I want to sell my rcb 7x for 1800 with battery and no receiver

hi Shyam Hembram  i like to buy that, but need more details including condition and pics please

As you mentioned you need any type of radio,this will fulfill all your needs.Its more than year old,i have fitted red color backlit,two trinming switches not working,but i had made it work,one toggle switch is broken,can be fixed and range is about 900m,rest works fine,will post pics later
