The manual may look scary but once you get your head around it they're fine to setup. I've ran one in my elefant and have found the ESC to be a fairly large weakness. The chips which control the elevation and traverse burn out very easily, the ESC current limit means that my elefant couldn't turn on grass despite 3:1 drop outs and speed 400 motors. There were also issues with one side powering up before the other, you could balance this with thé trims going forward but then you wouldn't run straight in reverse. Aside from this the sound on the slu is excellent and all the light functions etc work very nicely.
