"Hi, you must follow the pictures in the wiki, yes it is correct to have those different direction up and bottom, as the motor mixing is designed to work with those directions. As for the motor heat, it is normal when the motor is designed to urn…"

"Correction, I'm using 11x4.7 on top, not 11x4.5. I just read somewhere (don't recall where)someone stating that, using bigger top props gave good results, and it does for me, it's not based on any scientific study ;-)   It…"
