Functional parameters are measured on ground with clear texture and sufficient lighting. Ranging accuracy is 1% repeatability and 3% absolute accuracy (absolute accuracy degrades with distance and may exceed 3% in some cases, while repeatability stays very stable — drone altitude-hold stability depends mainly on repeatability).

Night Operation and Vibration Isolation (all models)

Damper (short 4×3 cm / long 10×3.6 cm)

A damper mounting plate is included as standard to absorb airframe vibration. During hover tuning the VIBE factor should stay below 30; keeping it under 3 gives noticeably better altitude and position hold. If vibration is too high, improve the isolation or change the airframe.

Night Fill-Light Board (optional)

36×20×4.7 mm, 15 W total, 10–30 V supply (mind the polarity — reversed polarity destroys the board), 6–8 m range at night. Mount the heatsink before powering on, and place it under the propellers to speed up cooling.

Infrared and visible light produce different imaging textures (sensitive to material and distance, not to colour), so it is normal that the human eye cannot see that texture. Common surfaces such as concrete, marble, lawns and asphalt all work normally.
