Here something cool for those of you who have cleared E4.

You can cheaply and quickly rank up your planes using E5. To do this load up all the planes you want to rank up they can be ground based aircraft, fighters, bombers whatever. Set the mode to sortie on all squads. Deploy 4 DDs to E5. Set all your planes to attack A. Then clear the node and then retreat. Repeat until all your planes are rank7.

You use about 12 fuel per sortie and your planes dont take air raids on node A. Takes about 10 or so sorties to rank7 your planes.

Have fun!~
