I agree with this in principle, this is one of the things we had considered doing.
I think you have hit the nail on the head with regard to turbine models. if you consider what you actually have, it is more like an electric model!
ECU (spead controller but more complex) pump (motor) high power nicads, valves, heavy cables etc.. all add up to a lot more electrical noise. More care must be taken on the instalation to isolate these items, keep power cables and data cables apart.
The other thing i have just recently had experience with is carbon fiber causing problems.
My L39 had many uneventfull flights under its belt, but after a fuel spilage the foam in the composite on the bottom of the fuselage nose became soft and week. I removed it and replaced it with carbom fibre strands running front to back on the base of the fuselage.

Flew the model and had 2 'holds' lasting about half a second or so, not long enough to engage failsafe.
Landed and range checked, my range was reduced considerably. Fully checked model, changed receiver, xtal, checked tx with another plane.
All seemed well but still had bad range. All i had done was put carbon strips in.
I ripped the strips out and replaced them with balsa section and thin glass cloth.
All of my range returned! Have flown uneventfully ever since.

The carbon i had put in laid under the output of the rx and ran forward about 1 inch away from and parallel to the ariel.
I beleive it was picking up output from the rx and acting as a tx ariel, feeding it back into the rx ariel.
I have repeated the condition by layng strands in the same place, and guese what? no range.
I believe that most turbine crashes that are atributed to lock out are as a result of instalation problems.
So it is a good use of a PPM rx to check out your instalation before you fit your PCM to fly.

Also we have much more carbon in models these days, from my recent experience i would warn against carbon being anywhere near power cables or data cables where there is a clear electrical path back to the ariel.
