I have just built a Lite Machines electric helicopter. I have a 7 cell Sub C, 3000 mAh battery pack, brushed Kyosho Atomic Force 17 turn motor, and a GWS ICS600H ESC. The ESC has a BEC and I am running 3 micro servos. My problem: The motor starts and runs fine at any speed, but when I start moving the servos around the motor shuts down. I can get it to shut down almost every time by working the servos. Sometimes it takes longer than others. The servos continue to work after the motor shuts down. There isn't a low voltage cut-off on the ESC so it shouldn't be shutting down for voltage reasons. Any thoughts or suggestions? Thanks for the input!!

What type of ESC is it? The fastest solution would be to replace the ESC.

Ya, unless it is programable, there is really nothing you can do except change the esc. Make sure your batteries are fully charged. Might try doing a test spool up with one or two servos installed and see if it still does it. Mabey its one of the servos
