Hi,

I have Rcb7x, i fly Electric helis and may be planes in future,
i just need the suggestion for buying a TX from spektrum, JR etc
budget is around 12k.

i am thinking about 9xr, dx6i or JR xg6

Well You can go with Jr or spectrum in this budget .
XG6 and Dx6i are in same price range. But XG6 looks more cool and got telemetry also .
Jr is now on DMSS only so costly Rx. (2 clones cheap rx introduced but no good reviews yet )
Spectrum are on Dsm2 so more preferred .(orange rx , in budget )

Also u can get FrSky Taranis (16ch).
So many features you can ever imagine . Do check it .
And it is in your budget .Also u can use 2 modules in it at once, voice alert , telemetry etc.

where can i get Frsky accst taranis in india

Well right now you won't find Taranis in India. Even its out of stock in all foreign websites .
