Specifications

Technical Data / Specification

• Length: 652mm
• Wing Span: 717mm
• Flying Weight: approx. 330g

Power System

The model is powered by a brushless outrunner motor and a ducted fan, both factory-installed on the PNP version. The motor is connected to the electronic speed controller (ESC), which is factory calibrated on the PNP version. You only need to charge the Li-Po battery according to the safety instructions and connect the battery to the ESC.

The ESC is located in the fuselage in front of the impeller.

To check the model's operating systems, first set the control surface servos to neutral by setting the trims to center and leaving the throttle stick and trim to the lowest position.

When you wish to fly the model, always ensure the transmitter is "ON". Move the throttle stick to the "OFF" position. Then connect the battery to the electronic speed controller.

To power down, proceed in reverse order: disconnect the battery from the ESC first, and then switch off the transmitter.

Radio Control System

To fly the Viper, you will need a radio control system with at least four channels. 2.4GHz radio systems are recommended, similar to the unit included with our PNP version.

The servos for the ailerons and the elevators are factory-installed.

The power for the receiver is drawn from the ESC's integral BEC system.

Glued Joints

Foam-safe epoxy is recommended and available from most reputable model retail shops. Trial-fit all parts “dry” before applying glue. Follow the recommended curing time suggested by the glue manufacturer. Allow the glue to fully cure (harden) to the point where the joint can be placed under stress.

Pre-Flight Checks and Tuning

Charging the Battery

Fig. 30: Charge the battery, and connect the white charge lead and adapter lead matching your charger (Charger and battery are not included).

Transmitter Setup

Fig. 31: Switch the transmitter on and move the throttle stick to the "OFF" position (Diagram shows right joystick as throttle control stick, which is on MODEL 1).

Checking Ailerons and Elevators

Fig. 32 & 33: Check that the control surfaces respond to the appropriate movements of the transmitter joysticks. If not, swap over the servo lead at the receiver.

Check the neutral position of the control surfaces; you may need to screw the clevises in or out to correct any discrepancy.

Stand behind the model.

Check the direction of rotation of the servos:

• Move the aileron stick to the right (a), and the right aileron (a) must rise up, the left aileron (b) fall down.
• Pull the elevator stick back towards you (c), and the trailing edge of both elevators should rise (c).
• If either function works in the wrong way, correct it using your transmitter's servo reverse switch for that channel.

Checking the Power System

Fig. 34: Hold the model securely.

Remove any loose objects such as cloths, tools, etc., from the area in front of the model, as they could easily be sucked into the ducted fan.

Open the throttle (stick forward): the motor should now run, and you should feel a strong airflow rushing out from the tail end of the model.

Move the throttle stick back to the "OFF" position.

Disconnect the battery from the electronic speed controller and then switch the transmitter off.

Checking the Model's Balance (CG)

Fig. 35: Place the battery in its compartment without connecting. Mark the Centre of Gravity (CG) on both sides of the fuselage; the position is shown in the photo.

Support the model at the marked points and allow it to hang freely. When correctly balanced, the airplane will remain horizontal with the nose slightly down.

If necessary, adjust the position of the flight battery to achieve the correct CG.

Mark the battery location in the fuselage so that you can be sure of positioning it correctly after recharging.

Pack scrap pieces of foam around the battery in its final position, otherwise there is a danger of it shifting in flight and altering the model's balance.

Charge the flight battery, and the model is ready for flight.

Access to Ducted Fan Unit and ESC

Fig. 36: The ducted fan unit is accessible from underneath if you need to carry out maintenance work or repairs.

Ensure that the wire colors match correctly. If the motor direction is wrong, swap two poles between the motor and ESC. The direction of rotation will change.

Test Flying Notes

Please read the sections entitled "Routine pre-flight checks" and "Flying the model" in the Safety Notes before attempting to fly the Viper for the first time.

For the first flight, you should wait for a relatively calm day with no more than a gentle breeze.

A good flying site is a large, flat, open field; well away from trees, fences, high-tension overhead cables, and other potentially dangerous obstacles.

Carry out a complete check of the working systems.

We recommend that you ask an experienced modeler to help you initially, to give the model a fairly powerful hand-launch.

The model must be launched directly into any existing wind.

Switch the motor on and launch the airplane strongly into the wind, with the fuselage and wings leveled.

Allow the Viper to fly straight and level initially; don't try to turn it when it is close to the ground.

Adjust the trims if necessary so that the model settles into a steady climb.

Check the model's response to control commands from the transmitter.

You may need to increase or reduce the control surface travels once the model is back on the ground.

Take the airplane up to a safe height and check its stalling speed.

Keep the speed well up on the landing approach to avoid stalling.

If you had to move the trims during the flight, correct the mechanical linkages before flying again. This allows you to re-center the trims, so that full trim travel is available for subsequent flights.

Tuning Parameters (Example Settings)

These values are for orientation and should be adjusted to your preferences. The maneuverability can also be increased or decreased by adjusting the linkage further in or out on the control horn of the respective control surface.

• 1: Dual Rate* Aileron / Elevator 75% / Expo** 45% (gentle flight)
• 2: Dual Rate* Aileron / Elevator 85% / Expo** 45% (dynamic aerobatics)*
• 3: Dual Rate* Aileron / Elevator 100% / Expo** 45% (high maneuverability)*

* Dual Rate = Electronic servo travel limitation (controls the maximum servo deflections).

** Expo = The servo's control curve is flatter around the center position (e.g., a higher Expo value makes the model more docile around center, a lower Expo value makes the model more agile).

After making changes to the model (linkage adjustments), the model must be trimmed again in flight.
