I have a 50 Mz futaba T6XAs. (50 Mz is the ham band.) I have had this radio for about 5 years. I have been running this radio on on 3 planes.. the book said that I should have about 20 to 30 paces on the range checks. I have been having alot the trouble with the 3 plane not geting more the 15 paces when the engine was running... I thought it was the Rx in the 3ed plane. So I swopped it out with plane 2. The same thing... Worked on it all day. So I ternd on all 3 planes at the same time and did a range check.. all 3 would start to glitch at the same time. At about 20 paces. but with the one plane it would glich much sooner when the engine was running. but I will have to get to that later.. I have a 2nd transmitter on the same channel so i swopped the batteries and did the same test with the 3 planes on, and got 20 Paces.

What I am asking is.. On this Futaba T6XAs is 20 paces ok.. The guys at the field said that was not good, and I need to fix it. But with 3 Rx and 2 Tx and got the same thing.. I just do not know.

Help out plz

thanks
Paul
