after posting i went and checked the plug cap. it wasnt on fully and i had a lot of trouble getting it on , i had to slide back the round clip on the plug cap and then when fully pushed on i slid it back down toawards the plug and voila it works better with a lot less glitching, the tail rotor servo is stil doing its own thing a bit but its a lot better,so thanks for your reply you were on the right path.

So, your heli has a CDI with its own battery.

Your receiver also has a battery.

Try to run both systems independent as posible.

Check all cables on your helicopter, need to be as straight as possible, avoiding "pigtail".

Isolate the servo which have the interference. Install a ferrite ring in the servo's cable.

If your are using bec's, install ferrite ring to cable output to receiver or CDI.

Do always a range check prior to fly your gadget.

Frecuency?...

I do the job by trial and error.
If There are some basic math, I would like to know.

Depending upon ring diameter, I usually do three turns with the servo cable. It is necessary to remove the plastic connector and then reinstall.
