Turnigy 9xr is better but you would need a seperate module

The 9XR is just the 9X but with the modifications that were previously needed already built in. For example, the backlight and programming port could be added to the 9X with some effort but the 9XR has them already built in. It also comes with a more powerful firmware (an old version of er9x). The 9XR has a few ergonomic issues like the trainer switch is out of reach. However, it is a good choice if you don't want to tinker much and also you can add a FrSky module for a more reliable radio link. An advantage of FlySky is that it is compatible with a lot of WLToys micros.

I would say that if your budget allows it, go for the FrSky Taranis. It is the best Tx in its class at a great price. If you want to seriously get into the hobby, you could even consider big brand names like JR, Futaba, Spektrum etc.
Otherwise, if you are willing to do a lot of tinkering and fine soldering, you can buy the 9X. Otherwise, go for the 9XR and have peace of mind.

If you increase your budget by 3000 , then i'll suggest you buy the JR XG 6 , its a brilliant 6ch radio (which can do telemetry as well ) plus you get the unbeatable and bulletproof performance of JR . The radio is sold by Rcdhamaka which is the best rc retailer in this country .

What exactly is telemetry and will it be very useful???


Title: Help me decide on a transmitter purchase
Post by: Rcjabalpur on March 01, 2015, 12:53:16 PM
Take telemetry gives vital information about your flight system on your Tx , such as temperature , battery voltage , air speed etc . I use two telemetry modules on my 10j , 1) battery voltage , 2) battery temperature . Its upon you to think as to how critical these data are for you .

Is FLYSKY th9x compatible with telemetry by fitting frsky dtj module.


Title: Help me decide on a transmitter purchase
Post by: SK1701 on March 01, 2015, 01:56:27 PM
Not with modifications involving cutting PCB traces and fine soldering to the microprocessor pins. However, I think you can get RSSI from the module itself which will beep when going out of range.

What is the difference between turnigy 9x and 9xr???


Title: Help me decide on a transmitter purchase
Post by: ppcruise on March 01, 2015, 03:30:45 PM
The 9XR has a backlight for the LCD. It also has some changes to the body. Other than that, no major differences. A stock 9XR might have better firmware but I believe you can flash/update the 9X to the same firmware as well.

Easier way out...  Get a Frsky telemetry display...  It works great with the DJT module

I am also planning to get into RC planes flying hobby, and am contemplating which Controller to buy.
Budget is not so high for the controller but if required I can stretch.

For me, the below are absolute requirement.
- 6+ Channels
- multiple Channel Mixing (not pre-mix)
- Rock Solid Connectivity with the Receiver ( within the range < 1km )
- Good Construction ( durable and not toy type )
- Reliable Software.

Here are few I have listed so far:
Avionic RCB7X - RcBazaar
FS-TH9X 9ch - RcBazaar
Graupner MZ-12 - RcBazaar
JR XG6 - RcDhamaka

My comfortable budget for the controller is 5-6k, but if non of the budget ones are reliable and need to be replaced sooner or later I can stretch upto around 10-12k. And the above are in the Range.

I am looking for a controller which my equipment flying in the air can trust its life with. Reliability and Rocksolid connectivity is my primary concern. So, if I have to push my budget I can wait a month or two and go for the extended budget model, but the extra effort I am investing should justify my requirements.

I am looking for models readily available in India especially in Bangalore..

Thanks,
Sapam

If Reliability and Rock-solid connectivity is my primary concern Go for 9x and upgrade to frsky module ....most of us use the same configuration 


Title: Re: Help me decide on a transmitter purchase
Post by: sapam on April 24, 2015, 11:02:32 AM
@madaquif, thanks a lot for the suggestion. I'll keep your suggested option in my mind.

Also, I would like to compare these two option now ( as both will have telemetry ).

1) FS-TH9X 9ch + FrSky DJT  (btw whats the difference between Turnigy 9XR and FS-TH9X, which is better )
2) JR XG6

Ignoring the extra 3 channels 9X has, how are both compared in terms of support (manufacturer&community) and reliability. And how much will be the price difference with both the systems.

