are crafted with the best materials and modern techniques to make
them almost unbreakable, and to avoid the problems associated with
other landing gear.
built-in passive suspension was carefully engineered to absorb most
impact forces without transferring it to your helicopter's frame.
After all, even unbreakable landing gear isn't a bargain if it
allows or causes damage to your helicopter. The shape, materials,
and even what appears to be decorative relief cuts, are all integral
parts of the suspension. Since not all helicopters weigh the same,
we can control how stiff the landing gear is by adding positive
camber to the top bar.
now, most landing gear engineering consisted of "make it
softer", "make it stiffer", or "make it shorter
and fatter, and to heck with the tail rotor". The 2 primary
styles were the "straight leg" and the "bowed
leg" designs, and each has it's own problems.
most common type of landing gear is the "straight leg"
design. It transfers more impact force to the frame than the other
designs. Besides causing damage to the frame, it's also the
most likely to break; generally just above the skid hole, or where
the legs meets the top bar.
you crash (or land hard) at an angle, one leg may break and one
side of the frame may be damaged. If you're unfortunate enough to
come down straight, both legs may break and even more damage may
be done to the frame. If the landing gear break, there is no
further protection for the tail boom, fin and rotor.
other common landing gear is the "bowed leg" design.
Some thought (but not much engineering) has gone into these in an
attempt to overcome the problems with "straight leg"
designs. Generally, if they do break, it's near the skid
design flaw is that it has to be soft to absorb any shock, but it
has to be stiff if you don't want the heli to bottom out. Since it
can't be both, manufacturers choose one or the other. There are
some on the market that are short, fat and stiff. Most of these
aren't tall enough to keep the tail off the ground, and they do
little to absorb shock. Others on the market are too soft. One
that's sold as 450 size landing gear won't even support the weight
of a 400 size helicopter. It depends on the tail fin to support
the back of the helicopter. A stiff "bowed leg" design
won't help to protect your frame, and both styles easily allow
damage to your tail boom, fin and rotor.
passive* suspension in SuperSkids400 helps to protect your
helicopter's frame whether you hit straight down or at an angle.
Impact shocks are directed away from the frame and absorbed in the
landing gear. Our unique "alligator leg" design is
engineered to flex within in the suspension area. The amount of
spring tension needed for heavy or light helicopters is controlled
by the camber of the top bar. This helps to protect the tail boom,
fin and rotor, as well as the frame.
A passive suspension is one that reacts to forces. Most automobiles
use a passive suspension system.
