Hi -

I had a chance to work on the airplane and as it turns out, the controller is an ICE HV 80. Paying attention to the the beeps, I noticed that I was getting 3 beeps followed by a pause. I looked it up and it is an indication of an over current condition. While doing the run up, I had hooked up a watt meter which only read about 5 amps before the motor stuttered and stopped. I tried the ESC on a different motor and got the same result.

I was able to hook up the controller to the Castle link and download the data which I have enclosed. Looking at it, the controller seems to think that I was hitting 120 amps in the 800 or so seconds which were recorded. The initial portion of the recording might correspond to the last flight before the controller went bad. The plane is propped for a max current of about 70 amps so seeing the 120 amp in the log seemed surprising. I believe that the data is not correct as I do not remember the last good flight as being unusual. At the end, the batteries took back about 3000 mah which was normal consumption based on my previous experience (Advanced sequence plus a few extra maneuvers at the end; total flight time of about 7:30 minutes).

The motor I use is a Pletty Evo 25-12. The prop is a 20x13 carbon fiber. So now I am wondering a few things:

1) I suspect that a capacitor has failed due to the weak spark when I arm the system.
2) I wonder if the motor and prop combination is to blame... The 20x13 is at the limit of what plettenberg recommends for the motor; probably too big on 10S.
3) Are the motor and controller a good match, or would I be better off with a different controller.

Either way, I will be sending the controller in for repairs, I believe that it needs them. Any insight or suggestions would be appreciated.

Thank you,

Teo