Regards,
Sapam

The 9XR is almost the same as the 9x. The main differences are an LCD backlight, programming port, and ergonomics/cosmetics. These were mods that could be made to the 9x but are already built into the 9XR. The firmware is also superior (an older version of er9x). FrSky is supposed to be an extremely solid radio link but the build quality of the 9X as well as 9XR is inconsistent (more so for the 9X). The FrSky DJT module usually does not fit in the 9X module bay without grinding off some excess plastic. It fits without a problem in the 9XR though. Neither the 9X nor the 9XR support FrSky telemetry without difficult internal mods. However, the 9XR Pro does support telemetry. I do not know much about the JR but it is a big name in radios.

The JR XG6 is Rs.12,799 from RCDhamaka. All you need to add is 4 AA batteries (rechargeable is better)
The 9XR is Rs. 6800 from RCMumbai. The 9x is 6000. The FrSky DJT combo pack is 3800 from RCProduct. However, the supplied receiver is not telemetry capable (V8FR). I got the telemetry capable one on request for 4250 (the D8R Plus receiver). A battery will cost you around Rs.1000 for a LiFe battery (better than a LiPo). The 9XR specific battery is around 1800. The total comes up to 11600-12500, almost as much as the JR.
The 9XR Pro costs 8600 bringing the total around 14000. At that price you should consider the Turnigy i10 and the FrSky Taranis.

I think the 9X[R] would be better choice if you plan to fly multirotors as that is when 9 channels is most useful. For airplanes, 6 channels should be enough.

@SK1701, Thanks a lot for the detailed explanation and I really appreciate the effort.

As for me I am more interested in flying Planes and Gliders. So, 6 channels is more than what I need.
Based on your price estimate, it seems I have two option to choose from:
- 9XR+FrSky DJT (D8R Plus)
- JR XG6

So, how do you compare the two models. I guess I will narrow down to these two models so that I don't stretch my budget any further. Another thing is how much compatible receiver (Rx) cost for both? That will also be considered in my buying decision.

Regards.


Title: Re: Help me decide on a transmitter purchase
Post by: SK1701 on April 25, 2015, 11:39:24 AM
@sapam you are most welcome. I wanted to ask how critical telemetry is for you? The 9XR will not let you see telemetry data on the main screen without mods. If you really need to monitor things like the battery voltage and other such data, then you will need to buy a 9XR Pro or FrSky telemetry display (or do the modifications). You could also make your own telemetry display.
With the 9XR and DJT, you will be able to get only an RSSI (Received Signal Strength Indication) warning. If your model is going out of range, the module will beep.
I have also realised you do not need to buy the D8R since it is an 8 channel receiver. The D4R 4 channel receiver ought to do for planes. It has telemetry too. Perhaps you could contact RCProduct and see if they could get you a DJT module with a D4R receiver. The FrSky receivers range from 1350 (D4R) to 2500 (D8R) and more for the new X series and Long Range receivers (you will need an XJT module for these).
I have the 9XR but I have not flown with it yet. It seems decently comfortable though the trainer switch is out of reach. It has a huge range of features and programmability thanks to the er9x firmware (openTx is an even more powerful firmware option). I will get back to you when I use it to fly.
I don't know about the JR but the receivers are expensive: (4600 for a full range 6 channel receivers) The 4 channel receivers I saw on RCDhamaka are only park flyer range.

Post by: sapam on April 27, 2015, 09:51:09 AM
@SK1701, I really don't have any idea of how muck I'll be needing the telemetry. All I know is unless I buy those telemetry modules for temp/vario/alt etc, all I'll be getting from the receiver and the telemetry transmitter is the RSSI and maybe the voltage in some models. And the sensors are itself expensive if ever I need them.

I would like to learn from your experience if there is really a need for the telemetry. To me it seems a timer is all you need.
I will be flying the plane within the visual flight range ( till where I can see the plane and direct it). So, am not sure if there is a need for the telemetry, it just might be a bling bling gadget for me. You can advice me better on this.

I have more than 15 years of experience flying with Flight Simulators and would want to transit into a real thing with RC.

Other than PNP Model J3 Piper  (which I am planning to start with). I'll also be building various models, scale to customized. Thats the reason I want a controller that I can keep for long to learn and understand it to the core and is highly programmable, and something that wouldn't give up on me for a long time.

If I take telemetry out of the equation, then what models Do i Have to choose from? Reliability, Programmable, various options of receiver are some of the main requirements.

Btw, how is Futaba T6J? It cost around 12500.

Can you provide me more insight?

Thanks and Regards.

