View of radio box and wings
Note the wings come as 1 wing you get to cut this into two parts. The wing has lines on the part to show where to cut
Cut the holes in the boat first. I cut the wing down the middle. Then I used a beltsander to sneek up on the lines
You need the wing to stick about 1/8-1/4 into each side hole. Sand a little then try to fit, repeat until you get the fit.
Remeamber you need the wing to stick INTO the hole. Not flush with the side.
