The servo draws a lot of power just sitting and holding center. If it is drawing enough to max out the BEC, hitting the gas is just going to draw it down all the more. This is a VERY well known and often discussed problem with Savox servos. Fortunately, some ESC manufacturers are starting to address it by building in more powerful BECs but only a few.
