Ouch!
I think we need more info to help, please list your equipment and installation location of the equipment. It is critical for some setups to install the esc, rx and gyro in specific locations to minimize the glitches. So, more info given the more info you get!

I'd make sure the rx antenna is rearward then slip the wire thru the antenna tube forward pull snug fold back along tube and put a fuel line keeper on front and back ends. Zip tie the esc on right side of frame to maximize the distance from the antenna tube. Gyro on rear under the boom block, batt on the angle plate. Check the gear lash and belt tention. If you are using the futaba 146pcm this should minimize any glitching. A ferrite ring on the esc to rx lead won't hurt. When you zip tie the esc to the side frame put a tie over the heat fin block to keep from loosing it. That my friend is all I have for now!

Hi!

I was having the same problem. Changed the ESC to the side, as far as possible from the antenna, which isn't touching any carbon or metal. Gyro on the back, over the receiver. I am using the Align 25A esc and 420LF motor (not really good I know, planning to change it for a JGF 450F and a jazz). Receiver is a 6 channel GWS
It is a little better now, except at this "Bermuda triangle" on our field, where I still get glitching. Argh!

Getting a ferrite ring and a a glitch reducer. PCM receiver... later if nothing works. Then, I don't know, a rabbit paw perhaps?

I will try some/all of these things, and keep you updated.

Make sure that you are not flying the Plastic fiber blade, one that weights 60g. When I fly with this blade, I get big time glitches all the time. After, I chage to a wood blade 40g, the t-rex fly with no problems.

If your machine glitches more with heavier blades, the glitching is coming from your mast bearings. Replace the mast bearings with higher quality beatrings, and this problem will vanish

I'm going on a limb here. I noticed that your using hitec 65mg servos.
Have you ever tried non metal gear servos on cyclic, to rule out the high frequency effect they might have? Or if anybody here is Currently using mg servos with sucess to tell me I'm way off!
and one more thing "DON'T BE AFRAID!"

If you open the case and apply some bearing grease to the gears, the interference possibities dissapear. I am currently using JR 241 Metal geared servos on my Trex with absolutely NO glitching on aFM receiver!
