which one to buy ? which is better?
spektrum dx61 or graupner mz-12

Both are good radio but only problem would be sourcing extra receivers..
Graupner rx is available at rcbazzar.com and spektrum i think nowhere in India...
Better to get 9XR pro with frsky module and at the same amt you'll get more channel, cheap Rx reliable system and hack able for further mods

where can i get 9xr pro

Rcmumbai.com, rcproduct.in, parichay gautham on this forum.

Go for Spektrum Dx6i. Clone Orange receiver are damn cheap. cheaper than Frsky. Its available in ebay stores.
I had 9XR but now having Dx6i. 9XR requires 3S LIPO battery and you have to remove the battery every time for charging. But Dx6i requires only 4AA battery. Binding process also easy compare to Frsky.
