Introduction
Thank you for your purchase of Hangar 9’s Extra 330L. Because the size and weight create a higher degree for potential danger, an
added measure of care and responsibility is needed when building and flying giant-scale models. If this is your first giant-scale
aerobatic aircraft, it’s important that you carefully follow the instructions, especially those regarding hinging (pages 9–10), sealing the
hinge gaps (pages 11–12), and the section on flying (pages 33).
Like all giant-scale aerobatic aircraft, the Extra requires powerful, heavy-duty servos. Servos greatly effect the flight performance, feel,
and response of the model. To get the most out of your Extra, it’s important to use accurate, powerful servos with a minimum of 80 oz/in
of torque. In the prototype models we used JR 8101s and JR 8411s with excellent results. A less powerful servo can lead to a crash.
The Extra 330L does not include hardware. Many experienced giant-scale pilots have specific hardware preferences and can
individually choose the components that they prefer. Hangar 9 offers an optional hardware package (page 5) part (#HAN1220, JR/
#HAN1221, FUT) that includes the hardware that our staff regularly uses and recommends.
Throughout the manual, the above hardware will be used during the assembly process. If using another type/brand of hardware, it’s
your responsibility to be sure that it’s strong enough for this application and properly installed.
If you encounter difficulty in any construction sequence, please contact one of our technicians. We stand ready to provide any
assistance we can concerning the construction of your Extra 330L. Contact us at:
