helo0...question for anyone who can help...I just built a new plane..and was testing the electronics and I knotced that when i activate the alerion servos to fast..the motor power dips down. Now, because the servos are running off the flight battery, im assuming that they are sucking more juice then they should??...If i move the servos really fast..i can practically bring the prop to a stop!!...i have 3 other planes and ive never seen this problem b4....anyone know whats up?

Maybe put a ampmeter in line to C just how much the servo is drawing the compare to a bare servo maybe a bad servo even. CU

Thanks...acutally i did some investigating and realized that the speed control that they came with my package was rated for 7cells/three micro servos...8 cells/2 micro servos.....im running 8 cells with "4" micro servos...sounds like it could be the problem..anyone concur?

Could be but servos don't draw that I just tryed it a 300 standard
servo draws about 200 mills bare.2 amp unless they bottom out. CU

It sounds like your battery is not capable of producing the Amps necessary to run everything. The added load from the servos causes the battery voltage to drop, and the low-voltage circuitry to kick in.

If the ESC is rated for X servos, you can't use X+1 servos. The BEC will get hot and burn out.

figured it out...the person who put my package togheter had no clue what they were doing and my speed control was way underated....i fixed the problem...went brushless!!
