reinstalling a stock tail boom)
some frames the tail boom is secured to the frame and tail
housing with set screws. These are the easiest ones to work on. On
other frames the parts are glued together. Usually they can be
separated by running them under very hot
water, or soaking them in boiling water, for 3 or 4 minutes, then
twisting them back and forth until they release. It helps to
wear gloves with a grip pad on the palm and fingers or using a
rubber pad the like the blue one in step 4 below. Trying this
method first could save you a lot of time. But, don't forget to
remove the electronic components before soaking the frame in water
hot water doesn't work, you can try wetting the parts with a
liquid "debonder" made to release the
CA bond. It's sold at hobby shops.
If either of the above procedures work, you'll already have
removed the electronics and can skip steps 1 through 4 below. If
not, you'll have to cut the tail boom from the frame and tail
housing by following all the steps below. There is a risk that
you'll ruin your frame or tail housing and will have
to buy new ones.
should be taken that you don't injure yourself !
procedure for installing a SuperBoom, or a stock tail boom,
is the same.
|1. Unsolder the wires from the tail motor and pull them through the
boom. It's also recommended that you remove the tail motor from
the tail housing (although it's not done in some of these
pictures). IF you've
managed to fully remove the tail motor wires beforehand, you can use a small hacksaw or razor saw to cut the boom
flush with the frame or tail housing. Otherwise, use pliers to crack the stock carbon fiber tail boom.
Rotate the pliers all the way around the boom, cracking it in
several places around its circumference. About 40% of the time, I've found that
while cracking the boom with pliers, I was lucky and some of the
boom inside the housing was also splintered and was removed when I
broke the boom free (see picture below). This made cleaning out
the hole a bit easier.
When the CF boom is cracked, it will splinter
and can be broken off as shown above.
|3. Clean out the splintered boom with pliers, a hobby knife (as
shown) or a screwdriver or any other suitable method. You want the
remains of the old tail boom to be flush with the hole so you can
start the drill bit in the next step.
a 3/16" drill bit to clean out the hole. You can use a drill,
pin vise, or rubber mat to hold the drill bit. The blue mat in the
above picture is made for opening jars, but it works great for
holding the drill bit. If you use an electric drill, the job will
go faster, but there's also a bigger risk that you'll damage the
frame or tail housing.
you've cleaned the hole with the 3/16" bit, use a 5mm bit to
enlarge it. If you don't have a 5mm bit, you can wobble the
3/16" bit to enlarge the hole. Don't make it too big. You
want a fairly snug fit.
|5. Run your tail motor wires through the frame first, then the
SuperBoom, and finally into the tail housing. The SuperSkids
logo is designed to be near the frame. Make sure the logos on each
side of the boom are level, put a couple drops of CA glue on the
end of the boom and push it into the frame. Slide the tail motor
wires back and forth a couple times to make sure you didn't
accidentally glue them, and let the glue dry for a few minutes
before you install the tail motor housing.
you install the tail motor housing, you want to make sure it's
plumb. The tail rotor shaft should be perpendicular (90°) to the main
rotor shaft. Put another way, the tail rotor (blade) should be parallel to
the main rotor shaft, plumb to the ground.
you're an experienced pilot with a reason to do so, never have the
tail housing rotated clockwise (drifts forward), and never have it
rotated more than 1° counter-clockwise (drifts backward).
