FlySpark M18ZD1 Single-Channel Drone Smoke Canister Dropper | M18-Class Canister, 48×48×88mm, 5V, PWM / Light-Sensor Trigger, DJI Air & Mavic & Quick-Release Versions

FlySpark M18ZD1 Single-Channel Drone Smoke Canister Dropper is a compact drone payload release unit that carries one M18-class smoke canister under a small multirotor and releases it on command. The dropper body measures just 48 × 48 × 88mm, runs on 5V and weighs approx. 77g in the LED version including its strap, so it fits under DJI Air and Mavic camera drones as well as FPV-class and custom-built aircraft.

The M18ZD1 is part of the FlySpark UAV Payload Droppers & Release Systems range, supplied and supported in India by AnuShakti Infotech Pvt. Ltd., with export enquiries welcome. It is offered in three versions: M18ZD1-LED-V1 with a light-sensor trigger for DJI Air 2 / Air 3 and Mavic 2 / 3 / 4, M18ZD1-PWM-V1 for PWM-signal aircraft, and M18ZD1-SQ-V1 with a quick-release mount.

A curved cradle conforms to the canister body and a side-mounted servo latch holds it securely in flight. A foam saddle on top seats firmly against the aircraft belly, and the unit is fixed with a strap or zip-ties, with no drilling or permanent modification to the drone.

WHY CHOOSE THE M18ZD1 DRONE SMOKE DROPPER

Smoke is still the fastest way to show a ground team, boat crew or helicopter pilot exactly where to go and which way the wind is blowing. The M18ZD1 lets a small drone place that marker precisely, from a safe stand-off, in seconds. Because the LED version is triggered by the drone’s own auxiliary light, it can be fitted to a standard DJI Air or Mavic in minutes without opening the aircraft or adding any wiring.

For FPV-class and custom-built aircraft, the PWM version connects to a spare servo output so the release can be mapped to any transmitter switch, and the SQ version adds a quick-release mount so a crew can swap or reload droppers quickly between sorties.

HOW THE M18ZD1 DROPPER WORKS

The M18ZD1 holds the canister in its curved cradle with a single servo-driven latch. When the release command arrives, the latch opens and the canister falls clear in one action.

• • LED-V1: the optical sensor is taped over the drone’s bottom auxiliary light; switching the light on from the flight app triggers the release
• • PWM-V1: a 5V PWM servo signal from the flight controller or receiver drives the latch
• • SQ-V1: the same PWM release, with the dropper fitted on a quick-release mount

COMPATIBLE AIRCRAFT & MOUNTING

The LED version is listed for DJI Air 2 / Air 3 and DJI Mavic 2 / 3 / 4 folding camera drones and needs no electrical connection to the aircraft. The PWM and SQ versions suit FPV-class quadcopters and custom-built multirotors with a free PWM output. Always confirm that the aircraft’s take-off weight and balance remain within limits with the canister fitted.
