man, i had to watch the flight vid over again a few times, man, i think i was high enough to have done a tight circuit to kill alt, and i could have made a normal landing on one motor. crap. freakin 20 20 hindsite bull crap. also, after watching the video, and seeing andys fly as well, i think mine would be every bit as fast as andys with my current power setups. so i think im going to get a new motor to replace the one with the improper kv, and get another cc 120ice controller. while not the most powerful setup by any means, i think it will fly the model in a scale like fasion, and have decent flight times. i feel the motors with proper kv will live just fine. the motor with the proper kv looks to have handled the power no problem. so ill try that route befor ei go spend a ton of money on bigger fans and motors.

C/N Did you ever run the motors with a watt meter? Or just an approx guess on Kw?

around 5kw. i do need to check the CC ice 120, to see if it still has the data from the flight, though the ice controllers typically are off by about 5-10% on amp draw, but rpm should be correct.

I don't think you can blame yourself Nut. You did a great job getting it down on the runway and if it hadn't been for the cable at the end you wouldn't have had half the damage. ( Why are those cables there anyway, they don't stop anything but airplanes!)Like I said before, if you had been at a dry lakebed then you wouldn't have any damage.
And I think anyone who saw the smoke pop out of it would have made the same instant decision.

I smoked a ESC in my 60" Cessna 182 and I did the same thing nut, came in too hot and ran out of runway. I was in a panic cause it was on fire.

Yup, I applied and got hired, it was a needed change of pace and lifestyle. We wanted a stable CONUS assignment, and the B-2 fit the bill. Its a great lifestyle so far, lots of time for RC and my 8 month old boy, plus I get to fly the B-2 and the T-38.

I definitely need to, some other guys were out there this weekend, but I think they stopped at PMD.

ok so i looked at the data in the ice controller from the flight. revealed that i was just about exactly where i thought i was. settled to about 110A, 5100W or so.

i also discovered that i think the one motor is 1400KV. i didnt have a ice on that one, so theres no way to tell what it was pulling in flight.

Did you look in the burned up controller to see which bank burned up. If its a single bank it could be because of a shorted motor phase or a feedback issue from the motor disrupting the switching of the controller. If its more than one bank it could be because of over current.
Anyway does CC repair controllers? I have repaired some controllers by replacing a bank of FET with To220 or SO 8 packages (irf7413 or similar). I do not have the equipment for the smaller packages.

it was a turnigy 120. th entire board was smoked. it got so hot, it unsoldered the power wires and the motor wires from the board. pretty crazy, ive never seen that happen. since i was apparently running a 1400kv motor marked as a 1200kv motor, im sure i was 130A+ probably more. if i would have known that, i wuld have never tried to fly it. goes to show you should always check amp draw.
