The Rotax 916 will help sell a lot of new aircraft of all types.

[facthunter]

What is the Current Price of that engine? Nev

Price $49,999  USD

May be.

 

Strikes me that the Rotax 916 is most likly going to power very much more expensive aircraft than say the 912ULS.

 

The Jab engine (with/without Jab aircraft) have allowed many to enter/own a rugged low purchase/operating cost aircraft.

 

The Rotax 2/ range followed by the 4/range has delivered in a similar (slightly more expensive) way.

 

The  relativly expensive & complex Rotax 914 (turbo) is poplar in the USA and Europe where high mountain ranges may be crossed - not so much in Australia where most Rotax operate below 10,000 ft

 

I think the 915 & 916 will compete with the 150 - 200 hp LyCons  and will therefore have little impact on the lower end of the recreational aircraft market.😈

[facthunter]

A lot of money.  Nev

[facthunter]

 IF you want to go over big Hills you do need a boosted engine..   Nev

[skippydiesel]

"453 kmh =  244 knots all from an RAA registerable aircraft"

 

True! Now that RAA has ventured into aircraft with a TO weight above 600 kg.

 

This move puts RAA in competition with GA  - I doubt it will be very attractive, as maintenance etc is as for GA ie for many owners, the low cost of maintain their RAA aircraft, was one of its biggest draw cards.

 

The idea that the Risen can be classified as a "Microlight" is patently ridiculous😈

Seems the way of the world, looking at close to 100k for overhaul of most 6 cyl aircraft engines now.

Our money doesn't buy what it used to, it's that simple. Try comparing eating out and land prices, they've gone up enormously, since the start of COVID. Repairers and tradies charge around 50% more than what they used to, 5 years ago.

You can still get a very nice preloved Jab aircraft for under $50K, Rotax 912 ULS power aircraft under $100K. Build a new composite kit for around $160k - Factory $200k.

 

Naturally you can do even better or worse, depending on how urgent, picky, loaded you are😈

[BurnieM]

Bristell are already using Rotax 915 and 916 in one of their 2 seaters.

And people are buying them.

Your point?😈

[red750]

Interresting that Vne is listed as 420 kph.

 

Can LSA's have retractable undercarriage? The profile, copied from Wikipedia, lists a retractable and a fixed gear model, but all photos show the retractable variant. Illustrations of the fixed gear variant are CGI.

Ah! Could it be you are suggestion that a Bristell, with Rotax  915or 916, is competing in the sub 600kg TO environment?😈

[BrendAn]

244 knts seems way too fast for a lightweight aircraft.

Imagine what rough air would be like.

That's why I never take the xair over 200 knts.

[RFguy]

916 turbo Risen :

Vs0 stall speed 43 kn. 

Now, Vs1 (flying config stall speed) for the 916 beast is 55 kts. 

 

I wonder what the load factor rating is (IE Normal or Aerobatic)

https://www.flyrisen.com/risen-SV916

https://www.flyrisen.com/media/downloads/Risen_912-915_Data-Sheet-Risen_metrics_US.pdf

 

OK : load factor is  +5.0/-3.0   which is not bad I guess.

 

 

43 kts x sqrt(5) Va =  123kts.... respectable if it flys at say 140 kts.... 

 

75%  (916 turbo)    is 180 kts  (sea level) 

 

so you are flying along at 180 kts   and you hit some rough air or CAT, hit a big bump.

and the wings instantly separate from the fuselage... nice.

 

 

I dunno.....  I would be nervous goign fast .

https://www.kitplanes.com/risen-the-master-of-efficiency/

 

The 912 powered Risen seems a much more SENSIBLE combination to me. 

 

Va compared to a Lanceair 360. Lanceairs have high wing loading and not terribly light.

Vs1 for a Lancair 360  in one reference i looked at is 74 kts, and the load factor is 9G . yes 9 LOL.

so Va is 222 kts .... it ain't gonna break easily. (cruise is 203 kts) 

I think I'd have a Lancair.

Or a Comanche

Anything with 915, 916 and injected 912is need extra maintenance and present additional trouble shooting skills when codes present.  Need available the reader as well.  Plenty of fuel pressure pump matters and turbo (eg waste gate needs) that will not be good for the do as little as possible maintenance / service tribe members.  A mate up here purchased the reader as he had a fault code to attend to, he said happy to loan to me however I only want to work on carb and non turbo.  Working marine life exhausted me about turbos; give me NA any day for reliable performance.  Just my opinion.

[onetrack]

Simple turbos alone, are good. Turbos + lots of electronics attached to them, is bad. The Europeans are masters at making things too complicated, and then also charging much more than anyone else, to supply parts for their products.

Yeah but then you have to fly a Jab.....

[RFguy]

It's an attractive powerplant. But its not without it's misbehaviours  as BlueAdventures commented.

I have seen plenty of fodder to suggest that it's still an enthusiast's engine, not mainstream.

I certainly would love to have one, I'm a enthusiast.

 

but those messages - 'random' - but they're not ---  alarms and messages.  and what i think is almost dangerous behaviour by the ECU in case of a sensor failure.

example - engine on climbout at 500' loses a non critical sensor, and spends several seconds at idle/ shutdown decides what its going to do... scaring the fu3k of the pilot.

when it should just keep on trucking because it knows the engine curves, required fuel injector timing etc for some RPM. WTF? 
I talked ot Rotax abotu this behaviour and they said a pilot should never be flying over what they cant immediately land on. Sure thing.

also Watch out for the, what I beleive is inadaquate  choice of connectors for the power/alternators for the 915.

I could go on.....

 

Having said that, yes, everyone's a critic, and it is I think the very best powerplant out there aside from Lycoming.

The Jabiru isnt bad.  Years of what I beleive of poor decision making at the top of the company have severely damaged its reputation.

That has changed now and the voluntary recall of all those 3300 crankshafts at their costs proves the point that the organisation has turned a corner under new ownership.
 

Many european manufacturers think regulation knows best. Fortunately, finally some of Europe is figuring out they cant compete with anyone  with their regulation and approach. 

The China EV competition experience has perhaps changes some of the minds in Germany.

Injected engines are not new.

Turbo charged engines are not new.

 

I cannot recall any motorcycle you could buy in the last 30 years without injection and no car in the last 40 years.

Yes there are more moving parts but most kinks were worked out years ago.

Injection is a very good solution to the mixture problem.

Engines should give better economy, better power and last longer with injection.

 

912is are a very nice engine with similar performance to a ULS but better cruise economy.

 

Yes these engines have diferrent failure risks but I wonder when I hear 'carbs are reliable' whether both engines are being intelligently assessed.

 

Turbo chargers carry their own potential issues which is probably why these engines come with many performance and warning sensors. 

Modern efiss like the Garmin G3X Touch give useful messages to hopefully prempt any issues.

But how else do you get a decent performance package in a light weight engine ?

 

Sorry Jabiru dont do it for me, at any cost.

?  So who are the new owners ?

[GolfWhiskeyHotel]

Looking for Jabiru engine prices. Could only find in the US.  4 cylinder  $22,000 ( $43,000 AUD?)    and for the 6?  got to be around $56,000   AUD  That's not peanuts!  But, saying that, I got charged $163 dollars per hour 

at a franchised repair shop for fitting rear rotors on a car.  $163 per hour!  ridiculous price.  When I started work I got $3 per week for 44 hours. The world has gone mad.
