Introduction

The Savage Max V2 is a kit for a 3D aerobatic model made from carbon-reinforced EPP (expanded polypropylene) foam. Its large control surfaces and all-moving tailplane suit pilots who have mastered a trainer with aileron, elevator, rudder and throttle control. The motor, ESC, radio, flight battery and four servos are selected and installed by the builder.

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 make sure your first flights are successful.
2. Please assemble your model exactly according to these instructions. Do not attempt to modify or change your model in any way, as doing so may adversely change its flying characteristics.
3. Before you begin, please check the entire contents of this kit to make sure that no parts are missing or damaged. This 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, please contact your dealer immediately for replacement.
4. Trial fit each part before glueing it in place. Make sure you are using the correct part and that it fits well before assembling. No amount of glue can make up for a poorly-fitting part.
5. The manual shows the initial centre of gravity (CG) and recommended control throws. Use the specified CG for the first flight; otherwise the model may be unstable, difficult to control or unable to fly safely. See the pre-flight section before making any later adjustment.

Note

Your dealer cannot accept kits for return if construction has begun.

Safety precautions

This RC model is not a toy. Use it with care and strictly following the instructions in this manual.

Assemble this model following strictly these instructions. DO NOT modify or alter the model. Failure to do so, the warranty will lapse automatically. Follow the instructions to obtain a safe and solid model at the end of the assembly.

Children under the age of 14 must operate the model under the supervision of an adult.

Assure that the model is in perfect condition before every flight, taking care that all the equipment works correctly and that the model is undamaged in its structure.

Fly only on days with a light breeze and in a safe place away from any obstacles.

General warnings

• An RC aeroplane is not a toy! If misused, it can cause serious bodily harm and damage to property. Fly only in a safe place and follow 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 faces, and animals 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 damage to the product or the property of others. This model is controlled by a radio signal that is subject to interference from many sources outside your control. Interference, equipment failure or pilot error can cause loss of control, 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 mostly made of plastics – it is not fireproof. Keep it away from heat sources, direct sunlight and hot enclosed cars; high temperatures can distort the foam airframe or cause other damage.
• Disconnect the flight battery whenever the model is not in use. Even at zero throttle, the ESC draws current; leaving the battery connected for hours or days can deeply discharge it, damage it and create a fire risk.

The linkage templates on pages 18–19 of the supplied printed manual are at 1:1 scale. Use them to position the servo-arm extensions and set the control surfaces to neutral. Do not measure lengths from a resized image on screen. (Fig. 35) (Fig. 36) (Fig. 46) (Fig. 58) (Fig. 82) (Fig. 83)

Wing and horizontal fuselage

1. Join the front and rear horizontal fuselage parts with medium CA. Leave the marked nose opening unglued for the firewall. Identify the upper and lower faces from the tail-bearing cut-outs. (Fig. 1) (Fig. 2) (Fig. 3)
2. Glue both wing panels to the fuselage with medium CA, keeping their profiles aligned with the horizontal fuselage. Cut the spar slots 6 mm deep on both faces and fit one 5×1×1000 mm carbon spar on each face with thin CA. (Fig. 4) (Fig. 5) (Fig. 6) (Fig. 7)
3. Lay out the fuselage reinforcements P and D1–D5. Cut four 3×0.5×1000 mm strips and one 3×0.5×500 mm strip according to the cutting layout, checking each piece against the model. Install the reinforcements on both faces and glue them with thin CA. (Fig. 8) (Fig. 9) (Fig. 10) (Fig. 11)

All-moving tailplane

1. Glue the two tailplane bearings into the fuselage with medium CA, observing their orientation. Separate the tube holders and glue them into the two tailplane halves. (Fig. 12) (Fig. 13) (Fig. 14) (Fig. 15)
2. Trial-fit the supplied 330mm carbon tube through the tailplane and fuselage bearings. Separate the elevator horn parts a and b; retain b for the servo arm. Fit a on the tube, pointing downwards. Do not glue it yet. (Fig. 16) (Fig. 17) (Fig. 18)
3. Align the two tailplane halves, leaving a 0.5–1 mm gap at each fuselage bearing. Glue the tube only into the tailplane halves with medium CA. Keep glue out of the fuselage bearings so the assembly rotates freely. (Fig. 19) (Fig. 20)

Nose and lower fuselage

1. Cut the 3×1×1000 mm carbon strip into four 210mm pieces. Glue the undercarriage bolt holders together in pairs with their grooves aligned, then glue them into the fuselage with medium CA. (Fig. 21) (Fig. 22) (Fig. 23)
2. Glue the plywood firewall into the nose with medium CA. Fit the four carbon reinforcements, two above and two below, and secure them with thin CA. Roughen the fibreglass undercarriage plate and glue it to the underside, aligning its holes with the bolt holders. (Fig. 24) (Fig. 25) (Fig. 26) (Fig. 27)
3. Glue the canopy profile to the vertical fuselage. Cut along the illustrated line through the connecting tabs to separate the lower part c from the upper part d. Glue c to the underside of the horizontal fuselage, keeping the joint square. Retain d for later. (Fig. 28) (Fig. 29) (Fig. 30)

