Weird Problem!

Both Hobbywing ESC's I have give the same problem, when plugged in, sometimes on powerup, there is no power powering the receiver - no lights, no steering. But the fan ontop of the ESC is spinning fine.

However, if I unplug my transponder from the ESC, then power comes back to the servo and I get drive again. If I plug the transponder back in, then the power to the receiver stops :S!

Now this first appeared on my extreme stock a few months back (so it got put in the pit box) and I started using my SP2.0lpf again trouble free with no issues at all. Then my new 120a got put in the car yesterday and did a full days practice with no problems (using 119 mod). Today I had 119 stock on the esc and the problems started with this ESC.

It seems to much of a coincidence that my 2 Hobbywing ESC's brought 4 months apart have the same problem that seems so-far unfixable and completely random. If this was a regional or national event I would have missed my final!!!.

Any help or suggestions?
