While watching lecture at Coursera, i tumbled over this fourmula
Moment
[tex]\mathbf{M}=\sum_{i=1}^{4}(\mathbf{F}_i\times \mathbf{r}_i+\mathbf{M}_i)[/tex]
where F is uplift force from a propeller, and M is drag moment for a propeller.
But why they add drag moment(torque) like that? Maybe it will differ for central point.
