Interior framing of aircraft

[JHF]

I'm currently building the Airfix 1/24 scale FW190A-5/6 and would like to partially scratch build the interior framing. I only intend to put on the framing on the panels around the engine, as they will be left off, and inside the rear fuselage where the radio is stored. Those of you who know the Focke Wulf 190 A series will know about the rather large hatch just aft of the cockpit on the left side. I'm going to display my aircraft with this hatch open, and thereby the interior of that part of the fuselage will be visible.

Which plastic rods are best to do the framing in 1/24 scale please?

I'm also going to insert the Airfix electric motor to turn the prop.
