FlySpark LD35 Multi-Channel Hanging Drone Payload Dropper | 2/4/6/8-Channel Parallel Release, 35 mm-Class Cylindrical Payloads, Quick-Release Plate, PWM / Remote Trigger, 5 V & Single or Half-Load Salvo

FlySpark LD35 Multi-Channel Hanging Drone Payload Dropper is a parallel-rack release unit that carries 2, 4, 6 or 8 35 mm-class cylindrical payloads under a drone and releases them on command, one at a time or half of the load at once. It hangs from the airframe on a quick-release plate, operates at 5 V and is triggered by a standard PWM servo signal from the flight controller or directly from an RC receiver channel, so it integrates with FPV-class drones and DJI M350-class enterprise drones without proprietary electronics.

The LD35 is part of the FlySpark UAV Payload Droppers & Release Systems range, supplied and supported in India by AnuShakti Infotech Pvt. Ltd. for defence, government security, public-safety and professional integrator customers, with export enquiries welcome.

Every variant shares the same 104 mm width, 52 mm housing height, 5 V supply, PWM / remote trigger and quick-release interface; only the length changes, growing 50 mm for each extra pair of channels: 94 mm for the LD35-2, 144 mm for the LD35-4, 194 mm for the LD35-6 and 244 mm for the LD35-8. Each cup has its own latch, and payload fit is confirmed by FlySpark for the end user's approved payload.

WHY CHOOSE THE LD35 MULTI-CHANNEL DRONE DROPPER

The LD35 puts up to eight payloads on one compact rack, so a single sortie can cover several drop points or deliver a group of items together. The standard PWM interface means it works with any flight controller or receiver that has a spare servo output, and the quick-release plate lets crews swap the dropper between aircraft or remove it for transport in seconds. A slim 52 mm housing keeps the payload close to the airframe for a low centre of gravity.

HOW THE LD35 DROPPER WORKS

The pilot assigns a transmitter switch to the drop channel. The command reaches the dropper as a PWM servo pulse, either through a flight-controller auxiliary output or straight from a receiver channel (remote mode), and the latch servos open the selected cups. In single mode each command releases one payload for precise, sequential drops; in half-load salvo mode each command releases half of the loaded payloads together, so two commands empty the rack. Power is 5 V from the aircraft BEC or a regulated servo rail.

COMPATIBLE AIRCRAFT & MOUNTING

The LD35 hangs under the aircraft on a quick-release plate. The dropper-side quick-release seat is included as a free upgrade, and the aircraft-side plate is matched to the airframe and sold separately. Typical carriers are FPV-class drones (7–10 inch class quadcopters and custom multirotors) for the 2- and 4-channel versions, and DJI M350-class enterprise drones or larger multirotors for the 6- and 8-channel versions. Always stay within the aircraft's rated payload and centre-of-gravity limits.

Never fly over people, confirm the drop zone is clear before every release, and do not exceed the aircraft's rated payload.

FREQUENTLY ASKED QUESTIONS

Q: What is a multi-channel drone payload dropper? A: A multi-channel drone payload dropper is a release unit that carries several payloads side by side under a drone and lets the pilot release them one at a time or in groups from the remote controller. The FlySpark LD35 carries 2, 4, 6 or 8 payloads in a parallel rack.

Q: What is the FlySpark LD35? A: The FlySpark LD35 is a multi-channel hanging drone payload dropper for 35 mm-class cylindrical payloads. It mounts under the aircraft on a quick-release plate, runs on 5 V, is triggered by a PWM or remote (RC channel) signal and releases either a single payload or half of the load per command.

Q: Which variants are available? A: Four variants: LD35-2 (2-channel, 94 × 104 × 52 mm), LD35-4 (4-channel, 144 × 104 × 52 mm), LD35-6 (6-channel, 194 × 104 × 52 mm) and LD35-8 (8-channel, 244 × 104 × 52 mm).

Q: What payloads does the LD35 carry? A: It is designed for 35 mm-class cylindrical payloads such as inert training cylinders, marker and signalling canisters, beacons, sensor capsules and small rescue items packed in a 35 mm-class tube. Payload fit is confirmed by FlySpark for the end user's approved payload.

Q: How is the LD35 triggered? A: By a standard PWM servo signal, either from a flight-controller auxiliary output or directly from an RC receiver channel mapped to a switch on the transmitter (remote mode). The unit operates at 5 V.

Q: What release modes does it support? A: Single release (one payload per command) and half-load salvo (half of the loaded payloads released together). On the LD35-8, for example, a half-load command releases 4 payloads and two half-load commands empty the rack.

Q: How does the LD35 mount to the drone? A: It hangs under the airframe on a quick-release plate. The dropper-side quick-release seat is included as a free upgrade; the aircraft-side quick-release plate is matched to the airframe and sold separately.

Q: Which drones is the LD35 compatible with? A: FPV-class drones (typically 7–10 inch class quadcopters and custom multirotors) and DJI M350-class enterprise drones, using an aircraft-side plate matched to the airframe. Always stay within the aircraft's rated payload.

• Q: Does the LD35 support light-sensor or CRSF triggering?
• A: No. The LD35 is a PWM / remote unit. Light-sensor (auxiliary-light) and CRSF-serial triggering are offered on other FlySpark droppers.

Q: What are the dimensions of each variant? A: All variants are 104 mm wide and 52 mm high; length is 94 mm (LD35-2), 144 mm (LD35-4), 194 mm (LD35-6) or 244 mm (LD35-8). Length grows by 50 mm for each additional pair of channels.

Q: What is the weight of the LD35? A: Weight depends on the variant and the quick-release hardware fitted; it is confirmed with the quotation so you can check it against your aircraft's payload budget.

• Q: What is the power requirement?
• A: The dropper operates at 5 V, normally taken from the flight-controller BEC or a regulated 5 V servo rail on the aircraft.

Q: What is the LD35 drone dropper price in India? A: Price is on request because the configuration (channel count, aircraft-side plate and integration support) is matched to each buyer. Contact FlySpark on WhatsApp or email for a quotation in INR or for export.

Q: Can I fit the LD35 to a DJI Matrice 350? A: Yes, M350-class aircraft are supported through an airframe-matched aircraft-side quick-release plate (sold separately). FlySpark advises on plate selection and on wiring the trigger signal for your aircraft.

Q: Which variant should I choose? A: Choose by payload count and aircraft lift: the LD35-2 and LD35-4 suit FPV-class drones, while the LD35-6 and LD35-8 are better matched to larger multirotors and M350-class aircraft with more payload margin.

Q: Can the LD35 be used for search and rescue? A: Yes. It can drop small rescue items, marker canisters, beacons or radios packed in a 35 mm-class tube to people or teams in the field, one at a time or in groups.

Q: Can other payloads be integrated on the LD35? A: The LD35 is supplied as a general-purpose payload release unit. Integration of any other authorised payload is the responsibility of the verified end user and must comply with national law, export controls and procurement rules.
