Transporting
It is best to keep the WSC aircraft in an enclosed hangar, but
trailers may be used to transport, store, and retrieve the WSC
carriage. If the trailer is large enough, the wing can also fi t
inside the trailer. If not, then it must fi t on top of a trailer,
truck, or recreational vehicle (RV). [Figure 5-9]
Enclosed trailers are preferred so the carriage is protected
from the outside elements such as dust, rain, mud, road debris,
and the interested person who may want to tinker with the
carriage. The WSC carriage should fi t snuggly without being
forced, be guarded against chafi ng, and well secured within
any trailer. It is best to utilize hard points on the carriage
frame and secure each wheel so the carriage cannot move
fore and aft during transport. This is best accomplished by
fi rst tying the front wheel from the axles, the fork, or a hard
point on the frame with a slight forward pull. Then, secure the
rear wheels from the axles or a hard point on the frame with
a slight rearward pull. Guides on the side of the wheels and
wheel chocks in front and back of each wheel are additionally
helpful to secure the carriage on any trailer.
The wing must have ample padding and should have at least
three support points where it rests for transport. Transporting
the wing properly is of critical importance because the wing
resting on any hard surface can wear a hole in the sail and
cause structural damage to the tubing. The greatest wear and
tear on a wing can occur during transportation. Each support
point should have equal pressure—no single point taking
most of the load. The wing should be tied down at each
attachment point to secure it, but not tight enough to damage
the wing. Wide straps are better than thin ropes because the
greater width creates less concentrated pressure on the wing
at each tie-down point.
Once the loading of the carriage and wing is complete
[Figure 5-9], take a short drive, stop, and check for rubbing
or chafi ng of components.
Prior to taking the tow vehicle and trailer on the road, inspect
the tires for proper infl ation and adequate tread. Ensure
all lights are operable, the hitch is free moving and well
lubricated, the tow vehicle attachment is rated for the weight
of the trailer, and the vehicle and trailer brakes are operable.
Avoid towing with too much or too little tongue weight,
which causes the trailer to fi shtail at certain speeds, possibly
rendering it uncontrollable.
Be extremely cautious when unloading the wing and carriage.
This is best done with two people since the wing usually
weighs more than 100 pounds [Figure 5-10] and the carriage
usually must roll down some incline to get from the trailer
to the ground. Some carriages may be tail heavy without the
wing, and caution must be exercised, especially moving up and
down ramps. Check propeller clearance on the ground when
transitioning onto or off of a ramp and propeller clearance going
into and out of an enclosed trailer. If the carriage is transported
in an open trailer, it should be covered and the propeller secured
so it does not rotate/windmill during transport.

Setting Up the WSC Aircraft
Find a suitable area to set up the wing, such as grass,
cement, or pavement out of the wind. Inside a large hangar
is preferable since wind gusts are not a problem. If setting
up outside, align the wing perpendicular to the wind.
Most wings set up with the same basic procedure shown
in Figures 5-11 through 5-33, but the POH should be
referenced for the specifi c WSC aircraft.
Rotate the wing bag so the zipper is facing up. [Figure 5-11] Unzip
the bag. When setting up the wing, pay close attention to
the specific pads, where they are located, and how they
are attached for each component of the wing. As shown in
Figure 5-12, the padding is made specifically for the control
frame between the downtubes and the control bar. If every