Post by: SK1701 on April 27, 2015, 06:58:52 PM
With the stock FrSky telemetry, you get to see uplink and downlink RSSI and the receiver internal voltage. It is simple and cheap to make a voltage sensor for the main LiPo. All you need is a basic voltage divider circuit with 2 resistors and the appropriate connectors. I agree that a timer is good enough for most use cases. For me, I landed every couple of minutes and checked the battery voltage on my early flights. Now I know exactly how long I can fly (following the 80% rule). You could also use a LiPo alarm.
I will be able to get my quad in the air in the next couple of days, I will tell you about my experience with the 9XR then. I have prototyped a DIY telemetry display. Once I miniaturise it I can tell you how useful it is.
I don't know enough about the Futaba to comment.

I think I have a fair idea of the roadmap to my RC hobby.

I would like to start with flying PNP and custom aircrafts and gliders for quite some time.
Later, I am very much interested in venturing into Automated Flights maybe using ArduPilot or (using my Arduino kits). During this stage I'll be needing telemetry, but I think I can use 3DR Radio to transmit the information.

Based on the current requirement, I think I wouldn't be needing the Tx/Rx with telemetry. I might just end up with a controller with many channels. So, Turnigy 9x seems to bit the bill. Is there any other alternative I should also consider?

Until I have the radio based telemetry setup to monitor the battery and other stuffs, I think I can rig up a small circuit to check the voltage and light up a RGB LED light under the fuselage to monitor the Battery  Voltage.

Regards

Please help me decide between these two:

1) FlySky FS-TH9XB
2) Turnigy 9X

Both seem to have version 2 firmware. But FlySky has antenna attached to the TxModule, whereas Turnigy has the antenna attached to the controller and it connects to the module by a wire.

Can anyone spell the difference between the two. I am almost certain that I'll be buying any one of these two.

Please advice.

Regards

By functionality, both are exactly the same. They differ only by looks. Go for the flysky as it is cheap in India.


Title: Re: Help me decide on a transmitter purchase
Post by: SK1701 on April 29, 2015, 11:33:23 AM
The main difference is that the Turnigy 9x has the module antenna wire soldered on to the circuit board. This make it harder to swap out the module. The FlySky allows you to just pop out the module and put in a different one. It is cheaper too as Sooraj said. I would suggest you go for a FrSky module since the stock module may have some range or reliability issues.


Title: Re: Help me decide on a transmitter purchase
Post by: sapam on April 29, 2015, 02:51:27 PM
Thank you Sooraj and SK1701 for the advice and suggestion.
I'll definitely go for the FlySky then.

Is there any store in Bangalore I can get  FlySky FS-TH9XB?

Title: Re: Help me decide on a transmitter purchase
Post by: sapam on April 30, 2015, 08:52:40 AM
@Hobbysea, 9XR seems to be a great product, but after adding the Modules/Receiver/Battery, the cost is almost double of a 9X. And at that cost or a little higher, there are more to choose from, and that makes my decision making tad difficult.

Anything above my initial budget of about 5-7k (for Transmitter) will definitely, delay my buying of the transmitter and Planes for sometime as I have mentioned earlier. Its a not an easy choice to make. But, at the price point, based on the feedback I have received so far FlySky FS-TH9XB and Turnigy 9X v2, seems to fit the bill.

I am still checking out for local hobby store in Bangalore that have these.

Regards.

I went through the manuals and review of most of the controllers and after considering all ifs and buts, it seems I'll go for JR XG6.

The reason for this is.
1) JR is available in Bangalore with 1 year manufacture warranty.
2) Very easy and snappy user interface, according to my opinion.
3) Reliable Radio Link, uses DMSS
4) Top notch build and make.
5) xbus system incase I need to expand to more servos controlled by a channel.
6) Profiles transferable to higher models like XG8 etc.
7) controller looks awesome and different.
8) Seems to have the best ergonomic.
9) Very Crips and detailed LCD screen.
10) Got inherent timer for each model.
11) 20 model memory plus via sdcard.

What I'll be missing with XG6:
1) Only 6 channels. ( for future I will have upgrade path to XG8 and above.)
2) No 3 stage toggle switch (a bit of inconvenience but can make use of the delay to have slow retract of flaps and gears)
3) expensive Rx.

Well as monsoon is on and it will be difficult to find time when I'll be free and it's not raining. It seems I can wait couple of months, save up enough to get JR XG8. And 8 channels seems logical in long term.
