Redux Air Raven 5-Inch Race Frame

The Raven is the product of our Electronic Speed  Controller (ESC) theory, and subsequent frame development program. ESCs can be designed to be a specific size, make a certain current output, or for durability. Due to the available semiconductor technology, and thermodynamics, it is only possible to choose two of the aforementioned characteristics of an Electronic Speed Controller. We choose power and durability. In drone racing you need repeatability which means practice and also durability and not having to worry about catching fire in heavy competition. This means we needed bigger ESCs. We still wanted to be as light as possible, and be as well balanced as possible for accurate control. Most frames were designed to be one-size fits all, or had size limitations with the intent on weight savings. Our solution was to do the exact opposite of popular racing drone frames and design a 20x20 frame that could fit, and offer protection a 30.5x30.5 or 20x20 stack with a big ESC. 20x20 ESCs wi
