If you don't need the digital servo capability then buy this one. It's the same but doesn't have the servo selection type capability. I bought this for my Honey Bee CP2 and locks the tail like elmer's glue. It's a Telebee Gyro. Do the math and save $39 dollars for something you'll need for your Heli.
