Overloading
DC motors heat up from the inside
out. If the casing is hot to your
touch, the internal components are
probably red hot. The larger the
aircraft, the more energy it takes to
move that load, causing heat build-
up. Slopes and rough terrain are
like moving a larger aircraft causing
more heat buildup. Moving aircraft
long distances also causes heat
buildup; excessive heat buildup can
damage the tug’s motor, drastically
reducing the tugs life span. We de-
signed Best Tugs™ tugs for intermit-
tent use. The larger the tug (with
an appropriately smaller than rated
load), the longer a tug can be in
continuous usage. If you must move
your aircraft a long-distance, slow
down, or pause now and then (See
Loaded Weight Tables) to allow for
heat dissipation.
Example 1: You have an R5 tug you
bought for your Meridian, and you
do your buddy a favor and move
their fully loaded King Air 350i—you
have just damaged the gears. Fail-
ure is now a matter of when—not if.
Example 2: You used the R5 tug
you bought for your Meridian, and
pulled your fully-loaded Meridian
up a 3-degree slope—you have just
damaged the gears. Failure is now
a matter of when—not if. The R8
would be a better choice. If you find
that you have the wrong tug for
your plane’s environment, please
call us and exchange it for the ap-
propriate model. We have a 30-day
exchange policy; you only pay for
the price difference and freight.
