Yes. More lift but didn’t measure it
What propeller is this?
Hey. I am thinking about start bilding one. How can i choose the best hydra-foil from airfoil database ? ( Fail that i can put in CNC and make base form from foam. )
Hello. Sorry but I didn’t understand well what you want! Can you tell me more!
I wish to make front and rear wing from polymeric foam. How can i do it ? Is it possible to do it with hot wire ?
I thinked that with CNC would be easyer.
I heard that i can take sketches from airfoil database.
How can I choose hydrofoil there that will work ?
Hi. Ok I see. I don’t have experiences in wings maker. I sell remote and receiver if you need it but don’t have build the wings. If I can give you a free advice, don’t build it but buy it. for exemple you will have the best wings (in my mind) in RL for about 300 euros… Sorry to don’t help you a ot.
And if you need a good remote, here I can help you

Thanks for opinion 
What wings do you recommend from RL. Do you use their mast as well.
No I use crazyfoil mast and wings but after months of reading I love the efficiency of rl. I know from last year they have a v2. Just ask theme!
I use the 2018 RL wing with 1200cm2 not the new one with 1600cm2. I‘m happy with it, it is in a good range, starts to fly at 15-18km/h, max. speed around 40km/h. I do not use their mast, as the fuselage has flexible hole spacing so it fits to most masts. I own also an RL mast, it‘s ok for the price but not anodised and not the most rigid one on the market.

Ho . So crazy to see my battery build doing by other one🙏
Hi, are you still using CrazyFoil I would like to get it, on the big front wing on what speed it starts to fly ?
Hello. Yes from 15kmh around
Not so bad, I think I’ll get one of this they are almost half of price compared with others, do you think it is possible to pump with it ? How is your built going , I’m also planning to start project with jet system already ordered some parts.
Hi. My build is finish from 2 years now. Pumping the foil is to heavy and wing too small! For efoil is ok
Are you from Canada ? I’m in Montreal waiting for part, do you still sell remotes ? and did you any experiments with jet system ?
Hi. No I’m from Switzerland waiting for summer time Yes of course. Please PM me for the remote and can kindly answer to your questions
How does the design behave after 3 years of use ? @iLouis and all the members who made this battery based on Vincent’s guide ?
