Introduction

Thank you for purchasing the Quique Somenzini designed Byp Yak ARF Competition Indoor 3D/Precision Aerobatic model, which is based on his popular gas-powered competitive Yak aerobatic airplanes Quique designed this model to compete at top-level events such as the E-TOC and for nationwide demos. Quique uses his own unique A-frame design on the fuselage shape, which reduces flex in the more rigid fuselage giving you more precision control.

From super slow to top airspeed, flying the Byp Yak features a great combination of smoothness and precision, helping make this foam Byp Yak an extreme 3D flying performer like no other foam airplanes of this caliber. The Byp Yak

is capable of doing all the maneuvers that you have ever dreamt of and more.

New Foam

E-flite™ is introducing a new flat foam material with this aircraft. It is much more durable than other flat foams used in the past. We believe this will bring a higher level of success and enjoyment to your Byp Yak experience.

Alternative Radio Equipment

You will need a minimum 6-channel transmitter (for proper mixing and dual rate capabilities), crystals, micro receiver, and three sub-micro servos. You can choose to purchase a complete radio system that includes all of these items or, if you are using an existing transmitter, just purchase the other required equipment separately.

We recommend the crystal-free, interference-free Spektrum™ DX6 2.4GHz DSM™ 6-channel system, which includes a micro receiver and 4 sub-micro servos.

Important Information About

Motor Selection

We recommend you use the E-flite™ brushless outrunner motor Quique Somenzini uses on his Byp Yak. All of our flight tests were done using the motor listed below with the Li-Po battery listed below. Another alternative battery is to use the Thunder Power 730mAh 3-Cell 11.1V Li-Po Battery (THP7303SJPL) for extended flight time.

Using the Manual

This manual is divided into sections to help make assembly easier to understand, and to provide breaks between each major section.

Remember to take your time and follow the directions.

Warning

An RC 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.

Keep loose items that can get entangled in the propeller away from the prop, including loose clothing, or other objects such as pencils and screwdrivers. Especially keep your hands away from the propeller.

Before Starting Assembly

Before beginning the assembly of your Byp Yak, remove each part from its bag for inspection. Closely inspect the fuselage, wing panels, rudder and stabilizer for damage. If you find any damaged or missing parts, contact the place of purchase.

Note on Lithium Polymer Batteries

Lithium Polymer batteries are significantly more volatile than alkaline or Ni-Cd/Ni-MH batteries used in RC applications. All manufacturer’s instructions and warnings must be followed closely. Mishandling of Li-Po batteries can result in fire. Always follow the manufacturer’s instructions when disposing of Lithium Polymer batteries.

		Wing Installation
Required Parts
• Fuselage		• Wing strut (2)
• Lower wing		• Upper wing

•Strut reinforcement disk (14)

•.045” x 6" (1.15mm x 153mm) carbon rod (6)

•.045” x 13" (1.15mm x 330mm) carbon rod (2)

•.045” x 12 5/8" (1.15mm x 320mm) carbon rod (2)

Required Tools and Adhesives

• Foam-safe CA • Hobby knife

•Square

1. Place the fuselage on a flat surface. Use a square at the rudder to check that the fuse bottom and fin are square to each other. Lightly sand the bottom of the fuse where indicated if necessary.

10

 2. Test fit the lower wing to the fuselage. Place the wing onto the fuse bottom, aligning the servo holes in the wing with the servo holes in the fuselage. Carefully check to make sure the lower wing is square to the fuselage by measuring from the wing tip to the fin on both sides. Use foamsafe CA to glue the lower wing to the fuselage.

Note: You can use foam-safe activator to speed up the CA cure time.

 3. Locate the wing struts. Use a sharp hobby knife to remove the lower sections from the main section.

11

 4. Position the wing strut in the hole closest to the aileron of the bottom wing. It may be necessary to trim the reinforcement tape from the hole before fitting the strut. Use a square and foam-safe CA to glue both the wing struts into position.

 5. Place the top wing onto a flat surface. Position the wing struts and fuselage onto the wing. Hold the wing flat while gluing the fuselage and side force generators to the wing.

Note: It is recommended to use a square to check the wing strut alignment to the top wing.

Note: DO NOT glue the lower strut extension at this time.
