Turnigy 9ch Setup

The Turnigy 9x is a very powerful transmitter package for the money, in fact I would bet that it is the best value transmitter on the market.
It is let down in a few areas.
1.     Build quality can be a problem although version 2 is a lot better in this regard.
2.     It doesn’t come with a manual, but you can download one for the Imax-9x which is the same radio.
3.     The programming interface is not intuitive compared to other similar spec’d radios, although this is easily learnt.
4.     The aerial is hardwired to the unit which makes it slightly awkward to remove and use as a sim controller.

A good review and a battery mod can be found at www.rcmodelreviews.com where it gets an excellent review.  Beware of people who bash these radios as they haven’t actually used one and often get name brand blindness. For the non-rich or the modeler on a budget they are the perfect addition to your fleet.
Programming the Turnigy 9x for a Trex 450:

The setup is a little confusing for the Turnigy 9x, couple this to the difficulty of setting up a CCPM heli if you are a beginner and it can make for a frustrating time.

I decided to write this to help anyone who has trouble getting it all sorted. I am assuming that you know the basic menus and how to get around them, have a play first and get familiar first before jumping right in.

All Menu items are shown in bold for easy reference

1.     Setup a new model memory, select HELI then click the menu button to select.
(quick clicks of the menu button select, long ones reset the amount).
2.     After selecting HELI it gives you the heli menu, choose Heli 3-1 which Is for 120 degree CCPM, this is the system of three servos that the TRex and many others use.
3.     Once selected exit back to the System setting menu and then check that under the STICK SET heading that mode 2 is enabled.
4.     Now exit back out and now go into FUNC SETTING menus.
5.     To work out which servo goes where is easy, elevator is channel 1 on the receiver, this is the servo at the rear of heli just behind the main rotor shaft.  The other two servos plug into channel 6 (pitch) and channel 2 is the aileron doesn’t matter which way round these two are. Your gyro goes in channel 4 and the gyro adjustment goes in channel 5, esc goes into channel 3.
6.     Go to THR HOLD in the function setting menu, at the state option change INH (inhibit) to ACT (active) a line of text will appear above saying THRO CUT (OFF) flick the switch at the top left back of the unit, this will turn it to (ON). Throttle hold is for safety it allows the pitch etc to be checked without the motor turning on. Also useful for general safety at the field.
7.     Back to FUNC SETTING menu. Under AUX-CH leave all as Null as you don’t need to enable any other channels at this stage.
8.     SWASHAFR  is the amount of mix each channel gives in 120 degree ccpm.  If you have trouble reaching 10-11 degrees positive and negative pitch you can change the amount of pitch in here to a higher value If required, your pitch curves then set the limits.
9.     Back to FUNC SETTING menu. On the second function setting page you need to go into GYROSENS and turn it on, switch from INH to ACT. Scroll to model and change to GY if you have a GY401 futaba or clone, then scroll up to the UPRATE and DNRATE, if you change from NOR 100 by clicking the – button you will get to 0 and then back up to 100 but you’ll notice that NOR changes to AVC, this is your gain for AVCS or heading hold mode.  Now the switch is the front top right shoulder switch, this can be used to flick between two gain settings, or two modes of your gyro depending how you set it up.
Mine is setup for GY mode, UPRATE AVC 75%, DNRATE NOR 60% which lets me switch between heading hold and rate mode easily.

10.  Once the above are setup you can move onto your pitch and throttle curves, these are easy enough to setup and for detailed information on these please refer to Finless Bob Whites videos as he explains it well.
Both can be found in the FUNC SETTINGS menus.

11. SUBTRIM is also handy to get your ccpm servos all setup level, but you will learn this from Finless’ videos anyway.

12. ENDPOINTS are also useful to get rid of CCPM interations, again please refer Finless’  videos for more.

That’s it, easy as but its also easy to pick the wrong setting if you don’t know what you are doing and this can lead you astray!
