Hi!

I am relatively new to RC and have been working on a twin-prop electric RC plane. When it comes to wing leading edge mounted engines, I was wondering if there's a way to determine how far out the propellers need to be from the leading edge, and what angle they should be mounted at with respect to the free stream or the wing chord line. Is there some calculation or simulation I need to run to figure those numbers out? How can I do this?

Any insights would be very appreciated.
Thanks!