Aileron servos and linkages

1. Separate the servo-arm extensions e and aileron horns f. Centre both aileron servos electrically, then fit their arms and extensions as mirror-image assemblies. Cut the lead channels 4 mm deep and trial-fit the servos without glue. (Fig. 31) (Fig. 32) (Fig. 33) (Fig. 34)
2. Align each extension with the 1:1 linkage template. Tack it to the servo arm with thin CA, drill the illustrated retaining hole Ø1.5 mm, fit the retaining screw from the back and trim its projecting end flush. Fix the servos with hot-melt adhesive and route their leads in the slots. (Fig. 36) (Fig. 37) (Fig. 38) (Fig. 39) (Fig. 40) (Fig. 41)
3. Glue the aileron horns into their slots with medium CA. Cut the supplied M2 screws to make 28mm threaded rods and fit a clevis at each end. Adjust each linkage to 54 mm between clevis-pin centres, check against the template and secure both clevises with their pins. (Fig. 42) (Fig. 43) (Fig. 44) (Fig. 45) (Fig. 46)

Main undercarriage

1. Drill the wheel-axle holes in the carbon undercarriage to Ø3.0 mm. Position the undercarriage over the lower fuselage and secure it with the two brackets, four M3×30 mm screws and four large M3 washers. (Fig. 47) (Fig. 48) (Fig. 49) (Fig. 50)
2. Drill the wheel hubs to Ø3.0 mm. Assemble each wheel on an M3×16 mm axle screw with a small washer and nut. Roughen the three bonding tabs on each wheel-pant holder, fit the holder and secure the assembly to the undercarriage with the remaining small washer and M3 cap nut. Glue the EPP wheel pants to the holders with medium CA. Check that both wheels rotate freely. (Fig. 51) (Fig. 52) (Fig. 53) (Fig. 54) (Fig. 55)

Elevator and rudder controls

1. Centre the elevator servo, fit extension b and align it with the elevator template. Secure the extension with thin CA and a retaining screw through the Ø1.5mm hole, trimming the screw flush as for the ailerons. Fix the servo with hot-melt adhesive after checking its position. (Fig. 56) (Fig. 57) (Fig. 58) (Fig. 59) (Fig. 60)
2. Shape the ends of the Ø1.8×100 mm elevator pushrod and fit its fixed clevis and M2 threaded coupler with thin CA. Screw the adjustable clevis onto the coupler. The drawing gives 130 mm between pin centres and 98 mm between the indicated fitting faces; these are assembly dimensions, not carbon-rod cutting lengths. Set the tailplane level with the horizontal fuselage, secure the clevis pins and only then glue horn a to the tube with medium CA. Keep the bearings free of adhesive. (Fig. 61) (Fig. 62) (Fig. 63) (Fig. 64)
3. Prepare the rudder servo arm using the same method and the rudder template. Assemble the Ø1.8×125 mm carbon pushrod with its clevises and M2 threaded coupler. The drawing gives 144 mm between pin centres and 103 mm between the indicated fitting faces. Secure the fixed fittings with thin CA; leave the threaded clevis adjustable. (Fig. 65) (Fig. 66) (Fig. 67)

Upper fuselage, tailwheel and power system

1. Glue upper fuselage part d into place with medium CA, then fit the fin and rudder assembly. Check alignment and free movement of the rudder. (Fig. 68) (Fig. 69)
2. Separate the tailwheel-bracket parts. Drill the wheel hub and the illustrated clearance hole to Ø2.0 mm, and the opposite bracket hole to Ø1.6 mm. Fit the wheel with the M2×10 mm axle screw, fold and glue the bracket sides with medium CA, and check that the wheel rotates freely. (Fig. 70) (Fig. 71) (Fig. 72) (Fig. 73) (Fig. 74)
3. Attach the tailwheel bracket to its mounting plate with the M2×5 mm pivot screw. Secure only the projecting screw end with medium CA and accelerator as illustrated; keep the pivot free. Glue the mounting plate to the fuselage with medium CA. (Fig. 75) (Fig. 76) (Fig. 77)
4. Glue the rudder horn into its slot with medium CA, connect the pushrod and secure the clevis pins. Set the rudder to neutral with the servo centred. (Fig. 78) (Fig. 79)
5. Secure the selected motor to the firewall and install the ESC and receiver according to their instructions. Route and secure all leads clear of the motor and linkages, and provide cooling for the ESC. Although the drawing shows the completed propeller assembly, leave the propeller off until the radio and motor checks are complete. (Fig. 80)

