Quad - How to calculate motor size requirements?

jcnh · 07-20-2012, 10:49 AM

Hi folks,
I know that this has probably been covered before but I can't seem to find the info. I wanted to add a camera and gimble to my F450 quad but I was not sure how to calculate the weight limit of the existing equipment that I have. I'm running the 30A OPTO ESC's and DJI 2212/920KV that came with the Flamewheel F450 kit.

Likewise, if I figure out what my total weight will be with the camera and gimble, how do I calculate what I would need for motors and props.
Any assistance would be appreciated.
Thanks,
JC
