Kjell Olav I recently finished an electric Genesis. I previously have flown with a YS170 powered Genesis. On the electric I started with the same thrust alignment. It worked out quite well. I have afterwards added a bit extra of right thrust. On the YS genesis I however have a bit of throttle to rudder mix so it’s hard to say if there really was any difference.
My conclusion is that using the identical angles is a good start. If your side thrust will be too little, and difficult to change, it can always be fixed with a throttle to rudder mix.
Since your vertical CG will be different on the electric it would be fair to assume that also down thrust may be affected, but on my models I found no difference.
