first advice: don’t try to stick with hobbyking only…
They won’t have everything you need anyway, or you’ll have to compromise and/or pay more for the same thing.
their customer service is pretty bad when thing starts to go wrong…
Check for 8AWG cable on ESC, moreover if you go direct drive, with no gearbox. Chinese ESC Amperes, same goes for max discharge rate or C on batteries, should be divided by two at least! 80A is a good max value for a geared rig, not sure if a jet or direct drive could do the same performance… Better stay safe and by big ESS spending money one time only!
Thks a lot.
I have to work hard to fix somethings and to definite the right amperaggio for ride the waves (not for 6/8 minutes)
I need a lot of test and it will be interesting to know new things day by day.
Thks to VeFoil to show me in 10 parts on Youtube how to start and other guys!
I ll reply soon
ESC with/without BEC: I don’t understand 5v or more. Why I have to definite this volt?
What do you prefer about Esc; within o without BEC? Can you tell me because?
I read that some had have some trouble with esc…burned inside the tank…maybe to hi the temperature…no fresh air inside but I read, Esc was water cooled…to keep down the temperature.
I m thinking to separate and work with more tanks, one for esc, one for bec, one for Receiver and one for batteries…more are heavy but not so much but more safety!! So something burn, burn alone…
Anyway i have to keep low the temperature and I m thinking little different…we have to change the heart of the foil…
Usually 44V (12s = 2x 6s in series) and 20A or more (if needed, 2 or more battery group in parallel). I have 2+2 16A batteries in parallel. Bec, 5V for receiver, but there are dual voltage BEC also, HobbyKing has one, 12V and 5V good for diaphragm pump for cooling and receiver. More boxes means more sealing problems, usually esc separate from battery but, read the forum

Now I ll check 8awb @MaB…i have time today to seek more!!
develop a new form for the cooling system. This is really hard for me, but I’m trying to draw something …
The realy trouble of e-Foil is the Temperature. Everything is closed for keeping out the water…But…become hot after few minutes, like I m in my room to 4 pc for example.
Each pc produces heat for 70-80 degrees … so much … not good!
20Amp = 20000mAmp
You can go with 2x 6s (22.2V) 20000mA, i’ve one set of those and first tests were made with those, ok for 25 minutes or so.
I’ve also 4x 6s 16000mA (bargain from Hobby King) and lately I use these 4, 2 in series and then the 2 group of 2 in paralell. 45 minutes riding, approximately. I feel the motor more alive.
Depends on which battery and quality of battery you can get, Tattu are expensive but some people, Pacificmeister one of them, use 2x 22000mA Tattu with good results… Hobby King batteries are cheper but even overall perfomance might not be the same.
