Purchased 2 pro systems and an extrw receiver at the urging of my racing buddies. One of the receivers would go into fail safe about every other battery and usually at the end of the straight. Tried rebinding any # of times with no good result. Sent that one in for repair or replacement. Another receiver started fsing on me just recently, but only once or twice a race day. One has been flawless. I have Jr R1 Tx's and run Jonson 540 (mabuchi) motors with approx. 1/3 the amp draw of standard stock motor. I'm getting a little nervous . So far haven't broken too much but-----. Should I send the other receiver in also??? Am I the poor schmuck that just happened to get 2 faulty rceivers?????
