hi all,please help,im going nuts,i have fitted an mtroniks failsafe to my marder,only when i power up the throttle goes on full and i have no trigger response,but if i carry on going through the set up,kill my tx, the throttle will go straight to neutral,every time,then comes the weird bit,the sreering starts going erratic turning as it likes rapidly,if i switch the tx back on,it returns to normal opperation,i have checked the connections,even brought a new failsafe,but to no avail,i am running it as it is at the moment,but i dont trust it as it isnt right,can anyone shed any light on this,its driving me booloo. regards
