What are the differences between the FS-TH9X and FS-TH9XB.
How to choose between the currently avaiable FS-TH9X as some have Module with antenna and others that have antenna on top of tx.
Which is the best one considering a future change to the FrSky DJT telemetry system? can the one with antenna on module use this system?
This is what is available at RCBazaar(With antenna on module):
http://www.rcbazaar.com/products/397-fs-th9x-9ch-24ghz-transmitter-receiver.aspx

And at Hobby partz(Antenna on top):
http://www.hobbypartz.com/79p-th9x-r9b-9channel-radio.html
The one at hobbypartz looks identical to the Turnigy9X available at HobbyKing.

Are there any major differences in hardware between the two?
And which one is the one available at RCBazaar?
Which will be most updated and also suit my needs?
Considering a FrSky module mod and ER9X or Open9X FW mod in the future which 9X is best?
Please help as i am going to buy this. All help is appreciated

In my opinion both are same! only difference is 9x which has separate module which can be removed easily ! 9x which you are seeing at RCB was primarily designed for use with FM module ,which now are obsolete! because every one is using 2.4 Ghz.
9xb has attached 2.4ghz antenna in the place of normal FM antenna ! if you want to change module you need to take out entire module out by desoldering RF wire .something like this


coming to Hardware apart from RF module! rest of them are same!
you can go for any one of them! but comes with stock firmware!If you want ER9X or Th9x you need to burn the code yourself ! ( a bit messy work though ,soldering wires to patch on the board).
i have both the radios (with different brand name Eurgle 9x as TH-9x and Turnigy 9x as TH-9xb),both one are running on Frsky moduule
i have removed RF connection between antenna and module from Turnigy 9x for using Frsky module!

Thank you very much sir,but in the FS-TH9X ic an easily remove module without desoldering or cutting RF wire right? Then i just put in the FRSky module

yeah thats right 

So if i dont want to mess around with the RF coax then i should buy the RCB one? and burn the code myslef of ER9X with ISP header pins?
Thank you for te info sir really appreciate it

Anytime 

RCB one should be better for easy placement and removal of FrSky module then right praveen sir?
The internal one needs some soldering for using FrSky module

i told you

Thanks
just wanted to confirm which has module with antenna for easy swappability
any big knobs that you know of for the BK5 pots on it? the stock ones are too slim for my liking.

i use stock switches and knobs on my 9x.
