Hello.
Im new here on forum.
Im triying to finde and look for information for my electric fin build.
I need some advices and pointers.
For parts i have :
56102 910kv motor form Buy Products Online from China Wholesalers at Aliexpress.com

200A ESC Buy Products Online from China Wholesalers at Aliexpress.com

and 32700 lifepo4 6500 mAh cells 35A continuous and 55 A max rating.
I have 20 pices.
Also have 5C bms for that cells rated for 100A countunuous and 230A burst

What do you ppl think how can i setup this for my build.
Do i need reduction for my motor because it is higher kv rating.
Sould i go 5c 4P for battery pack or maby 6c 3P?

Any help and advice will be great.
Thank you

Hi and welcome :slight_smile:
How fast do you want to go?
Do you have an ESC already?

thank you :slight_smile:
Hmmm, As fast as posible :smiley:
I dont know how much speed i can pull from my setup (parts)…
Yes i have ESC alredy, why?
My motor is 910Kv so i will need to use some kinde of gearing or really small prop with 5/6 blades.

That’s 160A at full throttle and the guy blew up his 400A esc, on 6s!!!
He used a 700kv motor with 94mm prop
So for your case I would try 6s 70mm racing prop

Do you think 10:1 gearing will help with load on motor?
I was planing to use gearhead to get more torque on output shaft
