Mini Tricopter: Another Tail and Battery-Cover

thingiverse

Because I had only M3 30mm available and my servo wouldn't fit, I designed a brand new Tail from scratch using OpenSCAD. The motor-mount is specifically made for 1806 or 2204 motors, requiring only two screws to secure it in place. The motor can be turned to point the cables towards the body by utilizing the other holes provided. The tail works seamlessly with a Towerpro SG90 (analog or digital) servo, which is one of the lightest and most affordable options available. Additionally, you can also use SG92R, MG90S, or MG90D servos for optimal performance. The tail-arm has been designed to facilitate fast servo changes due to the high risk of damaging the tail-servo in a crash. To achieve maximum torque, I employ the middle hole on the servo-arm, eliminating the need for a full 45-degree tilt to achieve fast turns. One Clippy die is used for the pushrod, allowing for precise control. The battery-cover features slots for a Mobius or Runcam 2 camera, accommodating even the largest of batteries. A 3S-Zippy-1300mAH-40C battery will fit comfortably, including an XT60 connector positioned above it. Update: On October 21, 2017, I made significant improvements to the tail design after a crash with version one. The updated V2-arm features additional material for increased durability and stability. The servo mounts are positioned lower on the arm, providing enhanced performance. To accommodate larger props, the 6i-tail-arm was lengthened by 10mm, allowing it to work seamlessly with short front-arms as well.
