I had the same problem with mine. I had to purchase another one from Lanier and this time I used 3/16 ply and 3 bolts per side to attach the canopy. I also used some sylicone under the canopy plastic and used small screws to attach it to the frame so no air could get under the plastic. If you use a pilot figure, make sure you put some 1/32 or 1/16 inch ply under the pilot area.
