2020-05-31 — Common Raven Testlights 30.05.20
2020-06-05 — Common Raven Flight in Rain 04.06.20 — from heavy load and hard flapping a balljoint melted….
2020-06-08 — Common Raven Gliding Test 08.06.20
2020-06-13 — Common Raven Gliding Test 13.06.20
2020-07-11 — Common Raven last flight 16.06.2020 — test of gliding system. after some flight a connection to rc receiver was lost, the flightcontroller didn’t jump into failsafe mode causing the raven to go back into a forest…
2020-12-10 — Common Raven (corvus corax) Maidenflight 10.12.20 — Receiver: FrSky mini 8ch Flightcontroller: Arduino Pro Mini+MPU6050 Gears: 8t0.5Mpiniongear,56t0.5Mspurgear-7t0.5Mpinionwire,69t0.5Mmaingear Motor: 2211 2300kv brushless motor ESC: 12A simONK control: 2x D56MG digital metal gear servo material of wing membrnane: black Skytex 27
2020-12-11 — Common Raven (corvus corax) test flight 11.12.20 — Receiver: FrSky mini 8ch Flightcontroller: Arduino Pro Mini+MPU6050 Gears: 8t0.5Mpiniongear,56t0.5Mspurgear-7t0.5Mpinionwire,69t0.5Mmaingear Motor: 2211 2300kv brushless motor ESC: 12A simONK control: 2x D56MG digital metal gear servo material of wing membrnane: black Skytex 27
2021-01-14 — Turbo Raven (corvus corax) Test flights 14.01.21 — The amplitude of hand wing flapping has been reduced because in this wing design it resulted in poor lift. by new setting the model can fly fast and furious. also a glide lock was installed which when enabled allows entering a glide mode when throttle is below a threshold: https://github.com/dantiel/arduino-flight-controller
2021-06-12 — RiotRaven Wing Update first testflight 12.06.21 — the Wing Base Broke by Stronger Wings and hard flapping which need to be strengthened motor: TBS 6s 1800kv Raven motor Wingspan: 1.6m Gears: 14t0.5m pinion, 80t0.5m Aluminium spurgear, 7t0.5m pinionwire, 85t0.5m maingear Control: 2x MG90S gyro: HOBBYEAGLE A3 V2 receiver: FLYSKY3chan battery: 370mah 4S lipo Weight: 370g (with lipo)
2021-06-16 — RiotRaven testflight 15.06.21
2022-03-01 — Servo raven II test flight 27.02.22 — a new raven model with spread pinion feathers that fold in the correct angle , for more optimal airflow. flapping is harmonic , but too weak for climbing servos: 2x ROBSG HS1106S battery: 300mah Turnigy plus 2S lipo
2023-10-17 — TurboRaven TestFlight 17.10.23 — The model was repaired and the rear part of wing was enforced because thrust was low, now a part of the front wing also needs enforcing, possibly this might eventually require a stronger motor
2023-11-22 — TurboRaven TestFlight 21.11.23 — the middle part of wing was strengthened, but this made the model slower because the angle of the middle wing was already too steep. another solution needs to be found, also this model keeps on breaking because it was build more lightweight.
2026-08-22 — Krawallrabe — this is a little bit older flight video. i added some humorous music created with suno.com
