I don't know how many watts the motor is-I got it with a bunch of rc stuff at an estate sale and it has no marking on it. Yes-60 amp is a bit much but it was all that I had.
The prop is a 10x6. The motor mount is available at Tower Hobbies- made by Great Planes for medium-sized electric motors but they also make them for small and large motors. It is super light weight aluminum and has a ton of adjustments. One of the best motor mounts out there!
