Sorry for my poor writing, trust me I'm trying to explain it as clearly as possible :)\r\n\r\nAfter testing several models, I decided to design my own model using Fusion 360.\r\nWing span: 80cm, weight without electronics is approximately 149 grams.\r\nThis plane is not suitable for beginners with RC planes; the speed is medium to fast. Wing profile uses a semi-symmetrical MH30.\r\nTo print the fuselage, there's no special requirement, except for the front part, which needs some thickness for the motor mount. All fuse parts are 1 perimeter (0.4mm) and have no infill; some have top/bottom layers to ease gluing and add some rigidity.\r\nTo print the wing, you need attention: 1 perimeter and 1.5% infill for managing airfoil curvature. Add top and bottom layers to ease gluing and create a solid joint.\r\nThe wing part is just one side, so you'll need to copy and mirror it to make the other side.\r\nCG (center of gravity) locates at the front wall of the spar canal; the wing mounts to the fuselage with 4mm screws.\r\nFor gluing, I use UHU All Plastics glue, which works very well for thin 3D print parts.\r\n\r\nI created two front (nose) models: a short nose and a long nose. The long nose will benefit managing the center of gravity.\r\n\r\nSettings for the plane:\r\nAileron up: ±5mm, down: ±5mm;\r\nElevator up: ±3mm, down: 2mm;\r\nYou'll need to set end points to achieve this.\r\nAdd an exponent of at least 30% or more.\r\n\r\nMy electronic setup:\r\nBrushless motor: 2204 CCW 2300KV;\r\nTGS propeller: 4.75 x 4.75;\r\nESC: 20A;\r\nLipo battery: 850mAh 3S;\r\nServo: 9g;\r\nOf course, you can use your own setup.\r\n\r\n
