Interesting. Is your 0-200 a Continental? Did you do any modifications to it to run it on 91 Unleaded?. I would have assumed it would risk detonation otherwise. So from what I'm reading here (Conts and Lycom) are considered low compression engines. Yet many still run on Avgas rather than Mogas. Is that a manufacturers requirement. Why? Are modifications required to run these engines on Mogas. If so, anyone know what mods are required?. Cheers

Yes I have read a bit about the Viking. I liked the look of that, and the Suzuki. Haven't heard much more about them. How many are being sold and installed in aircraft nowadays. Perhaps not hearing much about them is good. Are they being used and we are not hearing much about them because they are reliable?. Bex. Yes, I didn't know car engines were high compression and have been for so long. I guess I just assumed if they were as high compression as the old Cont and Lycos, they would require higher octane fuel than the 91 most car engines can run on now. Depending on parts pricing though, this new engine sounds brilliant, as it takes us back to the 2700 rpm engine many of us are used to from GA, with no gearbox required. I certainly like that. Cheers

Yes, realise it's not a 0-200, but they did say it was a 200 Cu/Inch engine based on the 0-200 I didn't know modern car engines are equally high compression as the old Continentals or Lycos. Big question is going to be price. Are they stating it will likely be half the price of a O-200 ($12500), just to spark everyone's interest, then when its finally released, the price escalates. Realistically, If they want to get a huge footing into the market, they need to keep the price down, otherwise people generally stick with the known, trusted brands IMHO.

I just thought if it was a O-200, to get 126HP at 2700RPM / 4 CYL, it would be high compression requiring Avgas. Even better if you could run it on Mogas 95 or 98, or Avgas.

Certainly hope they are successful. If their cost estimate is correct and the engine is reliable, They will likely become the No1 engine choice for Light aircraft. I noticed they cut the high power video short. Not sure why. More development required. I didn't see the fuel type mentioned in the article. Mogas (98?) or Avgas. I would guess Avgas. Good luck to them. I will be following their progress with keen interest.

What trashy sensationalist reporting. The so called reporter stated 'The engine stalled'. No one else mentioned anything about an engine failure. Another reporter to avoid.

Yes, strangely the $22500 engine does not include many items. Radiators - oil and water, exhaust, engine mount, tanks, tubes, air box, filters. Not sure how you get on with warranty if you don't use those extras, making your own for example. Those extras are $6500. Then strangely, after asking for prices in Australia, GST is NOT included in the prices. Maybe I don't have to pay it for some reason. Quick tally = $31975. Maybe other parts needed, freight. Installation cost on top of that. Then if you require new cowls etc. Maybe looking at $35,000+ to re engine an aircraft.? Maybe someone on here has done it. Id like to know your final cost.

Yes, I've been keeping an eye on those engines too. He made the Subaru aero engines before his company went bankrupt in the big depression (2008-2009). Then started Viking. One thing I did like about the D-Motor was higher capacity engine, working less,.... and direct drive. Closer the Lycomings I like.

I am / was considering buying a used aircraft and replacing the engine with a 912ULS, but at $31,000 or ($33,000), plus any extras (eg: $1500 for engine mount, etc), I don't think I can justify it. You would never get your money back later, when time to sell, and it would cost more than many other used LSA out there. If it was $11,000, I would have done it already. Hence the interest in D-Motors, or even the new design Jabiru engines. But we will have to wait a lot longer to see how they both pan out. Certainly if a reliable $11,000 alternative was to become available, perhaps then, Rotax's only customer would be the US Military. You can buy a pretty decent new car with a damn good reliable 180hp (ish) engine for $33,000. It just doesn't really add up. (Yes, I know, car engine vs aircraft engine).

Thanks. No duty, that's good. Funny how opening that link takes you to Nuclear Reactors 5% duty at the top of the page. Id rather a Rotax 912 anyway.

So that would be around $25,000 for the 92HP D-Motor. I recently priced a Rotax 912ULS. It was around $31,000AUD (without knowing exactly what of the listed options I would require). Difference of $6000 here in Aus.

