Mount the speed controller for the electric motor on the front face of the firewall, as
shown in the illustration.
Create a compartment for the flight battery by gluing the battery former in the
fuselage; the distance between the firewall and the battery former should match the
size of the flight pack.
Access to the battery compartment is obtained by forming an opening hatch in the
cowl.
The size of the hatch should be chosen to suit the battery you are using: cut three
slits in the cowl as shown in the photo: the left-hand cut should lie flush with the
outside of the motor dome. The hatch can be held shut with a strip of adhesive tape,
or by a pan-head screw and a piece of scrap wood, as shown in the picture.
Glue the piece of scrap wood to the inside of the cowl.
File a slot in the end of the hatch so that it can be slipped under the screw-head in
order to secure it, as shown in the photograph.
