As advertised – POWERUP 3.0/DART Review

Works great! The artificial horizon, as the other review states, does respond backwards, but if you're looking at that, your aircraft probably has already "bought the farm"-- you're watching the aircraft anyway so this is just a cosmetic thing. A little rc background helps but all in all, this is a great product and with 2 units, you'll be constantly airborne or better yet MEL!
