Fuselage plug is actually made in 3 pieces, a front cockpit plug, a main fuselage plug from the intake rearward and a separate nose cone..... the front cockpit plug slides into the intake area of the main fuselage plug forming a tight joint. I have done it like this as when this model is finished I will be able to go back and make another front cockpit.plug for the 2 seater version as that too will just slide into the intake joint.
