New 3905 E maxx AXI Outrunner setup

[xpy]

Hi guys,

I'm new here, I come from Germany so don't be suprised about my bad English.

I want to convert my E-Maxx to brushless. The SetUp I thougt about is this:

- Kontronik Jazz 55-10-32
- Axi 2826/12
- 8s1p FePo4

My Question:

Do you think it will work or is the motor too powerful for the ESC? I think I would gear it 40/22 for the beginning and if the ESC is not getting too warm I will go up to 40/25.
Will the motor get along with the 8s FePo or is this too much for him?
What do you think about the runtime?

Hi Xpy,

I think the motor and the ESC are made for each other. Be sure to put the cooling fan on the motor though. It does make alot of difference in motor temps.

8S FePo? I have ran 6S Lipo on the 2826/10 motor with 22/40 gearing. 8S might just be ok with the 2826/12. Run it for a little bit, then check your temps to make sure they are cool enough for your liking.

Runtime? What is the Mah capacity of your battery setup?

Well, FePO4 is short for LiFePO4, that means his batteries are 2300mah, because LiFePO4 is A123, IIRC.

Of course i would put a cooling fan on the motor.
I think the runtime should be at about 18 min. Do you think this could be possible?
