first replace the servo connecters if the progs are loose in them , and make sure the plug is in all the way .


let me guess you have the orginal, speckum system the gray one ? i have the same thing and all my, connections are tight and i even tried. to rebind it and it whould just shut off, when you have the engine running ? i even had foam in the radio box too .

i think its a bad computer chip in, it or something i sent out my to get repaired.
