Here's an overview of the power set-up for you. Note the practicality of using stubs at each corner when it comes to storage, handling and maintenance and beside this I've taken the opportunity to install bridge handles for general manoeuvring, which attach to the flight-deck with four M8 bolts.
Working with the airframe is a lot simpler with safety grilles removed, as you can step inside its perimeter to pick it up. Going forward these will be units dropped into place when preparations are complete, though for the purposes of test-flying the semi-grille shown will do. Though perforated their material is actually quite weighty, but there are perforated plastic sheets available which may improve on the aluminium.
