Thanks Bob! . You have a dual drive like I do so it can be steered via the motors. I used a Sabertooth 2x60 motor controller, an RC controller with an Ardupilot in between, all the typical parts you would find a quadrocopter/ RC car. Remote range is great (line of sight) and there is an app that allows the pilot to be managed via tablet/smartphone. If you ever need more info on how I wired it all up just let me know.
