Dummy Radial 9 Cylinder Engine for H9 P47 Razorback

thingiverse

THIS IS NOT A SIMPLE PRINT JOB!!!! you have been warned ;-)H9 P47 Razorback Radial Engine. Printed with 50% infill, which I hope is accurate. PETG was the chosen material due to its flexibility and temperature resistance for the DLE 20 Engine behind. If you're using electric, feel free to select a different option.The Pushrod tubes are made from aluminium Banzai Tree Wire, available on Ebay etc, cut to size and inserted from the center. The colour scheme remains as it was initially.I applied acrylic paint and sealed with Testors Clearcote Matt for a smooth finish.Unfortunately, I had to remove the two bottom cylinders to allow proper cooling for the DLE 20 Behind. This step is not necessary if you're using electric power.The Spark Plug Leads might not print correctly, but in my case, some of the outer ends didn't quite work out. However, this issue was easily concealed by the plane cowl.I used a dremel to carefully cut out the back for better aerodynamics, and you can do the same if desired.To accommodate the timing sensor on DLE 20 Engine, I removed a small section from the top of the main hub.Once complete, I attached it to the Plane Cowl using Silicon.Be advised that this print job will take approximately 24 HOURS, and in my case, it took three attempts due to different printing issues each time. Good luck!