Assembly drawings

Pre-flight preparation

Radio and control checks

1. Connect the servos and ESC to the receiver according to the radio instructions. Check that the BEC voltage is suitable for the receiver and all four servos. Use the linkage templates to check neutral positions and linkage geometry.
2. With the propeller removed, switch on the transmitter with the throttle at minimum, centre the other controls and trims, and connect the flight battery. Check every control direction and adjust the linkages to neutral.
3. Set the recommended throws. Moving a linkage closer to the servo shaft or farther from the control-surface pivot reduces the throw; the reverse increases it. Check for free movement throughout the selected travel and secure every clevis pin and servo-arm screw.

Control throws

Control surface	Low rate		High rate
	Throw	Expo	Throw	Expo
Ailerons	±35°	45 %	±50° or more	45 %
Elevator	±30°	45 %	±50° or more	45 %
Rudder	±35°	50 %	±47°	50 %

Use low rates for the first flights and classic aerobatics. High rates are intended for experienced pilots flying 3D aerobatics. Set the expo direction according to the transmitter instructions so response is softer around neutral.

Motor rotation

With the propeller removed, check motor rotation. If necessary, disconnect the flight battery before swapping any two of the three motor wires, or change rotation using the ESC programming procedure. Once the radio and motor settings are correct, disconnect the battery and fit the propeller according to the motor and propeller instructions.

Centre of gravity

Secure the flight battery to the side of the lower vertical fuselage with hook-and-loop tape. With the model complete and ready to fly, adjust the battery position to obtain a CG 260 mm behind the front edge of the EPP nose, measured along the fuselage as shown. The reference is the foam nose, ahead of the firewall. (Fig. 81)

Attention

Use the specified CG for the first flight. An incorrect CG can make the model unstable or uncontrollable. The original manual permits later adjustment to suit an experienced pilot, but gives no approved adjustment range.

Range check

Fully charge the flight battery and transmitter batteries. Perform the radio manufacturer’s range check with the motor stopped and running at full throttle, securing the model safely and keeping everyone clear of the propeller. The range must remain almost unchanged; a reduction greater than 10 % is unacceptable. Do not fly unless every range and control check passes.

Flying

The model is intended for pilots who have already mastered a trainer with aileron control. Choose calm weather and a clear flying area for the maiden flight. Ask an experienced pilot to inspect the completed model and assist with trimming if needed. Start with low rates and check the model’s behaviour at a safe height before attempting aerobatics.

Appendix

ESC instructions

Follow the instructions for the controller you install (Recommended: KAVAN standard ESCs, KAVAN Plus ESCs or KAVAN PRO SBEC ESCs). Verify the ESC and BEC ratings against the chosen battery and servos before connecting power.

Caution

• Do not install the propeller on the motor when you test the ESC and motor for the first time to verify the correct settings on your radio. Only install your propeller after you have confirmed that the settings on your radio are correct.
• Never use ruptured or punctured battery cells.
• Never use battery packs that are known to overheat.
• Never short circuit battery or motor terminals.
• Always use proper insulation material for cable insulation.
• Always use proper cable connectors.
• Do not exceed the number of cells or servos specified for the ESC.
• Wrong battery polarity will damage the ESC and void the warranty.
• Install the ESC in a suitable location with adequate ventilation for cooling.
• Use only batteries that are supported by the ESC and ensure the correct polarity before connecting.
• Switch your transmitter ON first and ensure the throttle stick is in the minimum position before connecting the battery pack.
• Never switch your transmitter OFF while the battery is connected to your ESC.
• Only connect your battery pack just before flying and do not leave your battery pack connected after flying.
• Handle your model with extreme care once the battery pack is connected and keep away from the propeller at all times. Never stand in-line or directly in front of any rotating parts.
• Do not immerse the ESC under water, do not allow it to get wet while powered up.
• Always fly at a designated flying site and follow the rules and guidelines set by your modeller’s club.

Repairs and maintenance

• Please perform the range check in the beginning of each flying session.
• Before every take off please check the correct control surface movement.
• After every landing check the plane for any damage, loose clevises or push rods, bent undercarriage, damaged propeller etc. Do not fly again until the damage is repaired.

Despite the toughness of EPP foam, the Savage Max V2 can be damaged. Repair minor damage with CA adhesive or clear adhesive tape. Replace seriously damaged parts with suitable original spares obtained through a KAVAN dealer.

After a crash or hard landing, immediately move the throttle to minimum to prevent damage to the ESC.

Failure to lower the throttle stick and trim to the lowest possible positions in the event of a crash could result in damage to the ESC, which may require replacement of the ESC.

Note

Crash damage is not covered under warranty.
