has anyone had any problems with glitching? my Helios started doing it out of the blue, with either my 301's or 302 reciever. i did try both speed settings on the back. regardless of which car, motor, speedo, etc. and with everything else the same, my old Mars R worked perfectly.
this unit had been working flawlessly for about 4 months, then all of the sudden.... any ideas? i am debating sending it in for a check.
