I asked a fellow flyer this question and was told to join RCU and ask this question here. I am building the Stingray 120. The manual says to attach cable wires to the top and bottom of the tail. I would think that would not be very attractive looking plus the labor involved. For the planes I have built I have always put some tri stock for the vertical fin and for the stab. Is there anyone here that has built this plane and give me your recommendation? Thank you.
