Step 7: EDF install
The position of the EDF in the DragonFly is
unique and makes your aircraft quite
efficient for an EDF model. To begin the EDF
install, assemble your motor and fan unit in
the usual manner. Make sure that the collet
is fully secure on the motor shaft and that
the rotor runs true and balanced. Also route
the motor wires through the side of the EDF
unit as depicted. You will need to drill a 6-
7mm hole in the wall of the EDF housing to
accomplish this. Once you have fed the
three motor wires through this hole, solder a
male bullet onto each.
Secure the EDF unit to the fuselage using
four short wood screws. For added
efficiency, add the EDF inlet shroud should
be glued in place using a few drops of CA
glue.
Next, attach the plywood motor mounts
using strong CA glue or epoxy as shown.
Remove a portion of the fuselage as
depicted on the right to allow passage of the
ESC/motor wires. Connect your ESC and
ensure that your fan rotates in the correct
direction. Tidy up the cables, perhaps using
small cable ties.
