I'm just intrigued as to how they handled the logistics there. Did someone hiding in the rear seat actually remove that wheel mid-flight in order for the stunt to happen?

Ah yes but your Hurricane is the plain sister compared to the supermodel that is the Spitfire. Capable, yes, did the heavy lifting, yes, but beautiful?

I agree - to me PSI and BHP make more sense than KPa and Kw. But metric in everything else (and I get picky - metres and millimetres exist, centimetres don't...)

You wouldn't be Robinson Crusoe there, OME.

Thanks Jerry! Downloaded and reading.

I believe the bloke who's building a 1:1 scale Spitfire here in Hobart is planning on using a Chev V8. Can't remember his name now - I have met him at the Sandfly strip, there was an article on his build in the ABC a year or two back.

10 years actually - I bought one for the house a couple of weeks ago.

Skippy, I'd be very interested to hear what they advise too.

Yep... 'cos there'll be such a market for more new 737's in the next 5 years...

Yeah but with other cars you don't need to order parts every month...

So try #2... got the jig made up today and strapped the muffler to it. (Upside down, obviously, in the photo below). Screwed the outlet stubs to their equivalent positions. Also made up a protractor to help with cutting the angles in the donuts.

That's it Mark, I'm waiting for your product! You could blow some aerodynamic covers and voila, a wig-wag/landing light kit. The other alternative of course is to mount in the leading edge. I'm seriously considering that as it'd only have to be a thin bit of polycarb riveted in and your curve is automatic. Plus you get the lights further apart out in the tip. In fact if you had a second LED set on the actual tip attached to the same controller, you've got visibility from the side as well. (I may be going overboard here).

It's a very neat looking installation Bob - you should be proud. One day when this is all over I'd love to come to NZ and see your pride & joy!

By that reasoning, ultralights should be really bright.

All the A380's off to the boneyard I hear, spending the next year or 3 sitting in a desert with shrink wrapped engines. Would have thought we could build one of those somewhere in the outback, haven't we got any low-humidity deserts here?

I've been there, unfortunately wasn't one of the lucky ones who got chosen for the whiskey tastings. Our German friend was though, and she was quite funny after "tasting" 4 or 5 of them.

Hi Mark, I think it's the same as yours - number stamped on the end is the same anyway, 973 674. I took a photo down the end as best I could, from this end you can't see the trumpet flange, it's at the other end by the looks of your pics. This is a new muffler kit thrown in when I bought the engine, when the bloke put in his new Rotax he kept the same muffler setup in the plane so he had no use for the new muffler.

Yes I have to actually take the filter off to see how much room it requires. Strangely, when you look at the pictures of commercially available systems, the front left pipe seems to be angled in the same as the other (example below from CPS Parts). Mark, it's very similar to the one below with the outlet at the bottom of one end, it's reasonably weighty so I reckon it has a baffle. It came with a stainless steel exhaust pipe that has an elbow like the one shown. Still a bit confused as to whether it should be welded straight down. Any advice?

One of those days. I'd drawn up the jig for the exhaust runs, bought some framing pine from Bunnings, looking forward to a day in the shed building it. ...Then I decide to double-check the distances from one cylinder's outlet to the other, and how far the starboard cylinders are ahead of the port ones, and realised I'd got the measurements wrong by 14 mm. So instead of a nice satisfying shed day, it was spent on Sketchup redoing the whole thing. I also redesigned the back pipes which I think gives them a smoother run and looks more like the exhausts you buy for this particular muffler.

Most controllers seem to come with 3 options, I'll put in a 3-way switch for "just in case". (eg just in case I'm landing at dusk, you can choose the "both on" option as landing lights. I know you guys in QLD don't really get a twilight, more like a light being switched off, but in lower latitudes it can be quite long.)

I've been told that the aerosol moves it around enough after you spray it in that it coats pretty much everything. I'm doing mine once a month - was using RP7 but picked up the Inox today.

Still nothing Gareth.

CrazedPilot are possibly a bad example OK - I had a look at their reviews on Ebay and they were pretty bad. I'll spend a bit more time (and money), your Sparxfly unit looks good.

At the strip I hope to fly at, I've seen one on approach at dusk, in fact I would have thought it was a bit too dark for safety but it was still technically daytime. How'd I see it? Because it had landing lights on. We can argue about the benefits until the cows come home but the main points are: 1. The guy who inspects my aircraft knows the local strip very well and advised me that it'd be a good idea to have some kind of lights for added visibility. 2. An entire wig-wag system (using the CrazedPilot one as an example) weighs less than 200g total and costs around AUD$115 delivered from the states. So to me, it's worth it. To others it may not be.

Sounds like it'd make a good BBQ! (After contents safely disposed of and volatile compounds gone, of course)
