Never built the Hasegawa kit but have done 4 of the Eduard kits. As mentioned above about the issue with the clear part fit the fix is very easy. The cockpit size comment may be related but it's more the shape of the fuselage halves. A light sanding of bulkhead at the back of the cockpit, inside the arrows below is needed mostly for a good clean gluing surface. Scrape the paint off the inside of the fuselage for good gluing surface as well and clamp it at the arrows Glass fits perfect. I think the cockpit fit is less of the issue. I had to do the same clamping with a resin cockpit replacement and the glass fit perfect that time too.
The wing trailing edges are thick but fixable by sanding the flat glue surface on the inside. Careful to keep them parallel so there's no gap. Main LG struts need to be cut about 1/8 shorter to give the plane a more nose up stance on the ground.
I nice feature is the preformed nose weight. Not sure if that come in he weekend version but its in the dual combo and the profipack.
And FYI to help prevent the "detail oriented" guys off your back The pilot usually entered from the right side since it was a pain in the rear to climb over the throttle quadrant. So if you do an open door it's usually the right. It was amazing how that ...hmm.. "discussion" got out of hand so fast
