More careful shaping of the canopy frame to the fusleage. I found it useful to clamp the frame to the blocks I have secured to the fuselage, otherwise the sides sit in a bit towards the rear and the arc it forms is therefore higher. Also, by clamping the canopy to the blocks, you ensure it sits where it will sit when finished and this is the position on the fuselage that you need to shape to. It is quite a tricky job - a little at a time is best. The manual says that the bottom flange of the frame must not be less than 1/4" to allow the skins to be bonded to it. It is less than a half inch in some places now so I am proceeding carefully.
