I recently reconfigured my Shogun to fit a longer battery--the main change in I moved the receiver out from inside the frame (where it was cushioned with foam) to the standard spot up top. Before the move it flew great, no glitches. Now, it has glitches "of unknown origin."

The strangest case is shown in the photos below. With power on, but the ESC NOT armed, the glitching starts when I simply touch the heli, most anywhere, but especially if I touch the wires (as shown). All servos "twitch" and jitter simultaneously. I don't dare arm the ESC, or try to fly it.

Anyone have any clues about where this glitching is coming from?

Static from the floor mat?

Is that the same antena you were using before, I tried one of those on my Hornet 2 and could not get more than 10ft away on a range check before everything went wild. Glitches can be such a bear to work out, look for any wires that are crossing that wern't before. I put a standard stiff antena tube on mine between the landing gear and my glitches are finally gone.

I would say that your antenna wire strapped to your battery is the problem you do not want the antenna wire touching anything electrical because the emf produced by the battery can cause the glitching and so I would say move that clear of the battery and you would clear up the problem.Also I see you have a Hitec RX those are not the best when it comes to trouble free I used one of those on my Heli's and had some problems with glitching so I dump them and went to a Berg RX and have been trouble free ever since,but the wire on the battery is a problem also.Also Deans antennas are the best if you have done a good job soldering the connection on the plugs and not cut the wire to short. Also I don't think you will get static from rubber mats since rubber is not a conductor that is why I stand on them when working on large electrical panels at work so I won't be grounded.

Thanks for the responses, guys.

I thought about static, but it happens on my workbench, too. And, yes, it's the same antenna as before--good solid solder joint, and pretty good range check (only slightly less than before I cut the stock antenna and mounted the Deans). I know I don't have a signal problem from the transmitter 'cause the servos respond normally to control inputs, even when it's doing the glitch-dance.

I've got lots of wires crossing (not the antenna) among the servo and ESC leads--I didn't think twirling them any which way would matter...maybe it does.

I'll also try rerouting the antenna, but the odd thing is I had it next to my older batteries (insulated with velcro and foam) with no glitching problem. The yellow-wrap in the photo is medical wrap like you get to cover the site when you get blood--holds tight, and seems to insulate. Maybe it ain't doing so good!

Again, thanks for the ideas...
