Hi Gaz
Here is some photos of my installation.
First off we epoxied in 10 x 5mm Basswood Rails.
In order to get a nice snug fit around the Stumax housing we found
that it was necessary to add an extra piece of timber into each rail cutout
first. We found that a paddlepop stick was just the correct thickness
for this.

   

Next we inserted the Stumax and pushed it as far towards the back
as we could to facilitate the installation of the Inlet adapter.

   

Now you will see that the Stumax and the Fibreglass Inlet ducts are
not quite in line and require you to modify the supplied Inlet Adapter.
Before you stat cutting this adapter I suggest you make up a cardboard
adapter and practice on this getting your angles worked out etc.
This next photo shows my finished adapter. Note how we had to shorten the adapter first then cut an angle on the short piece and bond it to the straight piece.

   

Note that I have also applied some tape(one sided) to the front edge
of the Stumax. This is to provide a seal around the join of the adapter and edf.
The adapter gets inserted upside down into the fuselage with the EDF
pushed far back. Once inserted turn adapter correct way up and ensure
that the adapter snugly fits around the Inlet Ducts.
When happy with fit push Stumax forward into the adapter and screw down onto the mounting rails. This should stop any chance of the adapter moving in flight. You can now seal the adapter/EDF union with
some tape.(not shown)

   

Some things to consider before doing above.
If you are going to install an exhaust tube you had better do that first and attach to the Stumax as it will be impossible to seal it after edf is mounted.
By only sealing the adapter/edf join with tape it will be easier to remove
the edf and adapter if you ever have the need.
Hope these photos help you. I'm looking forward to seeing you maiden her.
