Cowling
10. The top of the cowling has no bolts and is easily removable for access to the battery
compartment. It is held in place with 2 magnets and hooks. Locate the radial engine piece and
trial fit the piece into the bottom half of the cowling. Notice there are two notches in this piece
and they fit to the upper portion of the cowling. It should fit with no shaping necessary.
However, it is wise to sand the areas that will mate to the bottom section of the cowling to
enhance the glue joint. We also suggest cutting a hole in the center of the piece to allow your
choice of motor to protrude, cut as necessary. Once the trial fitting is satisfactory, glue in place.
We used foam tac, however epoxy, welders adhesive as well as other adhesives will work. We
only glue the radial engine piece to the bottom half of the cowling, the top half does not receive
any glue because it has to be removed for battery access. See figures 29 and 30.
