Introduction; Warning - Hangar 9 Sukhoi SU-31 Instruction Manual

Introduction

Thank you for purchasing the Hangar 9
Because size and weight create a higher degree for potential danger,
an added measure of care and responsibility is needed for both
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 and the section
on flying. Like all giant scale aerobatic aircraft, the 1/3-Scale
Sukhoi Su-31 requires powerful, heavy-duty servos. Servos
greatly affect the flight performance, feel, and response of the
model. To get the most out of your Su-31, it's important to use
accurate, powerful servos with a minimum of 80 oz in of torque
for elevator and rudder and 60 oz in of torque for each of the
four aileron servos. In the prototype models, we used JR 8101
and JR 8231 servos with excellent results. A less powerful servo
can lead to a crash.
The 1/3-Scale Sukhoi Su-31 does not include hardware. Many
experienced giant scale pilots have specific hardware preferences
and can individually choose the components they prefer.

Warning

An R/C aircraft is not a toy! If misused, it can cause serious
bodily harm and damage to property. Fly only in open areas,
preferably AMA (Academy of Model Aeronautics) approved
4
® 33% Sukhoi Su-31. Hangar 9 offers an optional Hardware Package (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.
