Both planes can be made from the same single sheet of Dollar Tree foamboard. The paper is removed after the parts are cutout. The motor mounts right about where it did on the full-scale planes. The fuselage simply pulls apart exposing the battery. Because the thrust is forward and the servo is behind the motor the fuselage can be separated for servicing or battery change.
I will finish installing this weekend.
Plans will be ready after testing in a couple weeks.
