What about first draining the External ones and dropping the External Fuel Tanks after they are empty, then switch to the regular. This will probably give you some extra range and speed.

Thanks for uploading this! Even thou 0.15 has just arrived this craft is already exelent. You made this faster than I could create a properly functioning plane (without tipping on the runway or spinning in mid-air). You sir, need a medal. By the way, I would like to have some Extended-Extended Range Kerbalfortress, one without any weapon and the possibility to carry more fuel and go further.