OK, thanks. So about $1500 now including gst. Maybe a bit less if your $1250 included gst. Was that for a D-Motor or Rotax from Europe?

Funny you should mention that. I had written that in my last post, but then deleted before posting. The 92HP LF26 is listed as $20,700 delivered on the Aus website. However I've just found them advertised in the back of the Sport Pilot magazine for 12,600 Euros + shipping + GST. Not sure, don't you pay GST on shipping. How much would shipping be? Would there be an import duty on top of the shipping and GST? I would expect it to come out higher than $20,700 AUD delivered. Good price for a LF26? I hope they succeed, but I would prefer many more examples clocking up hours. The Rotax is very over price IMHO, but there are not a lot of alternatives. I've just searched the Tecnam P2002 reviews. I was very surprised to see the number of accidents world wide, that seem to note (engine problems) for the accident. They have the certified Rotax 912. I don't know much about the aircraft, hence researching, but are there that many forced landings with Rotax 912 engines happening? That's all I'm flying behind at the moment.

Thanks xair. I'm glad the D-Motor is working well for you. I really thought after 5 years (since this thread started), there would be more of them flying. Hopefully as more engines clock up a few hours (reliably we hope), they will become more popular. Cheers.

Yes, the oil leaking past a bearing explains the oil in one of the cylinders. No explanation yet (that I can see), as to what caused the crack in one of the cylinders.

Thanks xair. That's good to hear a positive report. Are there many other D-Motors operating near you? Looks like the 'cold water cracking heads' was false. He said it was oil leaking past a rod. Check Kyles Savannah link a few posts back. Cheers.

The Foxbat has a bar across the top of the cabin. I was concerned in a sudden stop, I would hit my head on it. If you are long in the Torso, it may be an issue. Normal flying it wasn't an issue. Only way to know is have a sit in one yourself. Tall pilots sit further back, with their head high in the cabin. So your eye level is only just under the wing. I find this restricts your view, and with the belts snug, you cannot lean forward to get a better view sideways. (as I used too in Cessna high wings). The low wing are always at the higher end on the 'hourly rate' scale it seems, possibly as they are more expensive to buy. I prefer low wing aircraft, but strangely, I've only flown high wing LSA lately.

Thanks Kyle. ----------------------------------- That's the only recent Info I can find on this engine. That's a bit strange considering back in 2012 there was a bit of talk on the LF26 and the nearly released LF39. Internet searches on reviews or reliability draw a blank. Wonder what has happened. I was hoping there would be quite a few 4 & 6 cylinder models clocking up some hours so we could get an idea on reliability & cost of operating. If cold water is cracking heads in Sweden in Summer, I wouldn't want that engine in a Swedish Autumn or Winter. Very strange explanation of that engines issues. There must be plenty more of these engines out in aircraft now (5 years later). If anyone finds anything, please post here. Thanks.

Thread revival. I like the look of this engine. What's the latest on it. The last post was over 18 months ago. Reliability Number operating worldwide / and in Aus. Any issues 6 cyl version Actual fuel flow figures 4cyl / 6cyl Cost of operating compared to Rotax 912 I read a few pages back, someone ordered one in Aus a while back, then cancelled the order. Some issue in Aus? Thanks.

I'm glad I learnt to fly in the days where no one would consider charging for briefings.

Never operated one in that lower Ground temp. But good to know. Noted Thanks

No, That's 'Immediate Landing', Uncontrollable fire, Smoke etc.

Depends on what your airline considers Suitable. RWY Length / Width PCN Rwys / Twys / Parking RF Maintenance Ground Agents Suitable Airbridge / Airstairs Accommodation / Transport for PAX Tug / Towbar Rwy Lighting Nav Approaches available Weather Doesn't tick many boxes for Suitable,......unless you were on fire!, Then its Captains Call, and defend your actions later.

In the case of an Emergency / Malfunction that requires an immediate landing, you are required to 'Divert to the nearest SUITABLE airport'. Departing Perth for Kuala Lumpur, 1.5 hours from Perth, your Nearest Suitable Airport is Perth. Nothing else is Suitable for a 200 Ton Aircraft.
