Twister 400 Sport V2 Instruction Manual
mode 1 (throttle right) transmitter
▼
The right stick controls throttle (climb or descend) and cyclic roll control to crab
the helicopter left or right.
▼
The left stick operates the tail rotor controls yaw (left or right) and cyclic fore/aft
controls which move the helicopter forwards/back.
transmitter stick movements
Helicopters require relatively small control inputs of relatively short duration.
Do not move the sticks to extreme positions! A delicate touch is required on the
sticks. The sticks should be allowed to return to neutral almost immediately after a
control input is made. If you watch an experienced pilot hovering his helicopter, you
will see that his transmitter sticks hardly move. This is the goal you will be working
towards in this guide.
Height control
A helicopter’s rotating wings - the rotor blades, generate lift, in the same way that a
propeller generates thrust. The lift generated by the main rotor blades increases as
rotor speed rises causing the helicopter to climb. Conversely as the main rotor speed
is reduced, the helicopter descends.
This method of helicopter height control is called ‘fixed pitch’.
Height is managed using the throttle stick of your transmitter.
Push forward to climb, pull back to descend.
yaw control
Yaw control is achieved by altering the speed of the tail rotor causing rotation to left
or right about the main rotor shaft.
When a helicopter is in the hover it can be yawed left or right.
Push the rudder stick left to yaw the nose of the helicopter to the left and push to the
right to yaw the nose right.
Your Twister 400 Sport V2 helicopter is fitted with a micro piezo gyro and electronic
mixing system which automatically helps stabilise the tail making for much easier
flight.
Steering control - fore and aft cyclic
When hovering, a brief forward push on the cyclic control stick will tilt the rotor disc
forward causing the helicopter to move off in that direction. Pull the stick back gently
to stop it. If you pull the stick back further, you start flying backwards.
Steering control - roll cyclic
When hovering, a brief right control stick movement will roll the rotor disc to the right
and the helicopter will start moving to the right. By briefly moving the stick to the left
any right drift or movement will be arrested or reduced.
mastering the hover
Both experienced model and full-size helicopter pilots in the hover will gently ‘nudge’
the cyclic controls automatically in order to keep their helicopter in one spot and
prevent it from moving away from that spot.
A large part of the initial learning phase in helicopter flight is about mastering the
cyclic controls and learning to hover. Control commands will become ‘instinctive’
when you have ‘mastered’ the hover.
