I recently purchased a used Novus cp and need help setting up the radio. What settings should I use? I tried the settings in the manual but it has no lift and keeps going backwards and to the right. Does the switch on the left hand side do anything?

is this a flybar model? I think it's a Walkera 4g3
if it's a CP 125, it's a 4g6.
try settings for the appropriate model.
I don't know them right off hand...sorry

you will want to check it out thoroughly, mechanically before messing with the tx settings.

"No lift, backwards and to the right" are multiple symptoms, not all related to TX settings. Plus, it's used so you can't assume it's in flying condition, without going through everything mechanical first. HeliMax rebadges a number of old Walkera models, so you need to provide more specific identification of the model you have. Then you need to describe the symptoms you listed and the circumstances under which they occur, separately.

It is the Heli-Max Novus CP nano size helicopter with the stock TX624 transmitter. I need the settings because right now all it will do is spin in a circle on the floor. I tried the settings I found for a walkera 4G6. When I try to lift off from the floor it takes off backwards and to the right. If I try to hand launch it has 0 lift and falls to the floor with the factory settings.

THe TX624 is not programmable, so settings are irrelevant. Which direction does it spin in? You may have a bad tail motor or gyro.

"Backwards and to the right" is not a problem with transmitter settings. It's more likely to be partially a swashplate or servo issue. Have you verified the swashplate is level, the servos function correctly and the head components have adequate movement in both directions (up and down)?

The transmitter CAN be programed. With the settings I found the tail motor only works when I give it full left input. All the servos work as they should. I just need to know how many clicks on the knobs I need to make the settings correct so it will work.

Sorry, I can't help you. I've never heard of a transmitter that can be programmed without a screen or PC interface. That looks like a Walkera 4G3 with a 2601 to me, which is not programmable, but maybe somebody else knows. The only thing that comes to mind for the spinning is this is an old obsolete model, so it may have potentiometers on the PCB that need to be adjusted.

What was the tx that was just pre 2801tx? If you can find that, it may yield some help.

I seem to recall a progammable 2.4gHz 6ch tx w/o LCD screen. It did not have multi-model memory, either.

The 2603 immediately preceded the 2801. The 2601 was the first 6 channel 2.4ghz Walkera model. If you go to Helimax website and look for Novus CP nano this is what you get: http://www.helimax-rc.com/helis/novu...-cp/index.html. It sure looks like a 4G3 with a 2601. I have no experience with that transmitter and I can't see how transmitter settings would correct the symptoms described. It's a pretty old model and it was purchased used, so it's probably pretty beat up and worn.

The TX624 transmitter is progammable using dip switches.

Novus CP (Walkera 4g3 Rebranded).
TX624 Transmitter (same as Walkera WK-2601).

TazDude69, no lift sounds like you need to program Pitch Curve Adjustment.
Backwards and to the right sounds like one or more dip switches are not correct.

To program you flip a setup dip switch, adjust the knobs, then flip it back.

RE: Does the switch on the left hand side do anything? That is the gear switch.




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.

thanks Tom!

I have a pretty good memory, it's just a little short
