Introduction

Sharing the same revolutionary flight stabilisation system as Twister’s highly acclaimed 2020 Ninja 250 – not to mention its celebrated novice and advanced flight modes, auto take-off and land functionality, and altitude hold feature – the new Twister BO-105 is everything the Ninja was, and more ! Not only does the ‘105 make supreme use of a highly efficient duration-optimised four blade rotor head to deliver an outstanding 15-minute flight duration, it offers the valuable peace of mind that can only be experienced with damage-limiting auto shutdown programming. And as if that’s not enough to tempt you, all this ground-breaking technology is cloaked in a beautifully-detailed 1:48-scale BO-105 body. To cut a long story short, it looks fantastic, it’s rock-solid and easy to fly
and, to cap it all, it’s got Ninja durability at its core.
AGE RECOMMENDATION: NOT FOR CHILDREN UNDER 14 YEARS. THIS IS NOT A TOY

Transmitter switch identificaton

Transmitter mode change
When first switched ON the transmitter will always automatically select Mode 2. If you want to select Mode 1 you must follow the procedure noted below every time you power up the transmitter. .

1. Connect the battery to the helicopter and place it on a level surface. The LED on the helicopter will blink slowly.
2. Blip the Mode switch down and hold it in the lower position.
3. Switch the transmitter ON with the Mode switch still held in position and wait for an audible tone and flashing LED on the transmitter. The helicopter LED will now flash at a higher rate. At this point you can release your hold on the Mode switch.
4. Advance the right stick (throttle Mode 1) to 100%. A short audible tone will be emitted and the LED on the transmitter will start to flash faster. Now reduce the throttle to 0% which in turn will be met by a long audible tone, whereupon the LED on the transmitter will illuminate solid red.
5. With Mode 1 now selected the LED on the helicopter will illuminate solid red. You are now ready to fly in Mode 1.

Please note that if you’re a Mode 1 flyer the mode change procedure has to be performed every time the transmitter is switched ON.

Co-Pilot technology
The BO-105 two tier Co-Pilot technology makes it a very clever piece of kit. The first tier of the Co-Pilot software is a flight aid that constantly assists you when the helicopter is airborne and remains active in both Novice and Advanced flight modes (see below).  This includes 6-axis gyro stabilisation to smooth the model’s flight pattern through manoeuvres and to dampen the effect of turbulence. It also includes altitude hold functionality that works to maintain a constant height through all manoeuvres while the throttle remains untouched.
The second tier of the Co-Pilot software (Co-Pilot Assist, activated using Button A) offers Auto Take-off, Auto Land and Emergency Shutdown options. For a full explanation of this see ‘Button A — Co-Pilot Assist’ below.
Button A — Co-Pilot Assist
Button A operates the Co-Pilot function and has three different uses to aid you in your flying experience. With the helicopter and transmitter switched ON and ready for flight the Co-Pilot button works as follows:

1. Press the button momentarily for Auto Take-off. This will start the rotor blades of the helicopter and will automatically increase the RPM to the point where the helicopter will take-off. When it reaches a height of around 1.5m it will stop climbing and remain in the hover. Note that you will still have complete control over the helicopter during its ascent, however if you move the throttle stick it will instantly break out of Auto Take-off mode.
2. Making sure that the helicopter is within 10 feet of the ground, press Button A momentarily for Auto Landing. This has the reverse effect of Auto Take-off, i.e. as soon as the helicopter has landed the motor will shut down. During the descent you will still have full control of the helicopter but if you touch the throttle you will instantly break out of the Auto Landing sequence.
3. Press and hold Button A for 3 seconds to activate the emergency shutdown function. If you lose control of the helicopter this lets you abandon the flight by shutting down the rotor completely, allowing the helicopter to fall to the ground. In most cases the durability of the B0-105 will allow damage-free crash landing, however always check the helicopter for damage when this function has been used.

Button B – Flight Modes
Button B operates the Flight Mode function, of which there are two options: Novice and Advanced. Novice Mode offers full control of the helicopter but employs reduced control movements to soften the helicopter’s response. Advanced Mode offers full control of the helicopter with full control movement, making the BO-105 far more reactive to stick input.

1. Momentarily press the button to switch to Advanced Flight Mode. This is highlighted by two audible beeps.
2. Momentarily press the button again to switch from Advanced Flight Mode back to Novice Flight Mode. This is highlighted by a single audible beep.

