I just did a E conversion on my lst xxl. When I turn off the transmitter first the car just takes off. I turned off the tx just to see what would happen if i lose reception. I don't want that to happen. What can I do to on to the tx so that wouldn't happen? Another thing is, Do I have to calibrate every time I turn on the receiver? It never seems to link unless i calibrate it. Thanx in advance..
