, modern, flashy helicopters abound. So it's fun and impressive to see DIY projects, like OskarRDA's, literally take flight.
In one of his recent videos , OskarRDA demonstrated his helicopter's electric tail rotors in flight mode. The original tail rotor was a traditional drive-shaft one before he chose to switch it for the seven electric ones.. The helicopter only needs four 5008 or 5010 size motors with 18-inch props to deliver a thrust comparable to the traditional drive-shaft.
According to the blog post, the helicopter is an ultra-light Mosquito Air kit fitted with a two-stroke engine that OskarRDA turned electric using an The helicopter's battery capacity is 7.8kWh, which means that when hovering the power required is 21kW, so the battery will last 22 minutes. When flying just above 12.4 mph the power required is 17kW, so the battery lasts 27 minutes.
As mentioned, it's exciting to see inventors showcase their creations, and this all-electric helicopter is no exception. In the above video, watching the small helicopter cruise steadily back and forth, up and down, above the tarmac fills you with a sense of thrill and awe.Just enter your email and we’ll take care of the rest:
حلم قاسم عام 2015 - قال النبي محمد صلى الله عليه وسلم ، أن قاسم، انقل هذه الرسالة إلى الأمة كلها ، فمن يقف معك هو مثل شخص يقف معي ، ومن يدعمك فهو كما يدعمني. أعتقد أن قاسم سيكون الإمام المهدي.
