Put the 46 in it. I have a Magic with a TT 36 pro in it and it was't enough power to pull out of a torque roll fast enough. Also I think a lot of people on the internet lie about the weight of their planes.I used mini servos and built it as light as I could and mine weighed 4 pounds 2 oz weighed on baby scales that I check with a 5 pound dumbell weight every time I weigh anything.
