MED 3115
The MED 3115 comes in six KV options and sits in the sweet spot: thrust for 7-13 inch propellers, low heating and a balance of power and weight. From low-KV units for long missions to high-KV units for FPV.
What the MED 3115 was designed for
Cargo delivery
Drones of 3-10 kg for last-mile logistics
Mapping and survey
A large payload for a camera or LIDAR
Industrial inspection
Power lines, oil and gas, infrastructure
Small agricultural drones
Sprayers and field scouting
Built to work where it has to
Protected against dust and splashing water. Operates in rain and in dusty conditions.
Guaranteed service life under normal operation with regular maintenance.
Stable performance in frost and in heat · for every climate zone.
Recommended set-up with the MED 3115
A ready combination of motor + ESC + propeller + battery for maximum efficiency.
