Well done with the PE, I always feel all the fiddling to get the PE in the right place is well worth it, you get that little bit of extra shape and character to the build.
Working in5 the undercarriage floors. A known issue with the dragon kit so the extra bracing should fix this.
Dry test fit and adding lead in the nose and under the cockpit. I won't know till I've got the wings and tail on so I have a little wiggle room if I need to add more weight.
Nice bit of progress and sure is some heavy beefing up on the undercarriage. If you find extra weight needed, you can also add some to the engine nacelles, as long as the weight is forward of the main u/c legs.
