I have quite a lot of experience trying to remove interference using 35MHz from the Dragonus and I would say that you have to ground absolutely everything, including motor casing, boom, tail gearbox - the lot - all strapped directly to the earth of the battery.
I tried lots of things including ferrite rings, opto-isolator, base loaded aerial, different receivers including separate one for the throttle, changing ESCs (some are definetely better than others) Even removing the boom and belt didn't get rid of the interference !!
The only thing that cured it was to GND everything, so get a multimeter and make sure it measure zero impedance (resistance) between all parts. Remember the anodising doesn't conduct very well, so needs scraping away in key locations (and where you measure to), as does the coating from the carbon boom.
Or go 2.4GHz
Also check for wearing balls, as they are aluminium and can wear very quickly leading to links popping off.... flies surprisingly well with no flybar control
Maybe there are some stainless steel balls that will fit ?
Well worth the effort though, as it flies superbly.
