    I saw this on a Facebook post. A fellow has created a 1/2 rotax 912 and plans to make it a kit - buy his parts and stick the reusable 912 bits on it. Similar to the 0100. Claims about 50 hp. There are running videos, but none swinging a prop yet. Claimed dry weight is 39kg (86 lbs)...! Already there are postulations of using a big bore kit for 60+ horsepower. If he has this balanced right so it doesn't tear itself apart, and doesn't cost a fortune, it will be awesome. Spec sheet attached. Links below.

    My guess it will be expensive, but the point is it will have a big market in Europe where it fits the aircraft flown. They will sell 5,000 of those on new planes of that spec if they got it right. For the US market I bet the O-100 will be less expensive in a relative way. It’s going to be US vs Europe. The economics of need are driven different.

    I very briefly pondered a '456'. Then I saw what the parts would cost...

    I've been following him on Facebook. He recently posted that he won't be producing the engine himself. He only designed it. He's looking to sell the design to a company with the ability to manufacture it in volume.

    What does that mean? It means whether this engine is actually produced is anyone's guess.

    There's definitely a market for this engine. I have no idea why Rotax didn't do it themselves. The main key to whether an engine like this will be successful, of course, is price. If it's north of $10k, it's going to be a tough sell.

    How many per year would sell?
    A 912, new, is around $22,000, so if Rotax deleted two cylinders, it certainly would cost well over $10,000.

    "I have no idea why Rotax didn't do it themselves."
    It has to do with marginal costs/prices. "Half" VW/Continental/Lycoming/et al, are not half as costly to produce. Sometimes a few percent more parts can bring in a lot more dollars in sales. Plus, what sizes are actually going to sell? We all want 4-place airplanes, but who flys with more than 2 souls on board?
    The guy is located in Arad, Romania, should one wish to spin by... :) Nice chap - replied to my Facebook query.

    In Europe they would mostly go into factory built planes for their version of light sport. We in the US think small is cheap budget. Average Europeans can’t afford anything but one of those powered airplanes. If it works they will sell a lot.

    An example is Italy. Italy has under 1000 regular GA airplanes. 172s, Bonanzas,Barrons and the like. They have 12,000 what we would call LSA. You can see where their market is loaded. The US only has 6000 LSA pilots total; there is 170,000 private pilots in the US. Texas has as many regular GA airplanes as Germany has airplanes. California has about 6000 more. One side of the pond is backwards from the other side. Our flying a 172 is cheaper than Europeans flying their LSA.

    It may be 3/4 of the cost of a 912 for Rotax to build them at a similar profit. That's not cheap. It may only have 1/2 the cylinders, but it probably has 3/4 the parts of a 912. I could still see a limited market. Rotax has no doubt already considered the idea.

    Half a Jabiru makes more sense.

    It's impossible to say how many would sell per year without knowing the price. And price depends on where the engine is produced. Many people forget that the EU adds a value added tax (VAT) onto the cost of everything produced in the region. The VAT increases prices by approximately 30%.

    VAT is applied in the country of purchase at point of sale regardless of origin. Exports attract no VAT. Rate varies according to country. UK and France are 20%, I don't know of any as high as 30%

    The market would be the one million ultralights and all the current electric designs(that are pretty dam optimized) that are being considered worldwide.

    Thanks for the clarification. I didn't know that about the exports. I looked up the VAT rates, and it does look like Hungary's VAT is 27%...

    When it comes to explaining myself, I always say that half a wit is better than no wit at all. o_O

    You just coined the name for all cut case/ cylinder engines fliers. Half wit.
    Someone with a full cylinder engine is a full wit.

    There comes one of those half wit pilots.

    It always comes down to arguments of half wits and the full wits.

    We need some hats. Half Wit Flying Club.
