1:75 Boeing 747SP – Update #19

There has been good progress since my last post, but is has been very time consuming. The detailing of the fuselage with logos and windows using 3D printed stencils and an airbrush has provided some challenges and valuable learning’s for the next model I build, but overall I’m fairly happy with the end result. The key to using stencils is applying light coats and allowing time to dry a little before each coat. This prevents bleeding under the stencil. On the flip-side, it can can also result in slight ghosting around the edges if the stencil is not in complete contact with the surface, so having the paint thinned down to the right consistency will also help. A cotton cue tip with a little window cleaner helps tidy up around the edges where required.

In the avionics department, fitting of the circuit board and connecting the engines has been challenging but rewarding. With limited space inside each engine nacelle, its been rather painstaking connecting the wiring, testing to make sure both the motor and LED work in each nacelle, then carefully packing the wiring into the nacelle without breaking any connections.  After testing, all 4 motors with LEDs were running, but after replacing the temporary connections to the circuit board with permanent ones, at the time of writing, I had 4 motors and 3 LED’s working…so I’m still troubleshooting to fix that 4th LED…it might be call to my avionics buddy for some advice…
