RC India

This is the review of most Hyped Radio of the year Turnigy 9XR (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=31544)-

Saurab Srivastava (http://www.rcindia.org/profile/?u=199) and I, got it almost together (Some pics are courtesy Saurab).

Some Pluses

Good feel to it,
Neat Handle
Good Bright Display
Cheap

Where is the review............?

Orange LR modules fitted well, rx  binding and connection was no issue, will fly fpv and let you all know further. side by side with 9X, 9XR is shade smaller and lighter (With the module)

Some Minuses

Menu key is sticky

Switches feel cheap

balancer wont fit with tx batt having shorter balancer
with the antenne connected to the module, you wont be able to keep the Tx down, solution is to connect it to the internal antenne, then you wont be able to change the module as often as i intend doing

Too bright a display for night flying

Standard tx stand wont fit, need to diy, then the ergo is lost

Has both the trainer ports,
A word about the case, case is good looking but has some play at the hinge and feels slightly cheaper and not as good as it looks.
hooking up to the PC, will report back on the software issues if any and flying reviews with FRSky, 9X, Orange LRS and Spektrum modules

PS
People who have it are welcome to participate. Who dont watch out this space

has been split to accomodate pics along with the review.  ;D ;D. you were quick to draw  >:D

One could argue if module is included 9X is cheaper, but then you get good gimbals and next gen radio. ideal for FPV fliers, you could hook up your LR module for FPV and change over to normal module for other close vicinity flying

Menu key sucks..though unlike 9x it makes less noise while hitting a key,most of the time I have to press really hard to get any response..

Aww...sir.That case and that side looks so sexy!Be a little less harsh on the radio sir.afterall u save almost 150$ for same features on a futaba!

indeed  ;)

switches are placed at an angle which will require some getting used to, i would advice some mock blind folded reach of the switches before assisgning and flying with them

How much in total did u pay for it
?

103 $ (75$+28$) for the Tx and the case (Shipping Incl)

Have you got the receiver with the orange module ? or you have brought separately. ???

Bought them seperately

Has the 9xr team made any significant changes to the er9x firmware...

 here is the LR EPP FPV flown with 9XR with the LRS module, batt is holding out well, next module to go in will be Spektrum Orange, will report back with the same, soon

here is the thread (http://www.rcindia.org/electric-planes/long-range-epp-first-person-view-flight/)

My 9xR works great with the Fly sky 9ch 2.4 Ghz module ;)
+1 for 9xR. It feels great when you hold a 9xR compared to a turnigy 9x. :D

Me too love the looks...  (:|~ (:|~

Haha yup. Which one do you have?

The basic flysky 6ch one(my first)...  :P

Nice. But it dosnt matter. You are pro enough to make this radio turn better than a 9xR :)

Haaha i am a big big beginner(didnt find any lower positions to select in this forum)  :hatsoff:

Just a word of caution that Mode changes are tricky in 9XR. I bought a mode 1 as that was available at the time thinking it is easy to change to mode 2.
I landed up eventually cutting cables and soldering wires to finally get everything working. I changed then two gimbals.

My advice would be buy the one which you fly with. 9x on the other hand was easy.

9xr mode change is fiddly and involved but not difficult.
I've done it without any hassles.

The gimbals are not full ball bearing i.e only one end of each axis
is supported by a ball bearing.

I'm using mine with a frsky JR module - works well enough.

I find the firmware weird and am planning to flash to the original
9x v2 firmware.

Otherwise - it an okay tx - but I find the 9x has a better feel.

I want to charge the lipo thru the charging jack - any suggestions
on how to do this ?

Please no dire warnings - I'm well aware of the  purported risks
involved.

I was planning to connect the balancer tap to the futaba training
port - and use a custom wiring harness , for charging and
balancing the battery while in  the tx.

Any flaws in the above ?

@saikat, sounds perfectly ok if you can bring out the taps, cant say specifically on the the 9xr (dont have one) but for the 9x I've got a similar setup.  Rarely do I charge the battery outside the Tx, only when I have to physically inspect. The pos neg go to the 12v jack in the correct polarity and the taps go to the balancer port on the charger

didn't expect they'd make the mode change so convoluted.

