@4knflyin If you followed Top Studio's instruction to cut the front bulkhead, then remove 1 mm or so of material from either cut end. The replacement Top Studio plate pushes the nose forward making fitting the nose to the cowling, the most important joint in the model, impossible. I also had to shave the interior of the nose to seat properly. Thankfully the underside of the nose is black and can be easily brush painted. Best of luck. If you have question, I'll do my best to respond!
