The M300-to-M350 refresh cycle is flooding the used market with documented ex-fleet aircraft — and choosing between them is now purely a requirements exercise, not a budget gamble.
Head-to-Head
| M350 RTK (used) | M300 RTK (used) | |
|---|---|---|
| Flight time | 55 min | 55 min |
| IP rating | IP55 | IP45 |
| Batteries | TB65 (400-cycle rated) | TB60 |
| Transmission | O3 Enterprise | OcuSync Enterprise |
| Payloads | H30 series, L2, P1, PSDK | H20 series, L1, P1, PSDK |
| Typical used price | ~$6,899 ex-fleet | ~$3,900–5,200 |
Choose the M350 If the Program Is Long-Term
IP55 weather sealing, the newer transmission, TB65 longevity economics, and H30-series payload access make the M350 the platform you build a 3–5 year program around. Ex-fleet used M350 RTKs with full service logs are the strongest value in enterprise drones right now — see why supply is peaking.
Choose the M300 If Budget Drives
The capability overlap is bigger than the price gap suggests: same airframe class, same flight time, H20 payloads still excellent for inspection and public safety. A documented used M300 RTK under $4,500 is an extraordinary amount of enterprise capability per dollar for a first program.
The Non-Negotiable Either Way
Ex-fleet documentation, not flight hours, decides quality: complete logs, battery wear percentages per pack, and payload-port condition. An M300 with a full service file beats a low-hour M350 with a story. Both platforms in our catalog ship with the fleet log and our enterprise warranty.
