When you select the gear up on say a 744, how many doors open prior to the gear retracting? Those open doors cause drag, which is what oggers is referring to.
Airmann - The 787-9 has a 'pre doors' function, whereby the gear doors open upon liftoff, in order to reduce retraction time once the gear is actually selected up. That may well defeat what you may be trying to achieve.
