Have you been paying attention?
You say the leashes are equal length, yet less agile heavy bombers can pull a mauever while keeping in formation that your light more agilr buffs can not?
I can not take you seriously if you present evidence that contradicts your original statements.
I will explain it better then. The Boston III is so fast and maneuverable, that if a maneuver like an immelman is pulled the plane goes up and over so fast that the drones cannot keep up, and when they finally do make it up and over they explode because of the "leash" they are on is so short that they cannot keep up. To pull this maneuver off successfully I would need to either slow down, which is not a good thing to do in a medium bomber, or not do it at all. Some might say that the plane was not meant to pull such extreme maneuvers, and I can comply with that. But I also like to dogfight with the Boston III after I had made my bomb run, and the drones will not keep up with me on the sharp turns. Remember, this wish is not for a longer leash (although that would be appreciated), but for an RTB button for the drones.
