Alright
. The motors are ready and they'll be shipped on Monday. SpEEdyBL was right on the money with the Kv values. Here is what Bob has just sent me:
"Here are the KV tests I did on the two motors.
Input voltage measured at Speed control power input
Motor Vin Aload KV
2.5 5.0 3 7900 Free running (no load)
2.5 4.0 30 7125 Loaded
2.5 5.0 43 6960 “
2.5 6.0 57 6700 “
2.5 7.0 73 6515 “
1.5 5.0 9 12,630 Free running (no load)
1.5 4.0 91 9750 Loaded
As you can see the 1.5 is pulling a lot of current at 4 volts so I did not want to run it at any high load. My suggestion would be to run the 2.5 for most of your runs and then use the 1.5 for the last few runs in case it blows up.
We will ship the motors Monday."
