Rotorama Hornet

Rotorama Hornet is our racing frame, developed with our team pilot Petr Horák. The Hornet aims to be durable, fast, and practical. For optimal flight characteristics, the frame features a True-X configuration. The body is cut from standard carbon T300 to maintain an affordable price. The stressed arms are cut from premium 5mm thick carbon Toray T700, which offers greater strength. The pointed arm ends, a signature feature of Rotorama frames, provide proven motor protection during crashes. The arms are paired and secured using two screws. They are fastened with a locking nut that can be tightened securely.

The frame uses a bottom and middle plate cut from 2mm carbon, which increases the overall rigidity of the frame. It is also possible to replace the top plate with a 3D-printed canopy. The frame supports stacks with hole spacing of 20x20mm as well as larger 30.5x30.5mm, which is not very common for racing frames. The stack has a height clearance of 24mm, and if more space is needed, the standoffs can be easily replaced with longer ones. There is a dedicated slot between the bottom and middle plate for threading the LiPo strap, ensuring that the regulator does not come into contact with the strap, minimizing the risk of damage in case of a crash.

When using 20x20mm stacks, the entire screw can pass through the bottom plate, including the head (for 30.5x30.5mm, only a screwdriver can go through). The arms are secured with countersunk screws, creating a smooth and sufficiently large area for securely mounting the battery.

The frame can be equipped with both analog and digital video transmission using a nano-size camera. The top plate is sufficiently wide (35-38mm), protecting sensitive digital video transmitters. It includes 20x20mm M2 and 30.5x30.5mm M3 mounting holes for easy installation of the video transmitter or other electronics.

The entire frame weighs 66 grams including 3D-printed parts. The frame comes standard with a front fin, Foxeer Lollipop Micro antenna mount, and a universal Nano camera mount. Additional accessories can be found on Thingiverse, where they are continuously updated.
