ATTENTION ALL FUTUA FAST OWNERS. If you don't already know you can have a bad TX and shoot down planes. I have a Futua Fast 6 channel TX and was flying my plane at our park and watched my plane start to fly itself. Then it crashed into the ground. I picked up the pieces and went back to the pit to find out what i did wrong..... As i was moving my controls to see what wasn't working, the guy Four tables over said his planes was working by itself. Come to find out that i was in control of his plane as well as mine.. Then he started moving his controls and started moving my plane..I had another plane in my truck and brought it out and the same thing happen to it. We took our radios to the local hobby shop. There is a RX that Futua sent them to test if the radios are bad. Well after being tested they both were bad.. So PLEASE HAVE YOUR RADIOS CHECKED OUT AT YOU LOCAL HOBBY SHOP BEFORE YOU GO FLYING AGAIN..
