Hi Gaz
Thanks for the tip.
I hadn't noticed that yet as I've been rather busy lately
what with fixing kev's PC9 and Temora.
Yea Darren had a look at the turbine installation and we worked it out.
Rather I should say he worked it out for me.
You will notice in your L39 that the 2 wooden formers nearest the turbine location are notched.
What we did is glue in there 2 basswood railsthat extend towards the forward end of the plane.
we used 5mm Basswood but we also had to pack a piece of timber on the inside of the notches
to get the rails to sit exactly the correct distance apart for the Stumax.
We found that a popsicle stick is just the right thickness.
When you install the Stu you will then see that it is not directly in line with the inlet tube.
What you have to do there is cut the included inlet adapter at an angle that corresponds with the amount of offset. Suggest you get a piece of cardboard and make a dummy adapter so that you can practice cutting the angle. (It's a bit of trial and error). Once you are happy with the angle cut your adapter the same.
What you will end up doing is slipping on the adapter upside down and loosely mount your Stu to the rails then turn the adapter to the correct angle and you should be able to slid your Stumax forward and tighten. This should then allow you to mate both ends up to the Stu and Inlet Pipe for a flush tight fit.
Then seal with something like fibre tape etc.

Probably easier to show than to describe. I'll bring fuselage along on the weekend and show you what I'm talking about.
