Over the years I have heard conflicting views whether intake ducting is important or not , I am interested in people's views and experiences on this .

From a performance point of view I don't think it makes a huge difference, the
engine will suck air around all sorts of obstructions.

I'm not a big user of ARF jets but from viewing friend's models with glass fuselages
there seems to be a structural weak point where the big intake holes are made in the
mouldings. I think ducting properly bonded into the fuselage would stiffen up things
in that area greatly.

Cosmetically, ducting looks heaps better than looking at all the gubbins of a turbine
model through gaping intakes!

In my experience intake ducts can make a big difference to a jets top speed, but this probably depends on the jet, also bypasses make even more difference than an intake duct but these can have the opposite effect if they are not set up correctly

Full duct gives you less dirt in the turbine and less noise

What power unit. ?? A must for fans.. Turbines, not so much , if at all. helps dirt and cooling and internal drag

Depends on the airframe! But there can be a lot less drag with correct inlet design. The CARF Hawk we went without as the inlets are small and volume they feed huge, same on the Tutor. Many models have larger than needed inlets, some are very noisy as a result.
