Senseless Brushless 2650KV Motor running on 7.4v for 5-6 mins
racing consumption need to be around 35A (3300mah battery)

0.0225 ohms coil resistance not relevant when running.
18Vmax will be running at 7.4v
1.4A off load current
52A max current

I am looking for a start point, I was hoping a 35mm 1.4 would be ok ?

Thanks .

Would like suggestions of propeller size diameter / pitch.

Hi
A 2 blade 32mm x 1.4 pitch would be closer to the mark.
That's what my Hobbyking outboard has with a 3000kv motor, but, it's now running on 3S 2650mah.

Thanks Cannabis, for the information I have noticed that brushless motors seem to run better on smaller propellers. than brushed direct drive.
