P-47 Razorback DIY RC Plane

Print

About 2 months ago I made a poll about what the next radio control plane model on my Youtube Channel Community tab. The winner is the P-47 Thunderbolt 'Razorback' version. I made the model in Blender 3D, you can see the process of 3D modelling in this video. The reason I made 1200mm wingspan is to match my P-51 Mustang scale, both have 1/10 scale. It equipped with servoless retractable landing gear. I have a problem locking the landing gear strut, I just use CA glue so it don't have enough strength. I also made the plans for fixed landing gear. At first I use the wrong CG which is 7,7 cm, the correct CG after some trial is exactly 7 cm from leading edge of the wing root. The can fly straight with the correct CG but needs more power, I recommend to use 4S for maximum performance, but you can still fly with 3S for scale flying. I haven't fly any RC model on the last months so I was a bit clumsy in landing and take off.
