Your guidance please, gentlemen...

My Jelly Bean has a Vision 400 motor running on a 9.6v 3500a/h battery pack...so what do you reckon for the prop  size (which is in a 40mm id steering nozzle) ....35mm two blade plastic ( standard type, not an X type) or a 35mm three blade plastic one?

Two blade plastic. More pitch for dynamic diving thrust..

[U-33]

Thanks chap...two blade  'twill be.

[unbuiltnautilus]

Although........!


I cannot remember if the Vision 400 is a whizzy 400, or a 385 or 360 type, pretending to be something else. If it is a whizzy three pole one, I would change my advice to a 3 blade shallow pitch type. If a slower, 5 pole type, stick to the two blade type.

Aah...now, according to my research, the Vision 400 is a 385 variant,  quite happy to have 12volts shoved up it's five poles, and possessing loads of torque.


We shall see, oh wise one.  😶


And...is that yourself I see indulging in the delights of Facebook?

[unbuiltnautilus]

Shove that 12v where the sun don't shine
...I have indeed decided to dip my toe into the joys, tears, bigotry and untruths that are Facebook, long may it continue, I feel so at home

Mind your feet then, chap...I'll see you on the dark side.
