I just weighed it on my VERY inaccurate scale, it shows a tad more than 7oz. all up weight after the addition of a little extra glue here and there to because of some pilot errors . i did not weigh the motor before installing it, but it is super light compared to its size and the amount of power it puts out; it will hover at around half stick and pull out verticle with ease. this is my first 3D plane and it has really shined a new light on flying (if you want to call it that.....). This is the most fun i have ever had with and airplane, I think its even more fun than my gas heli!

ill take some pics of the motor for ya...
