The propeller is cheap aluminum from the store
I reduced it to 14 cm
This did not really work and reached only 14 kph
I am currently using a 18 cm propeller and reaches 29 kph
I’ll try a propeller with Pitch 6 and if that does not work then I’ll try to print a propeller (I do not have a printer right now)
Thank you. Which site please ?

Dies the cells get hot in this configuration ?
And if i may ask you : 390kv with 5:1 it is pretty low with 18650 , the voltage drops to 3.7v fast on load , you said 29km/h , do you know the pitch of this propeller?
With my 30A battery I ride one full hour , 15.8 km .
The battery get little bit warm after one hour of continues ride on 3/4 gas (most of the heat is generated from the bsm, I got bsm on discharge).
The peach on the prop is five.
It’s the exact prop like Silvio has (thin build 45 mm)
But I feel like my engine still got plenty of power and I’m planning on 6 peach prop with the same diameter or even higher peach with lower diameter.
Only 273 kcal. Very low consumption 
In load the battery works at 49 \ 52V
Which is fast enough with 390 kV and 1: 5
12s 18650 stays at 49v?
14s 58.8v at fell charg .
the bsm turns off the battery at 43.9v .
My charger is 10A
(There are more powerful, not recommended)
I do not understand much about electronics.
I was advised by people who build batteries,
This is the best way for the purpose of results
durability (Hope for at least two years of use)
stable battery = safety
Ok thank you , 51.8v (3,7x14) , that is what i was planning for my built , 18650 has lower load number then lipo …
more info about battery please …price …shop…etc
thanks
Router bit bent and spinned itself off? What kind of a bit is that? Look like fork <:P
Flat Boring Bit\Spade Bit , it was short so I welded him another one,
but that was’t the problem . i inserted the drill only 5 mm into the router
because it was short and after welding instead of putting it all the way
i just lowered the height limit of the router ,i was in a hurry and that was stupid . in the end I ripped off styrofoam studs with my fingers
14s 30a
51.8v nominal (58.8 and fully charged)
cells Samsung 25R (8C)
bms 150a from AliExpress ,I will ask for a link from the person who bought the bms for me
Pure nickel, lead conductors soldered to a custom busbar made of copper
And I’m going to wrap the battery in fiberglass cloth + epoxy and waterproof connectors
He held up 10 hours of work even though he was not supposed to work in more than a few seconds.
