Thanks Saucisse, AJ and Edgee400. I'll use the double-sided tape, packing tape and glue combo.
I'm still trying to figure out how the aileron servo cables run. I know how they go in the spar channel, connect to the Y-harness.... then what? there appears to be some kind of hole in the fuse where the two wing halves meet but that hole does not lead to the fuse where the RX will be. I know there's something about this somewhere in this thread (read through close to every posts here). Do I need to dig out a hole? Grateful for some help or pix here. The instruction leaflet is of little help, unfortunately.
