I'm sorry for the slow update, as I had a snag working on the main landing gear bay and I had to pause to think about a workaround (I might be able to use triangular plates like I did in SR2, which would take a long time) and I'm in eighth grade now and don't have a lot of time to make the plane.This update makes the structure of the main landing gear[Very hastily made, the landing gear also needs to be adjusted to withstand the impact of the landing, which will be completed in a week], refines the nose landing gear, adjusts the counterweight and wings, and the landing gear on the left side is not retracted correctly now, I will improve it later [I will try some methods to make the landing gear door in the future, or make the engine first, depending on your reply]
