KAVAN Vibe - Instruction manual

Introduction

Congratulations on your purchase of the high-performance 3D aerobatic model VIBE. You are about to start assembling a model manufactured from almost unbreakable EPP (expanded polypropylene) foam, powered by a powerful brushless motor and lightweight LiPo battery. Everybody, who has already mastered flying a "full-house" trainer with aileron, elevator, rudder, and throttle control, will enjoy this beast.

Before you start

1. If you are not an experienced RC pilot, plan to have a fully competent pilot check your completed model and help you with your first flights. Even though we have tried to provide you with a thorough instruction manual, RC models are rather complicated, and an experienced modeller can quickly check over your model to ensure your first flights are successful.
2. Please assemble your model according to these instructions. Do not modify or change your model in any way. Doing so may adversely change its flying characteristics.
3. Before you begin, check the entire contents of this kit to make sure no parts are missing or damaged. It will also help you to become familiar with each component of your plane. If you find that any of the parts are either missing or damaged, contact your dealer immediately for replacement.
4. Note: Your dealer cannot accept kits for return if construction has begun.
5. Trial fit each part before glueing it in place. Before assembling, make sure you are using the correct part and that it fits well. No amount of glue can make up for a poorly fitting part.
6. The manual contains a drawing showing the default Centre of Gravity (CG) position and recommended control surface throws. Please note it is essential to keep the recommended CG position for the first flight, or the model could be unstable, hard to control or even unable to fly. Later, you can fine-tune the CG position to suit your flying style and skills.

SAFETY PRECAUTIONS AND WARNINGS

• An RC aeroplane is not a toy! If misused, it can cause serious bodily harm and damage to property. Fly only on a safe place, following all instructions and recommendations in this manual. Beware of the propeller! Keep loose items that can get entangled in the propeller away from the spinning propeller, including loose clothing or other objects such as pencils and screwdrivers. Ensure that your and other people’s hands and face are kept away from the rotating propeller.
• As the user of this product, you are solely responsible for operating it in a manner that does not endanger yourself and others or result in damages to the product or the property of others. This model is controlled by a radio signal subject to interference from many sources outside your control. This interference can cause momentary loss of the controls, so it is advisable to always keep a safe distance in all directions around your model, as this margin will help to avoid collisions or injury.
• Never operate your model with low transmitter batteries.
• Always operate your model in an open area away from power lines, cars, traffic, or people. Avoid operating your model in populated areas where injury or damage can occur.
• Carefully follow the directions and warnings for this and any optional support equipment (chargers, rechargeable batteries, etc.) which you use.
• Keep all chemicals, small parts and anything electrical out of the reach of children.
• Moisture causes damage to electronics. Avoid water exposure to all equipment not specifically designed and protected for this purpose.
• The model is made mainly of plastic - it is not fireproof. It may not be exposed to higher temperatures, otherwise severe distortion of the foam airframe or other damage may occur.

Technical specifications

Wingspan	1000 mm
Length	1030 mm
All-up weight	750–800 g

You will need

• At least a four-channel RC kit, a power unit with 3-4S LiPo flight pack and servos - refer to "Recommended power systems and servos."
• Regular modeller‘s tools: modeller‘s knife, screwdrivers, pliers, electric drill with drill bits, No. 180–360 sandpaper, etc.
• Glue: medium and thin CA glue, accelerator for CA glue, hot melt glue.

RECOMMENDED POWER SYSTEMS AND SERVOS

• Sunday 3D: For 3D aerobatic beginners and Sunday flyers.
• 3D: For everybody who likes it hot and 3D.

Note: 40–50A ESC with a good linear BEC should be OK if you are using analogue servos. However, if you are using high-torque & high-speed digital servos, you should go for an ESC featuring powerful switching SBEC.

RC kit installation and pre-flight check

• Refer to the instruction manual of your radio and carefully hook up the on-board electronics. The correct linkage length and control surface neutral position - refer to assembly steps 37, 43 and 45.
• Once everything is correctly connected, turn on your transmitter and plug in the flight pack. Check the neutral positions and throws of all control surfaces. If you need to make the control surface throws smaller, simply move the pushrod closer to the centre on the servo arm, or move it farther from the control surface on the control horn. And vice versa.

Recommended throws	Low rate		High rate
	Rate	Expo	Rate	Expo
Ailerons	± 20°	30–40 %	± 35° or more	40 %
Elevator	± 30°	30–40 %	± 50° or more	40 %
Rudder	± 35°	40–45 %	± 47°	45 %

• The „Low Rate“ recommended control surface throws are suitable for a less skilled pilot and classic pattern aerobatics; the „High Rate“ setting is for 3D aerobatic and skilled pilots.
• Check the direction of rotation of the propeller. If it is incorrect, swap two of the tree wires between the ESC and motor or program the ESC (refer to the ESC manual).
• Attach the flight pack to the side of the bottom part of the fuselage using a strip of hook-and-loop tape to get the correct position of the centre of gravity (CG) 85 mm, refer to Fig. 69. You can fine-tune the CG position later in order to suit your flying style.
• Fully charge your flight pack and transmitter batteries, check the proper function of your radio and perform the range check of your radio according to its instruction manual. The range has to be almost the same with the motor off and at full throttle (no more than 10% decrease is acceptable). DO NOT try to fly unless the range check is 100% successful.

Flying

The test flying and fine-tuning is pretty much straightforward. There will be no surprise for a medium-advanced pilot that is supposed to fly this model.
