RE: Hl yak 55
I dont know about scotch tape..... That seems to be a little to weak for my liking. I would suggest picking up some duck tape brand packing tape at Wal-Mart. It seems to work really well and I have been using it on most of my foamies. I would also suggest that if you are going to use tape, make sure and hinge both sides of the wing. Just move the ailerons, rudder, and elevator to full deflection and then put the tape on. Once this is done move the part to full deflection the other way and then hinge it also. This is a trick that I learned from putting together an Ikaraus Edge 540 shocky.
See ya
