BATTERY CHARGER

FOR SAFETY AS WELL AS PERFORMANCE, CHARGE LIPO
BATTERIES ONLY WITH A LIPO BATTERY CHARGER!  
In  addition  to  providing  the  critical  charging  profile  needed  to
safely charge lipo batteries, a lipo battery charger also includes
the capability of "balancing" the available voltage in the cells, en-
suring that the battery pack is at peak capacity at the end of the
charge cycle.  This translates to better flight times and a longer
life from the battery pack.

Your T-CLIPS  ARF  is  covered  with  ORACOVER®,  a  premium
quality  covering  made  in  Germany,  and  sold  in  the  U.S.  by
Hanger-9 as Ultracote®.

Colors Used On Your Airplane

ORACOVER® #23 Ferrari Red (Ultracote® #HANU866)

and

ORACOVER® #71 Black (Ultracote® #HANU874)

If  sometime  in  the  future  you  need  replacement  covering  or
matching paint for repairs, they are available from your local hobby
dealer or online from Hanger-9.

How To Tighten Loose Covering

After you open your T-CLIPS and take all the covered parts out of
their plastic bags, the covering may begin to wrinkle.  This is not
unusual and is no cause for alarm.  Your airplane was built and
covered in a part of the world which has relatively high humidity
and therefore, the wood was likely carrying a fair amount of mois-
ture.  When exposed to drier air, the wood typically loses this mois-
ture, dimensionally "shrinking" in the process.  In turn, this may
cause some wrinkles.  However, wrinkles are easy to remove by
just using a hobby type heat iron.  

Caution: Trying to remove the wrinkles by hastily going over them
with a heat gun can lead to more problems.  You should take your
time to carefully go over the entire model with a covering iron, as
we will describe.

We suggest  using a model airplane covering iron for this process.
Cover the iron's shoe with a thin cotton cloth, such as an old t-
shirt, to prevent scratching the covering as you work.
