Dan, thinking about your dilemma, my build slowed at times due to the need for a helper. You are right reaching out and trying to establish a person or two to assist because there are several assemblies during the build that are impossible, or at least very challenging to do alone...bottom wing skins, fuel tanks, leading edges and several areas in the fuselage kit / tail cone come to mind. When you find yourself waiting for help, also move a few chapters ahead and continue prep work on the parts...there is always something that can be completed.
Wings, empennage, fuselage and finish very, very slow builds completed. Avionics and engine installed.
Down to last 90%.
