Not often, but i now need a coffee break. This question has been asked about 20 times, and also has been duefully covered.
A bagle to go with the coffee would be nice!
FWIW,
separate the two as far as you can manage, do not rely on modern devellopments, test your stuff on low transmitter power with ample distance and engine running.
Do not believe those who say they never had a problem. They lie!
I am sorry for the sarcasm. I did however offer good advise.
If only your throttle servo acts up there may be reason for that.
Use a new servo, and check disturbance again. If so, check out why. Do you have a
metal (or conductive ) pushrod or pull wire? Is your ignition some way sending out HF signals by loose wires, insufficient shielding etc?
Such disturbances, if only affecting the (hopefully healthy) throttle servo indicate strong fluctuating electric fields that influence the servo's electronics and make it act up. The other parts are probably too far away. A conductive steel or carbon rod, wire or anything else that can lead the HF signal from the ignition to your servo vicinity must be avoided.
