To the OP.
A lot of folks here trying to help you but you don't seem to be answering many questions.posed to you.
I'm not as anal as some folks with their installations but looking at your pics you really need to clean up the install. Get the wires separated power and servos and bundled together and secured. Ignition battery mounted close to the ignition, no metal to metal control rods,etc...etc...
As far as the servo being too close, I have an ultrastick with a chicom 40cc engine and ignition. Ignition is on the firewall and the standard size case servo is about 4" away and wires are run on opposite sides of the fuse. I have no servo problems.
