This is a little tricky but not difficult. Use two pieces of 1/16 or 3/32 plywood as the core of the attenna seperate them enough for your rx antenna to pass through. Add a short length of 2-56 threaded rod to the plywood core to attach the scale antenna to the fuse. Add balsa to the side of the plywood cores and shape accordingly. A 2-56 blind nut in a small 1/8 plywood plate is attached to the top of the fuse flush with the sheeting. You can then run your rx antenna through it and carefully assemble it to the fuse. Add a drop a ca or sand the bottom of the scale antenna it until it tightens and is straight with the fuse.
