Bombardier CL-415MP RC plane is finally finished, it's weight about 2200 grams or 4.8 pounds, but it can take off smoothly without using flaps. Also the landing can be done smoothly, with some adjustment. The front landing gear needs to be glued or bolt up to the fuselage. It's often came out of its slot and causing a bad landing. The aileron also needs bigger area to give sufficient control, I already revise the aileron size. The plane is a good flyer if you familiar with rudder control on turning. The hardest build on part 4 is building the wing tip floats, you need to watch the build video tutorial on youtube as well as build instructions with images in Paper Replika website. You can use differential thrust control or common control to fly the plane. The next build will be PT-17 Stearman.
