does a twin engine lose its gyroscopic properties of inertia?

[raaaid]

conservation of angular momentum debunked:

you are in a bimotor with both propellers at full revolutions:

total monetum zero since they conter rotate

now you aim the right propeller to the right and the left propeller to the left

now you HAVE CREATED a huge angular momentum

science is a lie, bernuilli, friction, conservation of momentum, relativity..., the new church whose dogmas hide free energy or time travel
