Construction Manual

WARNING

READ THROUGH THIS MANUAL 

BEFORE STARTING CONSTRUCTION. 

IT CONTAINS IMPORTANT WARNINGS 

AND INSTRUCTIONS CONCERNING 

THE CONSTRUCTION AND USE OF THIS 

MODEL.

A Radio-Controlled aircraft is not a toy!

If misused, it can cause serious bodily harm 

and damage to property. Fly only in open 

areas, preferably at AMA (Academy of Model 

Aeronautics) approved flying sites, following all 

instructions included with your radio, powerplant, 

electronics and batteries.

• Inspect your model before every flight to ensure it is airworthy.

• Be aware of any other radio frequency user who may present an 

interference problem.

• Always be courteous and respectful of other users in your 

selected flight area.

• Choose an area clear of obstacles and large enough to safely 

accommodate your flying activity.

• Make sure this area is clear of friends and spectators prior to 

launching your aircraft.

• Be aware of other activities in the vicinity of your flight path that 

could cause potential conflict.

• Carefully plan your flight path prior to launch.

• Abide by any and all established AMA National Model Aircraft 

Safety Codes.

IMPORTANT!!! 

Two of the most important things you can 

do to preserve the radio controlled aircraft hobby are to avoid flying 

near full-scale aircraft and avoid flying near or over groups of people.

ITEMS NEEDED

Hardware needed (not included in the kit) 

For some of these items there is more than one option which will 

require a bit of decision making ahead of time. There isn’t a right or 

a wrong choice, so choose the items that work best for you. 

We strongly recommended supporting your local hobby shop.

•  Powerplant: .61 sized 2-stroke glow engine (or similar electric 

system)

• Propeller

•  Engine/Motor mount and mounting hardware

•  10 ounce Fuel Tank and fuel tubing

•  Receiver - (4 channel minimum)

•  4 servos (electric) or 5 servos (if glow) - we recommend standard 

servos all around, although you can use a smaller servo on the

•  Pushrods (two 5” for ailerons, two 32” for elevator & rudder, 

one 14” for nose gear steering, one 10” for throttle if glow.)

•  Clevises for the pushrods.

•  Wheels: one 2-1/2" for nose, two 2-3/4” for mains.
