How to determine the required twist in the Bell Shaped Lift Distribution (BSLD)
I'm doing a research about flying wings and BSLD and I'm having trouble to find the required twist. I'm using the equation L = ( 1 – x^2 )^3/2 to find the local load (Bowers, 2016). But how can I ...

For a small flying wing, can two motors with different speeds replace the ailerons?
I was thinking about a way to get rid of the aileron, and I was wondering if:
I install two motors on the wing, and make the right one spin faster than the left one, will my wing roll to the left ?
