Leon, have you considered the completely crazy idea of devising a simple mechanism to tilt the motor axis towards the CoG in order to lower the yawing moment in case of one motor failure? The decrement in moment arm in respect to airflow efficiency if the nacelle holds an angle x with respect to the CoG, and you tilt the motor an angle y, the ratio would be: [ sin (x-y) - sin(x)] / [cos y - 1] In case you prefer the LaTeX equation: \frac{\Delta M}{\Delta \Phi} = \frac{\sin (\alpha - \theta) - \sin (\alpha)}{\cos(\theta) - 1}
Another informative video .I have one doubt at 9:46 I can see you using the Parasite Drag tool ( OpenVSP). I also tried getting the drag value this way but the drag percentage due to fuselage and pretty much anything except the wings is coming out to be zero. I know you said in this video that you are not fully acquainted with the software but have you ever had to face this kind of problem while using the software. I am find using this software quite a bit challenging any help regarding the above problem will be helpful. Thanks for the video!!!!

I have not revisited the drag issue in a long time so I can't provide any additional guidance. When I do get back to it I'll make another video.
you cant just say "we discussed q in another video"
