Viper 15"

Massive frame designed for building a long-range drone or Cinelifter, capable of carrying up to 15" propellers. The frame features a large body with ample space for all necessary electronics. The arms are CNC cut from 10mm thick and 24mm wide T300 carbon. Each arm includes M3 threads for mounting accessories or reinforcements (not included). The frame supports motors with 19mm M3 and 30mm M4 mounting patterns. The inner height of the body is 25mm, which can be increased by replacing the standoffs with longer ones.

The top plate offers space for battery mounting with dedicated cutouts for LiPo straps. The frame accommodates either two batteries side by side or one larger pack with a maximum width of approx. 10cm and length of approx. 15cm. It also supports slim, long batteries with a width of approx. 6cm and length of approx. 27cm.

The front section includes carbon side plates for Micro-size cameras. Alternatively, a 3D-printed mount (not included) can be slid onto the front standoffs.

Behind the camera bay is space for electronics with mounting patterns of 20x20mm, 25.5x25.5mm (M2), or 30.5x30.5mm (M3) – typically AI boxes or FPV camera systems. Two M3 threads with 62mm spacing are available for payload mounting. A cutout for a buzzer is located directly behind the stack space.

The top section also provides a cutout for a USB-C connector and two additional M3 threads with 37mm spacing.

In the center section, there is space for the main stack with flight controller and optional 4-in-1 ESCs. This bay supports 30.5x30.5mm stacks only. Additional M3 threads on the bottom allow for payload mounting or 3D-printed add-ons.

The rear section provides space for video transmitters with mounting patterns of 20x20mm, 25.5x25.5mm (M2), or 30.5x30.5mm (M3), as well as two M3 threads with 62mm spacing. The top plate also features 20x20mm M2 mounting holes for top-mounted video transmitters. Openings are prepared for mounting two XT60EW-M connectors. Included is a 3D-printed holder for XT90 connector, SMA antenna, and RC antenna.
