Post Mortum on the HK G15 950Kv motor:
Striped the motor this afternoon to see if I could find the cause for the failure.
Although the motor was only drawing 42 amps at full throttle and I spent almost no time at that setting at all. I found that 6 of the outer race magnets had epoxy failure and had slid back about 2 mm and were rubbing on the rear casing. Not very impressed as the thing had only done 8 or 10 flights, most of those were about 60% throttle or less with the odd burst at full throttle for 5 to 8 seconds.
I checked the motor temperature after every flight and I was able to keep my fingers in contact with it without burning. I recon it was coming down at no more than 50 degrees C tops.
Conclusion: You get what you pay for, must have been a Friday afternoon built motor!!!!!

Hopefully the G25 (that is on the way as a replacement) will not have similar issues as it is a much heavier build and is designed to run a much larger prop. Slightly lower Kv at 850 but will hopfully cope with the load.
Time will tell.................

850kv Equals 10x10 apc prop running 4s lipo at about 40 amps.

Similar setup to what i had on my 1.2 hking p51 marie i had, and it flew great.
