Hello,

I have a new turnkey FeiBao L-39 and I am having problems setting up the Jet-Tronic brake valve. When I attempt to fill the system with air, all of the air leaks out of the other holes on the valve. (See pictures). Any idea as to what I am doing wrong? The open and close function seems to work correctly based on the red / green lights and movement of the slider on my transmitter. Any help is greatly appreciated!

Thank,

Chris Wilson
