already? Is it 150mm diameter?
