I usually stay out of these threads, but I have to say, that is the 3DHS manual. I have a 3DHS 59" Slick.
The plane in the HK guide has 3DHobbyshop stamped on the motorbox, and the person building it is wearing a 3DHS team shirt.
This is nothing but a blatant rip off. I didn't think even HK would have the stones to do something like this.
