Got the reception fixed. External and internal antenna are about 2 - 3 mm apart. The controller keeps connection even under water and up to about 5 cm distance. Above the water surface the reception is perfect up to a few meters away while the foil assist is under water.
Here some images of the updated reception plate. It now also holds the nuts in place and stays on the board.
Today I tried the small 35L board again with the improved antenna. But I had no luck. I will need to use a bigger board, at least for the beginning. I got once into foiling while lying on the board but I could not repeat that with standing up. The board just sunk or I stalled it.
Next try will be with the downwind board which should be a success. I also ordered the blue Foil Drive 3 blade prop, which will take a while to arrive.
Also the motor can not reach more than 100 phase amps. Probably it is due to the battery or me limiting it to 45A. Maybe it can take 50A for short times. I think I will build a second 1P with those RS50s and see how that goes.
What is your foil? I would suggest starting with a big pump foil.
Today one of my friend with lots of efoil experiance tested the V2 assist I lended him, and reported he had trouble to start also, keep in mind motor is very close to the board and will ventilate easily, it puts a lot of movement/force to compensate.
so first, try to keep the board level with the water, push on front feet to avoid liftoff. WHen you have more speed than you think you need, then you can lift off, either directly transituion to pump, or transition to semi-submerged prop but then you need to reduce throttle significantly. you can see here I need to work the board a lot when prop gets in and out of water, and this prop is the high pitch volker based prop, handles semi submerged mode well.
I used the the Veloce H XXL with 1300 cm^2. You are right with the small board I should try a bigger foil at the beginning or bigger board. I have also the Trail XL with 1940 cm^2 and very thick profile to try.
I am sure it will work with that small board one day. Just need to build up the skill. While on the belly it worked out really well keeping the board level. When transitioning to my knees and standing up that’s where I mess it up.
Don’t stand until the board is on the plane. This is where everyone loses momentum and then starts fighting the board and motor. Ideally you want to be at around 13-15 kph and then stand up.
