Here is a newcomer to the now big family of Cinewhoop, these nano racers capable of filming in HD and whose propellers are surrounded by protections. The HD140 is a device 14 cm diagonal from motor to motor which rests on a carbon structure of 3 mm thick, with a beautiful effort of decoration on the topplate. The motors are brushless 1305 to 3600KV for 2840 three-bladed propellers. At the heart of the system is a 20 x 20 mm mini-turn. On its ground floor, it is an ESC 4 in 1 of 20A. The F411 flight controller is just above, based on an F4 processor, flashed with Betaflight with an active OSD.
On the top floor is the 5.8 GHz video transmitter compatible with 48 channels, with a power of 25 mW (the maximum authorized in France) or 200 mW, with settings possible via the IRC Tramp protocol. The antenna is a polarized plugged into an IPEX connector. This transmitter broadcasts in real time the image of a Caddx Turtle V2 camera for immersion piloting. The camera films, at the same time, in 1920 x 1080 pixels at 60 frames per second by storing the video on a microSD memory card on board the camera. LDARC ensures that the propellers do not appear in the image field, with an angle of inclination of the camera adjustable between 15 to 50°. This camera is placed on shock absorbers to avoid unwanted vibrations.
The equipment of the LDARC HD140 is completed by a row of LEDs and a buzzer. Without receiver or battery, the device weighs 159.8 grams. The 2.4 GHz radio part is to be managed yourself if you want to install your radio receiver. You may prefer the version with an integrated multiformat receiver, the AC2000: it is compatible with the Futaba S-FHSS protocol, the FrSky D16 Non-EU and the D16 EU-LBT. To power everything, LDARC provides a 4S 430 mAh 80C battery with an XT30 socket. The device is delivered in a carrying case.
