The BEC has to do with the provision of power to the receiver through the ESC using the motor's battery. Otherwise you would have to have a second battery for the receiver. The BEC data (5 V/4 amps) has to do with the voltage provided to the servos and the maximum amperage that can be provided through the ESC to the servos. Those values have nothing to do with the LVC. The LVC is the voltage at which the ESC cuts off the motor to ensure the battery has enough power (volts and amps) to run the receiver and servos. Thus allowing you time to get the plane back onto the ground before you lose all power and, subsequently, control.

I will run the specs for your power system through motocal when I get home this evening and see what the model says about amp draw and post another reply.

You may have indicated before, but, what is the brand of ESC? I need that information to make the modelling more accurate.

P.S.: I just ran the numbers on a simpler model software and came up with an amp draw of around 54 amps. This assumes you are running direct off the AXI, i.e. no gearbox. If that is the case, you are mostlikely drawing more amps than the GP3300s can provide and greater than the motor's design maximum. I believe the GP3300s have a recommended maximum discharge rate of 10C or 33 amps and the AXI 2810/10 has a maximum design draw around 42 amps for 60 seconds. I need to check my specs, but I believe they are very close to correct. I will still run the numbers on my more detailed software when I get home this evening.

P.S.S.: Well, I ran the numbers on my motocal software and got a 38 amp draw assuming direct drive. I really believe you are drawing more amps than the battery can provide without a significant drop in voltage. When the voltage drops due to the amps drawn at WOT the LVC is triggered stopping the motor. When you decrease the throttle, thereby, reducing the amp draw, the voltage recovers to a level above the LVC. Once the voltage is above the LVC, the ESC allows the motor to restart. When you increase the throttle again to a point that the amp draw pulls down the voltage below the LVC, the process starts again. I believe you may need to either adjust the prop to lower the amp load at WOT or change batteries to ones which can handle the WOT amperage.

I hope this helps../////Danny
