Now I will build this giant Cessna Citation CJ1 RC plane. I will use 6mm foam board or Depron foam for the material and will test it with pusher prop configuration and also ducted fan (EDF) for more scale look, and also will try 3d printed retract landing gear for the first time.
The reason why I design the plans and build the RC plane is because of an event a "Homemade scale RC plane festival" that will be held on 20th January 2024. I don't have any big plane anymore my last big model C-130 was already sold. The announcement was on the middle of December, so I still have about a month to design the plans and build it. Like usual I use Blender to make the 3D model and then unfold each parts with Pepakura Designer into 2D plans. I use 6mm Depron foam or foam board or polyfoam for the main material, to assembly all the parts I use hot glue gun.
