How to figure out what it will be

[Bushwacker]

Hey guys,

So can you guys help educate me on how to figure out what my setup will produce mathematically? Never bothered to learn how to do it and now I want to.

Motor: DM 4330-216Kv
ESC: Mezon 90
Battery: 2 X 3700mAh 22.2V 45C
Prop: 20x8

Example to figure out RPM, aren't you suppose to multiply volts by Kv? So in this case 44.4x216=9590.4 anyway I would like to figure out all I can mathematically.

Thanks much.

This may help! Check it out and let me know if you need anything more. I believe their is another calc that has been used for quite a while as well that I can find if you need it.

Here's the other one that's free http://brantuas.com/ezcalc/dma1.asp

Volts x kv = rpm. Buy to get the good details as far amperage or watt ratings of a system I hot no idea other then the programs above lol

I find this one from [MENTION=95]Aeroplayin[/MENTION] to be solid. He knows this stuff!

[MENTION=3218]Suds[/MENTION] thanks man I like this one to. Heres what I got.

First setup is on 19x10 Prop. Second set is 20x8. Pretty sure I set all parameters right. Might be a bit light on weight though.
