I have an electric combo with an AXI motor that the max is 22 amps.  I will pull that at peak rpm/throttle.  I can hold this, according to AXI specs, for 60 seconds, and 15 amps at 75% throttle.  I have a 30 amp Jeti controller.  The battery is a 2S 2150 amp rated at 20C discharge rate.The motor, and battery seem like they get to a "normal" temperature" while testing with a Watts Up Meter.  The controller seems like it got pretty hot....... and this was not using up the full charge on the battery. Does this sound like there is a problem with the controller ..... or is this kind of normal??.  I hate to guess at the temperature for this posting....but it does get noticeably hotter than the battery does.  .....thanks in advance...... lownslo

PS.  I have GOOD cooling holes for entry and exhaust.....plus the controller hatch was off for the test. The battery hatch was in place.

Chuck,
I did some more monitoring with the Watts Up meter.  I tried the same set up as before and the controller hardly got warm.  It still pulled a peak of 23 amps at full throttle initially but soon dropped to the max allowed for 60 seconds. (22 amps). I then tried a 9-5 instead of the 9-6 I had on there, THIS TIME without the aluminum spinner cone I have for nose weight needed.  It now pulled only 16 amps at 100% throttle. I put the weighted cone back on and I noticed NO difference in read-outs.  I have NO idea why my controller got so warm the first test last week.  Ambient temps were warmer then..........but not enough to warrarnt the difference I noticed.  .....Oh well....  I do think I will get some 9-5 props and use them on the maiden flights.  Moto-Calc was not real "happy" with the 9-5's...... but in holding the plane while running, it felt like it had plenty of power.  ...... lownslo....
