Only 1.8" long, the 4-output, next-generation Raven has all the features (and then some) you would expect from the most powerful flight computers on the market, but compared to its closest competition, it's less than half the size and significantly less expensive.   You can fly it right out of the box using the default redundant dual-deployment settings for the outputs, or use the easy-to-use Featherweight Interface Program to set up any staging or airstart events you can dream up.
