Guys,
Yesterday I had a problem with my CC Phoenix 45 ESC (CL mode - Set RPM @9200, running a Ztron II timer set for 100% throttle in all three settings,TP 4S1P 3900 Pro Lite pack), controlling a Hacker 30XL10 motor. I was doing some testing of the pusher vs. tractor props, had just done two 30 sec test flights with the pusher, after the second test flight I change two wires on the motor to reverse the motor direction; put on the tractor prop and did another 30sec test of the tractor prop, all went normal. Once I landed I wanted to do another test flight of the tractor prop, did not change anything, just let it sit about 30 sec after shutting off the power switch. On power up the ESC beeped as normal, 20 sec delay as I went to the handle then it got possessed!! The motor had reversed direction, it came up to just before full power and shut down. I tested it on the bench and changed props so that it had a prop for the direction it was spinning and powered up, the static amps went over 47 and it shut down (normal amps for this prop is around 34). I talked to my friend  Robert C and he had experienced problems with the CC45. He got a timer from Will Hubbert that has a voltage regulator built in to eliminated a voltage spike that seemed to fry the ESC.

I have run this timer and ESC for a little over 2 years with an AXI2826-10 motor with no problem, I only have 4 flights on the Hacker 30XL10 when this happened. Is this something particular to the Hacker motors? Has anyone had this happen? Could it happen in the air (real bad thing)?

Best.  DennisT

Hi Dennis,
It's just not possible for the timer to "fry" the ESC.
The other way around ... yes.
re-programming makes sense, but I'd watch this one carefully.

Glad things worked out.
