hi chaps,
After having a quick 10 minutes play with a hubsan 4X wotsit I found myself on ebay buying quad stuff. So ive got a KK2 on the way and esc etc. I already have a 9X for my trex 450 airwolf model. I need a new rx for this quad thing, but I see there are telemetry thingies. what do these do? do I need one? which rx is suitable for the standard turnigy transmitter module? I've got open TX firmware on the 9X. so how confused am I now?
