Test fitting the turbine it became apparent that it's sitting too high so I've bolted the mount onto the bottom of the ply rails lowering it just enough so it sits in the middle of the inlet and pipe. I never like bolting down onto ply as it bites down a long way into the wood and because of the way Ive mounted the bracket when the model is pulling G there will be loads of stress on these four small areas so I made some glass board plates to bolt down onto. For turbine brackets I always use aeronuts these are a bit like nylocks but don't contain any plastic so ideal for high temperature applications such as this. I wanted the turbine as far forward as possible so I trimmed the inlet ducting back to the former and found a position I was happy with allowing a suitable gap between the pipe and turbine. This also means that the pipe doesn't stick out the back end of the Jet. The two fuel lines will go though the ducting and out of two holes as the bend to get round the inlet is a bit tight. I fixed the pipe with it's two steel extensions. I used 2 socket head screws a side which proved to be ample as it's rock solid.