Note: Your B0-105 will default to Novice Mode whenever the transmitter is switched ON.
Power switch
Before powering up the transmitter make sure you have inserted 4 AA batteries (not included).
To switch it ON, move the Power Switch to the up (ON) position. Note: Always plug the battery into the helicopter before switching the transmitter ON. This allows the transmitter to find the helicopter’s signal.
Power indicator
The LED power indicator keeps you informed of the battery power in the transmitter.
If the batteries begin to get low the LED will start to flash warning you that the batteries need replacing. This is not to be confused with the power LED acting as a status indicator during some of the power up procedures, as covered here in ‘Transmitter mode change’.

Fight operation steps

Pre-flight Inspections
Before flight it is your responsibility to ensure you have inspected your B0-105 for any damage that might have occured during previous flights and that it is safe to fly again. We recommend a safe 2m distance when flying.
Preparing for take-off

1. Slot the battery into the helicopter. Press and hold the power button until all Blue LED’s illuminate and the white LED on the front of the helicopter slowly flashes, then place on a level flat surface.
2. Switch on the transmitter and wait for an audible tone. The LED on the front of the tranmitter will start to flash slowly and at the same time the LED on the helicopter will start to flash rapidly. Advance the left stick (throttle) to 100%. A short audible tone will be emitted and the LED on the transmitter will start to flash rapidly. Now reduce the throttle to 0% which in turn will be met by a long audible tone and the LED on the transmitter and helicopter will be perminantly on.
   This procedure will arm the helicopter and is now ready for take-off.

Take-off
The helicopter has two options for take-off.

1. Press Button A (Co-Pilot) momentarily for Auto Take-off. This will start the rotor blades of the helicopter and will automatically increase the RPM to the point where the helicopter will take-off. When it reaches a height of around 1.5m it will stop and remain in a hover. During the ascent you will still have full control over the helicopter but if you move the throttle stick it will break out of the Co-Pilot Auto Take-off mode.
2. The second option for taking off is without a Co-Pilot assist. Move both sticks to the bottom, outermost corners. This will start the helicopter motor and allow you to increase the RPM as needed for a fully controlled take-off. We advise this method only for intermediate and advanced pilots .

Flying
Referring to the section entitled ‘stick controls’ use all your flight controls to guide your B0-105 around your flying area. If you’ve not flown a model before this will take some practice.
The helicopter pre-set Novice Mode will help you through your flight, maintaining a constant height whilst using the 6 axis gyro to keep things steady. For the first flight its good to stay in Novice Mode but as your skill improves you can use the Flight Mode button to switch to Advance Mode which offers more control movement.
Flight trimming
If you find the helicopter drifts in any direction, use the trim buttons described in ‘Trim buttons’ to tune the hover. For best results do this in calm conditions or, better still, indoors.
Gyro calibration
If you feel that trimming the helicopter has not suitably honed any in-flight drift you can land and resolve this by calibrating the gyros. Do note, however, that even in flat-calm conditions all helicopters will drift slightly in the hover due to tiny air movements. This is normal.

1. Set the helicopter on a level surface and power it up ready for flight.
2. Move both sticks to the bottom left corners and hold them in position.
3. You will hear an audible tone from the transmitter and the helicopter will confirm the calibration with the LED changing from constant red to flashing red, then back to constant red. The calibration is now complete.

Low Battery Warning
The B0-105 is equiped with a low battery warning. The LED at the rear of the helicopter and on the bottlom will start to flash when the battery is nearing depletion. This allows about 20 seconds to land before the BO-105 engages its low power battery landing mode to protect the battery. If the helicopter enters low battery mode it will slowly descend until it reaches the ground, whereupon it will shut down.

Landing
The helicopter has two options for landing:

1. Using Button A (Co-Pilot Assist) you must make sure the helicopter is within 10 feet of the ground.
   Press Button A momentarily for Auto Landing. This works in reverse of the Auto Take-off function and, accordingly, as soon as the helicopter lands it will shut down the motor. During the descent you will still have full control of the model but if you touch the throttle you will break out of the auto landing sequence.

2. Using the throttle you can manually land the helicopter by gently reducing height until its’s on the ground. Once on the ground hold the throttle at zero until the motor shuts down.

Once the helicopter is safely landed and the rotors have stopped, press and hold the power button on the battery until all all LED’s are off on the battery and the helicopter.
Now the helicopter is off it is safe to turn the transmitter off.
Its good practice to check your helicopter for any damage that might have occured during flight. If you B0-105 has struck any objects pay particular attention to the rotor blades (main or tail) and replace them if any damage is spotted. The performance and safetyof the helicopter relies, amongst other things, on perfectly balanced damage-free rotor blades.
If the worst happens, dont worry, a full range of spares are available from your local J Perkins Stockist.
