These are great props I used them for my tricopter but do NOT use them with the power the world 2812 motors on a 3 cell they burn out every third flight (Posted on 11/3/2014)
Just bought my first hex and being a newbie, know these would be useful. At this price, I can afford to break a few props. My first order from Value Hobby(recommended by the friend who built the hex for me), well pleased. Order shipped out of Atlanta and arrived within a week. Very well pleased!
These props look like they should cost much more, if you're going to order, might as well make it worth your while. Long shelf life:-), they'll keep 'till you need 'em. (Posted on 10/12/2014)
