[Glytch] has been building drones since before they were called drones. Instead of submitting his time machine into the Hackaday Prize, he’s throwing his pocket sized, 3D printable coaxial dr…
CoaX Helicopters Limited was formed to commercialise coaxial rotor system technology into both manned helicopters and also unmanned Helicopters or RPAS (remotely piloted aircraft systems) / UAS / UAV drone. At Coax Helicopters we are currently harnessing this technology to design, develop, manufacture, market and distribute a revolutionary range of new Coaxial Rotor Systems into small

When you picture a consumer drone, something bulky with four or six props à la DJI probably pops to mind. But the folks behind a new model on Kickstarter think that such UAVs have two big problems -- namely, they're hard to carry and break easily if you mess up. They built The Sprite to overcome those limitations with a cylindrical, waterproof body and retractable blades. The design makes it easy to throw it into a pack, and when landing, the rotors halt in a half a second and fold into a retracted position. From there, the craft can safely alight on rocks, a bush or even a swamp without issues.

VERTICAL DOBLE BANDA PARA 144 y 430 MHz Es muy fácil de diseñar y se puede construir con tubos de cobre para mayor resistencia al viento o aluminio, dando buen resultado. La ganancia de la antena, según reportes dados, es de unos 5 dB de ganancia. A pesar de no ser mucho, hay que tener en cuenta que una antena de la característica de la Ringo, que tiene una ganancia de unos 3 dB. CONSTRUCCIÓN: La varilla inferior es la parte de UHF y es donde se deberá de conectar el vivo del cable coaxial, su longitud es de 49cm, pudiéndose usar tubos de cobre o aluminio finos, la parte superior de 97cm y corresponde a la parte de VHF. LA BOBINA: La bobina esta construida sobre un material aislante (tubo de PVC, resina, fibra de vidrio, etc.), de media pulgada de diámetro y 50 cm de longitud. Se deberá de poner un material aislante y que tenga resistencia al viento. Para realizar la bobina, deberemos tomar una medida de 2m 3cm de alambre de cobre de 1,5 mm de diámetro, dejad 2cm para poder conectar un extremo de la bobina a la varilla de UHF y el otro a la parte de VHF. Lo que hay que tener presente, en el momento de bobinar el alambre, la separación entre espiras debe de ser la misma separación entre ellas o lo mas aproximado posible.
