Inside the hopper.

RESILIENCE · Flight Computer
RP2040 OBC running custom Rust firmware. IMU, BMP390 baro, flash + microSD logging.
HARMONY · Telemetry
RN2483 LoRa link to ground station — flight state, sensor stream, command channel.
VITALITY · Power Distribution
22 V → 5 V buck. Routes power to OBC, servos, telemetry. Reusable across hopper and rocket configs.
LiPo 6S — 22 V · 4000 mAh
Single battery feeds the ESC for the EDF and the avionics chain via the regulator.
EDF · 70 mm Ducted Fan
10-blade alloy fan, 2300 KV, 1.75 kW continuous, 2.8 kgf peak — driven through a 100 A ESC.

SECTION 03 — Control system

Three axes. Two actuators. One fan.

TVC · Pitch
Servo Y vectorises the EDF nozzle in the pitch plane to command forward/aft attitude.
± 8°
TVC · Yaw
Servo Z vectorises in the yaw plane. Independent heading control during hover.
± 8°
RCS · Roll
Dedicated mid-body fan ring authorises roll, the one axis the TVC cannot reach.
± 360°/s
