Pilotix PT-15 Lite

Pilotix PT-15 Lite is a 15" frame suitable for building a long-range drone. The diagonal motor spacing is 610 mm. For good durability and rigidity, the arms are cut from 9 mm thick carbon and connected to each other with carbon braces. A carbon part is placed between the arms to prevent arm movement. The arms themselves are secured with two screws for easy replacement.

The frame is ready for use with separate ESCs, which have reinforced space on the arms for easy installation. This shortens the motor wires and the ESCs are well cooled by the airflow from the propellers.

The frame consists of a bottom, middle and top plate. The middle plate has space in the center for mounting a stack with 30,5 x 30,5 mm mounting pattern or a flight controller with 20 x 20 mm mounting pattern. Thanks to the ample space, larger 4-in-1 ESCs can also be used. At the rear of the frame there is space for mounting a video transmitter. For easy installation, mounting holes are available with 30,5 x 30,5 mm (M3), 25,5 x 25,5 mm (M2) and 20 x 20 mm (M2) spacing. The front part has the same mounting holes and additionally a 40 x 40 mm (M2) spacing for mounting AI boxes of some FPV cameras. The frame includes a 3D printed holder for mounting a Micro-size camera. There is enough space between the standoffs to fit even larger cameras, including DJI O4 Pro.

The top plate can accommodate batteries up to 26 cm long. In its rear part there is another set of mounting holes for attaching a video transmitter. A 3 mm thick non-slip battery pad can be attached to the top plate.

Both plates are made of 3 mm carbon. The space between the middle and top plate is 35 mm. The overall dimensions of the frame are 460 x 405 mm. The frame includes a 3D printed holder for an SMA connector, ELRS antenna and two Lipo straps measuring 45 cm.
