Hi Merv
I think we might have our lines crossed slightly - because I have no issue with the canopy length and shape. It's the interior where I think the kit falls down because, according to the references I consulted, the rear cockpit was modified beween the trainer and nightfighter versions, with the seat moved forward and a fuel tank inserted behind it. The kit doesn't include any dual controls for the trainer and, with the seat in the nightfighter configuration, there's no room for them. If you compare photos of the full-sized aircraft, you can spot the different seating positions of the instructor and the radar operator.
I agree that the kit is excellent for a nightfighter - and, with my remarks like "it's the best Me 262 nightfighter release to date" I hope that came across in my review. But you can't just add new decals and call it a trainer...
All the best
Rowan
