!REDUCED! 40.00 - Walkera 2601/Helimax TX 624 - 6Ch. 2.4Ghz Programmable TX - NIB

HELIMAX TX624 - aka - WALKERA 2601 2.4Ghz TX

For Sale - Brand new & tested only to make sure its operational, send me a PM if interested.


Here is a link; http://www3.towerhobbies.com/cgi-bin...?&I=LXWRH4&P=7


This transmitter will bind to ; NOVUS CP, WALKERA 4G3, WALKERA 4G6, and basically any 6 channel WALKERA reciever/helicopter in 2601 mode. So if you've been thinking about buying a Walkera/Novus heli but dont have a Walkera TX then this is the least expensive way to go as opposed to buying the 2801 pro computer radio ~ $150.00 new.... The helimax brand is actually walkera but helimax is a domestic company and I have found the Helimax quality to be superior to Walkera (QC).


$50.00 Shipped anywhere in continental USA, Actual item is pictured.


Also this TX is Fully Programmable!! check this link for Walkera's website ; http://www.walkera.com/en1/particular.jsp?pn=WK-2601 Comes with SIM Cable for RF 4/5, FMS, etc... all you need is a USB dongle to connect to PC. See below post for instructions on how to program this 2.4GHZ Transmitter.

Through a series of dip switches in the back and VR pots on the front.

Throttle curves, pitch curves, servo extents, gyro, revo mix, norm, Idleup, etc.. all programmable with this TX.

If you have any other questions let me know.....

This is taken directly from the included manual;

Switch Function Default
1 Elevator Reversing Switch Off
2 Aileron Reversing Switch Off
3 Throttle Reversing Switch Off
4 Rudder Reversing Switch On
6 Pitch Reversing Switch On
8 Revolution Mixing Reversing Switch On
9 CCPM Mixing / Normal Mixing On
11 Pitch Curve Adjustment Off
5 Gear Reversing Switch Off
12 Gyro Gain and Revolution Mixing Off
10 Throttle Position and Servo Exponential Adjustment Off
7 CCPM Elevator Reversing Switch Off

Transmitter Settings

Throttle Position and Servo Exponential Adjustment
Remove the switch cover from the back of the transmitter. With the transmitter
turned off and the flight battery disconnected from the helicopter, set both
the V1 and V2 dials to 0. Set the Flight Mode Switch to NORM. Set switch
10 to On and turn the transmitter on to enable Throttle Curve and Servo

Exponential Adjustment.
The V1 dial is used to set the throttle % at mid stick for either normal flight
mode or idle up flight mode. Set the flight mode switch to the flight mode you
would like to adjust. Turn the dial towards “-100” to reduce the throttle position
at mid stick. Turn the dial towards “+100” to increase the throttle at mid stick.
The recommended throttle position for normal flight mode is +15 and the
recommended throttle position for idle up flight mode is +30.
The servo exponential is set by using the V2 dial. Set the dial to 0 for linear
travel, use +1 to +100 to decrease the sensitivity of the cyclic controls and -1
to -100 to increase the sensitivity of the cyclic controls. The factory setting is 0
which provides a linear feel. If you feel the controls are overly sensitive then we
would recommend trying +40.
When you are done making adjustments, set switch 10 to Off.

Pitch Curve Adjustment
Remove the switch cover from the back of the transmitter. With the transmitter
turned off and the flight battery disconnected from the helicopter, set both the
V1 and V2 dials to 0. Set the Flight Mode Switch to NORM. Set switch 11 to On
and turn the transmitter on to enable Pitch Curve Adjustment.
The V1 dial is used to adjust NORM flight mode hovering pitch. Turn V1 towards
+100 to add more pitch at mid stick. Turn V1 towards -100 to decrease pitch at
mid stick. Adding more pitch will decrease the hovering head speed. Less pitch
will increase the hovering head speed. The V2 dial is used to adjust the maximum
pitch range. If you feel the model needs less pitch at full positive or negative
collective then turn the dial towards -100. If you feel the model needs more
pitch at full positive or negative collective then turn the dial towards +100. Too
much pitch may overpower the tail rotor’s ability to maintain heading. It is best
to make small adjustments and perform a test flights between adjustments.
When you are done making adjustments, set switch 11 to Off.


Gyro gain Adjustment
Remove the switch cover from the back of the transmitter. With the transmitter
turned off and the flight battery disconnected from the helicopter, set both the
V1 and V2 dials to 0. Set switch 12 to On and turn the transmitter on to enable
Gyro gain and Revolution Mixing Adjustment.
The V1 dial is used to set the gyro gain. Simply set the gain by turning the dial
towards “+100”. The recommended starting gain is +80. If you notice that the
tail is slow drifting then a higher gain value should be used. If you notice that the
tail rotor quickly oscillates back and forth then lowering the gain value should
help.

Revo Mixing Adjustment
The revolution mixing is set by using the V2 dial. Set the dial to 0, use +1 to
+100 to set the amount of revolution mixing. The factory setting is +30. If you
notice the nose of the helicopter is rotating to the left during a climb out then
simply increase the revolution mixing. If you notice the nose of the helicopter
rotating to the right during a climb out then the revolution mixing is too high and
simply decrease the value.
When you are done making adjustments, set switch 12 to Off.
