FlySpark M18SD Multi-Channel Smoke-Canister Drone Dropper | 2/4/6/8-Channel Parallel Rack for M18-Class Canisters, 5V, PWM / Light-Sensor / Remote Trigger, Quick-Release Plate & 200–900g

FlySpark M18SD Multi-Channel Smoke-Canister Dropper is a parallel-rack UAV payload release system that carries 2, 4, 6 or 8 M18-class smoke canisters under a single drone and releases them on command. Each canister sits in its own holder cup with an individual latch on a central spine, so one sortie can mark several drop zones, landing zones or rescue locations without returning to reload.

The M18SD 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 from verified end users.

All four sizes share a 200 mm width, a 160 mm height and a 5 V supply. Length grows with channel count: 67 mm for the 2-channel M18SD2 (approx. 200 g), 133 mm for the M18SD4 (approx. 490 g), 200 mm for the M18SD6 (approx. 700 g) and 267 mm for the 8-channel M18SD8 (approx. 900 g). The dropper accepts a PWM signal, a light-sensor trigger or a remote-control trigger, and mounts through a quick-release plate. The dropper-side quick-release seat is supplied as a free upgrade; the aircraft-side plate is sold separately.

WHY CHOOSE THE M18SD MULTI-CHANNEL DRONE DROPPER

Single-channel droppers limit each flight to one marker. The M18SD puts up to eight M18-class smoke canisters on one aircraft in a compact parallel rack, so a single flight can mark a series of points, signal several teams or place supplies along a route. Because every variant keeps the same 200 × 160 mm cross-section and the same 5 V trigger interface, operators can move between channel counts without retraining or rewiring, and choose the size that matches the aircraft’s payload capacity.

HOW IT WORKS

The release controller reads one trigger input and drives the latch on each holder cup. With a PWM trigger, a servo output on the flight controller or receiver commands the release. With the light-sensor trigger, an optical sensor is fixed over the aircraft’s bottom auxiliary light; switching that light from the flight app commands the release, with no connection to the aircraft’s wiring. With the remote-control trigger, a switch on the pilot’s transmitter is mapped to the release channel. FlySpark sets up and confirms the release sequence and channel mapping for the chosen trigger mode and aircraft before delivery.

COMPATIBLE AIRCRAFT & MOUNTING

The M18SD is intended for heavy-lift FPV-class drones and custom multirotors, and for DJI Matrice M350-class enterprise multirotors. The M18SD2 and M18SD4 suit most heavy-lift FPV-class frames using PWM or remote-control triggering. The M18SD6 and M18SD8 are matched to M350-class aircraft, where the light-sensor trigger over the bottom auxiliary light avoids any modification to the airframe. Mounting is through a quick-release plate: the dropper-side seat is a free upgrade and the aircraft-side plate is ordered to suit the airframe. Always check that the dropper weight plus the loaded canisters stays within the aircraft’s rated payload and centre-of-gravity limits.

FREQUENTLY ASKED QUESTIONS:

Q: What is a multi-channel drone dropper? A: A multi-channel drone dropper is a payload release system that carries several payloads on one aircraft and releases them on command, so a single sortie can place markers or supplies at more than one point. The FlySpark M18SD carries 2, 4, 6 or 8 M18-class smoke canisters in a parallel rack.

Q: What is the FlySpark M18SD? A: The FlySpark M18SD is a parallel-rack, multi-channel UAV payload dropper built around M18-class smoke canisters. It runs on 5 V, accepts PWM, light-sensor or remote-control triggering and mounts to the aircraft through a quick-release plate.

Q: What payloads does the M18SD carry? A: Each holder cup is sized for an M18-class smoke canister. Payload fit is confirmed by FlySpark for the end user’s approved payload before supply, and other items of similar size can be assessed on request.

Q: Which variants are available? A: Four channel counts: M18SD2 (2 channels, 67 × 200 × 160 mm, approx. 200 g), M18SD4 (4 channels, 133 × 200 × 160 mm, approx. 490 g), M18SD6 (6 channels, 200 × 200 × 160 mm, approx. 700 g) and M18SD8 (8 channels, 267 × 200 × 160 mm, approx. 900 g).

Q: What do PWM and SQ mean in the model code? A: PWM indicates the dropper accepts a standard PWM servo signal from a flight controller or receiver. SQ indicates the quick-release version, which mounts through a quick-release plate instead of fixed hardware.

• Q: What voltage does the M18SD need?
• A: All four variants operate on 5 V, which is available from most flight-controller servo rails, BECs and receiver outputs.

Q: How is a release triggered? A: Three trigger options are supported: a PWM signal from the flight controller or receiver, a light-sensor trigger that reacts to the aircraft’s bottom auxiliary light, or a remote-control trigger from a transmitter channel. FlySpark confirms the release sequence and channel mapping for your aircraft and trigger mode.

Q: How does the light-sensor trigger work? A: An optical sensor is fixed over the aircraft’s bottom auxiliary light. When the pilot switches that light from the flight app, the sensor detects it and commands the release, so no connection to the aircraft’s wiring is needed.

Q: Which drones is the M18SD compatible with? A: It is intended for heavy-lift FPV-class drones and custom multirotors using PWM or remote-control triggering, and for DJI Matrice M350-class enterprise multirotors using the quick-release plate and light-sensor trigger. Always check the aircraft’s rated payload against the dropper weight plus the loaded canisters.

Q: Which size should I choose for an FPV-class drone? A: The M18SD2 (approx. 200 g) and M18SD4 (approx. 490 g) are the practical choices for heavy-lift FPV-class frames. The M18SD6 and M18SD8 are better matched to M350-class enterprise aircraft with higher payload capacity.

Q: Is the quick-release plate included? A: The dropper-side quick-release seat is supplied as a free upgrade. The aircraft-side quick-release plate is sold separately and is selected to suit your airframe.

• Q: Can the M18SD be swapped between aircraft?
• A: Yes. With an aircraft-side quick-release plate fitted to each airframe, the same dropper can be moved between aircraft that share the plate interface.

Q: What are the dimensions of the M18SD8? A: The 8-channel M18SD8 measures 267 × 200 × 160 mm and weighs approximately 900 g without payload. All variants share the 200 mm width and 160 mm height; only the length changes with channel count.

Q: What is the M18SD drone dropper price in India? A: Price is on request because the final configuration depends on channel count, trigger mode and the aircraft-side plate required. Contact FlySpark on WhatsApp or email for a quotation in INR or for export.
