I recently fell and had a titanium plate and several pins put in my cheek, and can not wear my FPV goggles for some time. Saw these and thought I would give them a try so I could fly FPV without spending $700 + , . just received them, charged them up and installed them on my prescription glasses. Didn't work great as my glasses have a narrow frame. I installed it on the included glasses, worked great and was able to focus perfectly. The image is OK to fly slow FPV (for me), easy to tell orientation of quad. I can focus on screen and watch my quad at reasonable range by my preferral vision, or quickly switch back and forth. I really do love these. I purchased these, I did not receive them free.

A saturação da cor é um pouco plana, como é comum. e o peso da unidade é suficiente para que você precise de um equilíbrio no lado dos gases opostos. Mas permite FPV enquanto mantém o drone na linha de visão, conforme exigido pela FAA nos EUA. A bateria parece atingir uma capacidade máxima de cerca de 88%, o que não é bom, considerando que tem 25 minutos a 100%. A JJRC recusa-se a vender baterias sobressalentes. Então fiz o meu, o que foi fácil. Abri a bateria, confirmando que era um Lipo 2S padrão 7.4V, não era nada de especial, a JJRC podia tê-los vendido por grandes lucros. Remontei a caixa e fiz um molde dela em borracha de silicone, usei resina de uretano para fazer cópias, fiz furos para os fios da bateria e usei tubos de cobre, bolas de solda, epóxi pr condutivo para pastilhas. A polaridade é mostrada em imagens. Não estragues tudo, provavelmente vai fritar tudo. Usei um Lipo ZOP Power 7.4V 400mAh 2S da Banggood para o ligar. 2,5 vezes a capacidade e é o peso perfeito para um contrapeso dos óculos. Funcionou muito bem, como mostra as fotos. Você tem que carregá-lo com um carregador de equilíbrio, mas você precisa de um para baterias de drones de qualquer maneira.

The color saturation is a bit flat as is common. And the weight of the unit is enough that you need a balance on the side of the gasses opposite it. But is allows FPV while keeping the drone in line of sight as required by the FAA in the U.S. The battery seems to max out at about 88% capacity, which is not great considering it has 25 minutes at 100%. JJRC refuses to sell spare batteries. So I made my own, which was easy. I opened the battery, confirming it was a standard 7.4V 2S Lipo, It was nothing special, JJRC could have sold them for big profits. I reassembled the case and made a cast of it in silicone rubber, used urethane resin to cast copies, drilled holes for the wires from the battery and used pipes of copper, balls of solder, pr conductive epoxy for pads. Polarity is shown in pictures. Don't screw it up, it will probably fry everything. I used a ZOP Power 7.4V 400mAh 2S Lipo from Banggood to wire it up. 2.5x capacity and is the perfect weight for a counterbalance on the glasses.. It worked great as shown in the photos. You have to charge it with a balance charger, but you need one for drone batteries anyway.