PS: er9x is like arranged marriage. confusing at the start but then you start enjoying it ;) Don't know if that goes for love marriage too, mine was arranged ;)

Flashed with old 9x v2 firmware

how to get the backlight working ?

anybody ?

saikat, the original firmware never had an option to control the backlight (in fact the hardware never had a backlight). Yes, when one would switch on the Tx, the backlight would come up. That was because the positive supply gets routed to the backlight.

Controlling the brightness/duration of the backlight via the er9x firmware also required small hardware mod (http://blog.pannuhuone.pro/p/turnigy-9x-backlight-mod.html) conecting the backlight to a free pin on the atmega. I might be incorrect but *I've a feeling* Turnigy has now included that as a standard feature in the new transmitter...so the older scheme of things might not work

Another simple possible way would be to route a wire from the +5v to the backlight +ve via a 220 ohm resistor, so when the tx is switched on, the backlight comes up; there will be no control of the brightness/duration via a software menu though. Route it thru a toggle switch, drill a hole and mount the switch

thanks girish - that will do nicely - in fact I will use one one of the existing switch positions - since
I do not plan to be flying any super complicated models

Hey Guys!!
How do I change the subtrims? I am using kk2 and it dosnt show all the values 0 in normal position in the receiver test. Please help me.

It should be on the limits screen.

can you make a tutorial on how to adjust them? if possible plz.. or a short video showing you changing them.. or plz link me to a video. :)

Thanks in advance.

@Girish, I figured it out.
Thanks :)

That's a really nice radio.i'm planning to get one.Any advice,thoughts are welcome.Could anyone point out the merits of using the orange module and of the FrSky module?and what kind of Rx for the orange?also,how badly would range take a hit if i used the internal antenna?thank you all in advance.

how do i assign the pit trim. knob for channel 7 on my radio/receiver?

In the mixer settings, CH7 should be 100% (or whatever weight) and source should be P1/2/3 - whichever pot you wish to assign

okay got it
and what about using the switches as ch6?

What would you want to do. Use it as a flip switch between 0 and 100% of servo signal? I dont have the radio in front but off the top of my head i think the following should work

two mixes to ch 6 as below

ch6 trn 100% full
        !trn 0% full replace

using the trn switch here for illustration
full is source. Might be max on your version of er9x

Are you trying to setup  proportional flaps

no, i am using it on my quad for tuning PID
the switch will save the PID settings and the knob(P1) will change the values..

thankyou for your help sir :) I dont have er9x. i have default firmware

Rahul the firmware on 9xr is er9x rebranded

haha okay
i dint knew.
thanks for the help sir. :)
will let you know further more as i proceed

Sir it came without custom hassles and or you had to pay something to them???

no, i bought it from a local store

From Which Store And the case from local store ? Please tell the price too . :)

got it in march i think from rchobbyaddict
7400 with a battery ;)

Thats Good Do They Keep The Aluminuium Case For that If yes How much?

No they dont even keep the radio now!
i got the last piece ;))
aluminium case isnt available, you can buy it from hk

ok thanks for the information we can also buy the radio from hk i think it is wpc approved or we will have custom hassles ?? :)

no idea, ask others
i never bought a radio

what if i put 2200mah 20c battery in turnigy 9xr instead of 2200mah 1.5c. does it effect the transmitter???

yes obviously it will a higher discharge rate lipo will burn your radio

NO, a higher discharge rate lipo will not burn your radio. U can use 20C or even greater for your radio.

this has been discussed before on our forum

I am sorry was wrong I take my words back

Chintal
To err is.....being human  ;D
And a person who realises his own mistakes is great.  :salute: :bow: {:)} {:)} {:)}

thank u sir,
i am thinking to buy an helicopter belt 250 V3 used. but in good condition in 4.5k ( with all electronic parts Without tx rx). if anyone use this helicopter previously. plz give me your review. how was this. should i go for this.
