DooMaw - building a STOL
rgmwa replied to Head in the clouds's topic in Aircraft Building and Design Discussion
QwikEFIS might be worth considering. http://members.iinet.net.au/~ninelima/efis/index.html I have no connection with the author and don't use it personally, but it looks like good piece of software for Android devices. -
Is there a link to John Brandon's tutorials?
-
The current system seems fine to me.

... and the Thruster! -
Protruding rivet heads may make it difficult to get the wrap to stick around them. Any voids under the vinyl might become a corrosion trap?
-
I don't think so, Ian. I have a PPL, my plane is GA and I'm not in RAAus, but recreational flying is what I do, so the name works for me. There are also professional pilots on here who fly for fun in their spare time.

Is there an option to turn off the timeline bar on the left side of the screen?

I agree. The iS package from Vans is $5,000US more than the ULS. I don't know what Bert Flood charges for the iS but I'm sure it will be a lot more than the ULS. It's also difficult enough to find trained Rotax mechanics locally, and those with iS experience will be even more scarce. It may be different in Europe, but I think that for us in Australia the ULS still makes a lot of sense. However, the iS is certainly a nice engine with impressive performance and if I was building again I could be tempted to try to find the extra cash. Fortunately, I'm not building.
-
Just for interest, Vans publish these performance figures for the 912iS and 912ULS respectively in the RV-12, based on their testing: Range (7500’ @ 5500 rpm) 630 miles 433 miles Range (7500’ @ 5000 rpm) 605 miles 435 miles Tank capacity is 20 US gal, all useable. Miles are statute miles. These show that the iS is significantly more fuel efficient than the ULS.

I flight plan at 19. I did a long trip recently (over 4,000nm). Tacho time was 45.0 hrs and I used 773 litres giving 17.2 lph average. Time spent warming up, taxying, descending/climbing etc all affect the average fuel consumption so 19 lph is about as near as I can determine for steady cruise. I have a fuel flow meter, but it's only as good as its calibration, and in any case only measures fuel going to the engine, not fuel going back to the tank via the return line. Even in steady flight it can fluctuate between 16 and 20 lph for no apparent reason so I don't rely on it.

I wasn't telling you to spend $50k on a plane. I was giving you an example of how you might estimate the fixed cost of owning it if you paid cash for it. All the running costs and other ownership costs are obviously on top of that as per the video. I suggest you contact a flying club and find out what it costs to hire a Cessna 152. That will give you a rough but useful idea of what it will cost you to own a plane like the one in the video yourself, You may do it more cheaply, but if you don't fly much it may work out more expensive. The video is not very relevant to Australia except as an example of the kinds of things you may want to include in your own cost estimate.
-
Buy it for $50k, keep it ten years, sell it for $30k, fly an average 30 hrs per year and your cost to own it is about $67/hr. Change the numbers and assumptions to suit your situation.
-
Hard to answer because there are a lot of variables starting with the type of plane you have (size, age, buy or build, VH or RAAus), who maintains it (you, LAME), cost of spare parts, cost of hangar or wherever you keep it, insurance, rego (more applicable to RAAus), fuel costs (avgas or mogas), how much you fly, etc. My plane is paid for and probably costs me roughly $100/hr to run in round figures although I've never really worked it out and it will vary markedly depending on hours flown. That's cheap in aircraft terms.

Whichever style works best for the site is fine by me.

Serpentine's annual fly-in is on next Sunday 14th Oct if anyone wants to come down. Apart from the aircraft, various car and motorcycle clubs, miniature steam engines and other exhibits usually turn up and it makes for a good day out.

Yes, he went into the scrub bordering the field. I believe he was knocked around a bit but recovered. Didn't know him personally and have no idea where he is now.
-
Correct. The jet powered Cri Cri is based at Serpentine. There are around 130 aircraft on the field - from memory around 80 experimentals, 20 or so vintage/warbirds and the rest are commercially built. Interesting aircraft include several Tiger Moths and Austers, a Fox Moth, Sopwith Pup, Bucker Jungman, Stearman, Pitts S12, a couple of Tailwinds, Yaks, Culp Special, Stinson, Spitfire replicas, the Silver Centenary, Pietenpol, plus plenty of Jabirus, Zeniths, about 23 RV's of various types and well as Cessnas, Pipers etc.

I'm VH experimental so not in RAAus.
-
Just paid $2100 for $80K (should be more) hull cover and $2m public liability with $1,000 excess. Next time I'll look at increasing both excess and hull cover.and see how that affects the premium.
-
My mistake. Looked at the wrong picture.

With or without you in it?
-
Did you spill any drops of mogas on it? That will cause almost instant cracking. I'm about to replace my rear window for the second time for that reason. I wouldn't be too concerned about your window failing in flight.
