T-Motor M690 Long Endurance Quadcopter Drone



This listing (Ebay: https://www.ebay.com/itm/T-Motor-M690-Quadcopter-Drone-60-Min-Time-for-DJI-Pixhawk-Ardupilot-etc/193901327648) is for a lightly used T-Motor M690 Quadcopter Drone. These currently sell new for $1800. It was previously used for long-endurance mapping using a custom Pixhawk autopilot and carrying a Sony a6000 camera. Note, there are holes that were drilled into the top plate of the airframe body and top cover to mount the previous electronics. Additionally, a mount for a removable Drotek RM3100 compass mast (great compass by the way) was adhered to the top red cover. Neither modifications affect functionality, and the original mounting threads for DJI, Pixhawk, and Micropilot flight controllers are untouched.

This drone includes a CNC machined aluminum airframe body with power board, carbon fiber motor arms with integrated motors, ESCs, and nav lights. It has foldable landing gear, a carbon fiber red top cover, payload mounting threads, GPS mast, and compass mast (for the RM3100).

This drone is capable of flying for 1 hour with a 1kg payload. It normally uses a ~30AH 4S smart battery made by Tattu, but I believe that you can also used a normal LiPo 4S battery (with an XT60 plug) that fits into the battery bay. The smart batteries can be purchased from T-Motor’s website or a number a T-Motor distributers. I am unable to include any batteries due to shipping restrictions unless you do a local pickup.

Hi @lyon44,
I think this is very good quad, please confirm that the motor is MN5004 Kv300 ?
I like the quad.

@ton999
The motors are 5004 Kv500, spinning 18*6 props on 4S.

@lyon44 Thank you for quick response. Is the frame foldable? From the pictures, seems it is not. Or you must disassembly the arms to travel?
Regards

@ton999 It does not fold. Here is the link to the product page which has more information: https://store-en.tmotor.com/goods.php?id=831
