RE: Hanger 9 Ultimate.
You say that you dont have the TX antenna screwed into the TX??? This simply may be your problem. When i turn on my 10X without the antenna in the module gets very hot very quickly. Basically you are transmitting and should have the antenna on the TX. On my range checks i just put the antenna on, lower it to as far is at will go and do my range checks. I have never had a problem like this, and have had many large planes.
I'd say put your antenna in on the TX and do a range check and see what you get, if you can go say 50-80 paces you are fine.
Hope this helps
