The electronic projector of Tarot's drone factory is made high-quality Material processed and assembled by CNC. The structure adopts the design principle of mechanical lever, which can reduce the output power required by the driving mechanism, making the projector compact in size and the hinge structure of the lever components not get stuck due to the weight of the load (the maximum measured load is 43KG, and the load is smoothly retracted) Multiple electronic throwers of this series can be mounted according to the usage environment, and the order of each thrower can be independently controlled. Colour:Black Material:Metal Product operation instructions and LED status light description: Note: This product uses standard PWM remote control servo signal analysis (the following description assumes a 0-100% stroke amount based on the analysis results) 1: When the PWM signal input value remains between 0-59% of the stroke, the LED red light remains on/the device does not act; 2: When the PWM signal input value reaches 60-100% travel, the LED green light flash once/the device release switch be turned on once; After the placement is completed, the LED light remains green and always on 3: When the device does not detect PWM signal input, the LED red light flashes (2 times/second); 4: During power on initialization, if the detected PWM signal input value is within 60-100% travel, the LED green light flash (2 times/second) until the PWM signal input value is adjusted to 0-59% travel, triggering the first operation. Package Contents: 1 * Accessory 1 * Washer 4 * Screws Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
