Curious… Does the Antenna need to be visible? With mine, I did a test… I had the board upside down in front of me. With the remote hidden behind my back, I pull the trigger and nothing… I try again making the remote visible and it starts the motors. I immediately put it behind my back and it let go of the trigger. Nothing happens, it keeps spinning at high speeds. I then make the remote visible to the antenna and bam it immediately comes to a stop.
I didn’t think they needed that much of a line of sight?
