Here are some EagleTree DataLogger graphs using the 6350-16T and an APC 20x13 prop, TP5300 batteries. The motor ran well, never got hot and it was pulling a near 11 lb plane. It would probably work well if your plane was 10.25 lb or less but I think it would struggle if it were heavier and the wind picked up.

The first graph is an exploded view of a short time frame (a few seconds) to show volts/amps/watts and rpm. The second is for the entire flight.

Great data Don,

It looks like the efficiency of the smaller motor is not as good at these currents. The Watts, current, etc., are acceptable if it were a 20x15 or 22x12. I guess it figures, as the length of the motor is less, meaning less torque for a given current vs. the longer motor. You don't get something for nothing. It would probably pull a lot more current with the bigger props and that accounts for John F burning one up.

Woodie, 5 minutes for the P-07 man thats quick or at least for me and pulling 67 amps my AXI 5320/28 would never stand for that it would be squeeling like a pig LOL, good info Don. I been wanting see some figures on this motor also.

This was just a test flight, not the full P07 sequence. I did a portion of the sequence but not all since I just wanted some logged performance data. Actually, I was somewhat surprised the smaller motor did as well as it did. It would probably be fine on a lighter plane with a smaller prop.

Ok kool I think your right about the motor I like my little AXI 5320/28 but will be trying a couple of the daulskys this fall at there prices how could I not experiment. I kinda wondering what the 12T would do at 310 KV.

Thanks for the info...very helpful. I am the guy working with John F on his Black Magic. The 6360 is really the way to go on that bird. He is flying the larger motor now and is much happier. We will be outfitting John with the brand new Vampower Platinum Series 5S 5000 X 2 next week. We are really excited about the contests coming up.
We did cut the prop back in size for the 6360 and found that the new 20.5" E to be ideal in terms of amp draw and airspeed. This has a little more penetration in higher wind according to John.
Peace

I just recieved the 12T and will be tsting it in the upcoming weeks. I am wanting to try the CC 85HV with the motor and see how it goes.

I am running the 16T currently and have had good results when i can keep it running, but struggling currently with it jumping timing?? out of sync etc. I am going to try the CC and see if i can clear this up.

John, what controller are you using and what are your option settings?

thanks in advance..

The controller is the Jeti Opto 90. We card programmed it on the Eglin flightline a bit ago and set the timing to High for outrunners. If you use anything else the timing will experience pulse crashing. At the high timing the motor performs well. We will go to the Dualsky HV90 as soon as the new firmware versions get there this week. Earlier versions of the controller were not able to be timed high enough and pulse crashing resulted. The HV90 is very robust controller with four hard mount holes for it. It has a very large heat sink too and a generous signal wire for the receiver.
