Thanks, guys.
It is most certainly the SAPHIR unit that is sat on the bench. Starter unit is still on there plus theducting on the other end. No controllers with it but there is a spare hot section.
Question is....what to do with it. Might be a shame to cut open a useable unit. Anyone have something appropriate to trade it in for? We only got it so that we could see the working parts of an engine.
I'm bringing a Briggs & Stratton mower engine in so that we can open it up, put it back together and then run it. Much more fun than looking at books!
I brought my aeroplne over a few weeks ago and we ran the engine up for a few minutes. My prop-swinging arm is still a bit sore. Stale fuel!
