I´m trying to build a "KISS" mid size copter ("Keep It Supper Simple" philosophy), easy to transport, cheap, gimbal capable and ... nice. AUW about 1.2 Kg (w/o gimbal), flight time about 25 min with 5000mA, 4S
Below some images of my new proposal, recovering all learnings from previous designs:
QUAD frame, 610 mm motor-to-motor
AQ 6 board, DIMU 1.1 & QUATOS
Retractable legs using RcTimer 15090 retractable motor system (as in my HEXA)
ESC: KISS 18Amps from flyduino mounted beside motor brackets
MOTOR: RcTimer HP4215, 420kv
Propellers: TMotor, wood (new product) 14x6
Available heigth for gymbal: 177mm
All brackets 3DPrinted in ABS - Carbon Fiber material
Hope you like
