Required tools and Materials

This Extreme Flight RXR aircraft requires your Transmitter, Receiver, Lipo Battery and any adaptor you need
to connect to your Lipo battery. Your 67” RXR comes with an XT-90 battery connector installed. A variety of
adaptors are availble to convert to nearly any battery connector.

You will also need thin CA glue and basic hand tools. We also recommend a threadlocker, such as Loctite
blue #242.

When using CA glue, if you spill excess glue onto
your airplane, we recommend Acetone (available
at hardware and home improvement stores) and
a paper towel to clean.

Before ight, you should use a covering iron to run over all of the covering seams and stripes
on your aircra, and as your airplane is exposed to sunlight and the airframe adjusts to your
location, wrinkles will appear in your covering. You can shrink these wrinkles out of the cover­ing with a covering iron or heat gun. If you have never worked with covering before, we rec­ommend you watch a covering video, such as our Extreme Flight 60” build video on YouTube,
