I think this is the most detailed model among the Revell-Germany’s Easykits and is very suitable to be customized. This model is very large, it is 435 mm long. You need to use glue or model can come apart.
I put a electronic circuit into the model for flickering engine leds with control trimmer. In the cockpit i have used fibers optic and auto-flashing leds. The auto-flashing leds are inexpensive and do not require electronic circuits, I used only the resistors for power supply to 12v. To enter the cockpit with the lights I had to cut some “internal bulkheads” of the fuselage and bend the optical fiber with hot air from a hair dryer.
During the difficult closure of the fuselage (with glue) I think that some of the wires of the circuit are disconnected because now work only three of five LEDs. Missing a yellow and a green. Maybe this is better because otherwise the cockpit looked like a Christmas tree.
