After the Corona months it is finally going on.
I received the batteries lipo 13S 40Ah, everything looks very good.
I did the first two test drives. This caused the following problems: When starting, I had too little power, so I decided to set the Vesc 75/300 from Motor current 120A to 150A and the Battery current max from 150A to 180A. Attached pictures. The second start was better, but it was difficult to foil. I started foiling at full throttle and max. 2350rpm. I don’t think the motor can turn more than 3000 rpm .That is not enough!
How many rpm makes the FR motor when you drive 30kmh? what is max?
Where can I change something?
By the way, the passive water cooling works perfectly. The Maytech tells me temperatures around 22 degrees with about 10 degrees water temperature.

My built with all specification is this:
> **[The German Fehmarn Build](https://foil.zone/t/the-german-fehmarn-build/6546/19)**

> silicone conformal coating can break. I want to fill it up with corrosionX, than heatshrink over it . Inside the heatshrink some normal silicon. I hope, the signal is enough for 1 meter.

What remote are you using? How is it set up? Battery and motor current are both very high so you should have plenty of power! Do you have a BMS? If so, does it allow enough amps to come out of your battery?

You need to check real-time log in vesc tool to see you have 100% duty on full throttle on your remote
Ppm duty test before current control ( easier to see if there is a problem)
Out of the box , wizard motor +remote ( foc, duty mode) … +35km/h with motor 120A and battery 90A with a 12s 24A
Something is cutting 1/2 of your rpm ( remote settings battery bms …)

Maytech v2, and setup? switched on… 🤫
My BMS is 120 continuous and 180max! very powerfull.

is it the normal way to press the remote 100% for starting?
The try yesterday doesn`t worked, because of the wind and waves. Too less power…
I just loaded the default vesc in my computer. In one point there is a big difference.
“General Wattage” in default is 1500000 Watt. In my configuration it is 7000W.
Is this wrong?

Did you run the motor and remote wizards?

No depending on setting usual 50% is enough to take off
Try to log with vesc tool max erpm ( not rpm ) in the air
Use only vesctool usb with version matching firmware at first , even with metr via phone you have not all the settings

I would run the motor wizard and do not change anything beside battery current maybe put it to 100A. It should work like that no need to play with all the settings!

Yes , cut down the power
Leave every settings default , just adjust motor and battery amp , voltage cut

Big but you can run detection directly on motor page

Okay, I will try it right now. Thanks a LOT.
BTW, it’s me on the photo After 15minutes.
I am proud…
