Hello
I have problems with signal glitches in my evelator channel (2)
I had a plane where somehow the elevator channel started having signal glitches, the elevator flozen and when airborn I had not elevator and crashed the plane with total loss.
For the new plane I changed everythinf related to radio: New Receiver (R168DF), New servo (hitec high torque), New RX Crystal (72 MHZ channel 21) , new Switch harness, new battery.
I also ntocied that I had a carbon fiber pusrodin the elevator, I replaced it with by a wooden one with metallic connectors, Isolted the conector with thernal shrink, I also isloated the internal section of the receiver antenna exposed in the fuse with silicon tubing, and also made sure that there's nothing metallic touching or rubbing receiver antenna. I also changed the antenna location, it goes through the fuse by the posite side of the switch.
After doing all that I noticed I still had elevator signal glitches, I can not think of anything else, the only things that have remained untouched between the two planes are the other servos:rudder (digital JR), Throttle (futaba S3003) and ailerons (channels 1 and 7-Futaba digital S3151), the rudder (digital servo) and throttle are kind of old.
Furthermore The ailerons servo are plugged into the receiver only by 6"extension (Golden terminal), the additional length for the servos is put in place by soldering additional servo cable.
I am wondering whether the elevator channel glitch could be generated by a faulty servo (rudder or throttle, aileron). Is it possible?, If so which channel could be interfering with elevator?
I am really going crazy with this issue I have nothing else to do or change (besides the servos) I have never had this sort of unknown glitches, I running a 10CAP system.

Thanks in advance for the attention paid.

With several servos, all of different makers and long control leads, it's not really possible to determine the difficulty. If you remove the receiver from the airplane, plug in all Futaba servos and perform range checks, you should be able to determine if the receiver is at fault. A non-Futaba servo may cause some kind of feedback that is showing up as an elevator glitch. Long control leads can act as antennas and cause glitches to get into the system, and show up, in your case, on the elevator channel. Solder joints can cause problems if they're not good, dirty connectors, and of course bad equipment. You may have a bad servo or receiver. All need to be carefully checked.
