if i use these servos, will they fit and plug right in,or do i need to buy something more than 4 servos(ex. BEC)?
No you do not need a BEC, these are cheapo non digital servos. The wire length is the issue on these, just on the aileron servo. With the TowerPro SG90 you can move your RX over a little and get the wire to reach. You may do well shopping around for a servo extension, shortest you can find would be fine as we are talking an inch.
