@experimentalaircraft I understand I just thought it was amusing that the price was never mentioned. I also think most westerners are not in favor of a copy but how many companies make cub clones? How is that ok but for some reason making a copy of an engine that’s been on the market for over 30 years is considered bad form?

That's not how that works, at all. This is an "affordable" 100 hp engine, not a 350 hp turbocharged FADEC engine going into a million dollar airplane. If a company wants me to "call for price", I'm definitely not doing that. I value transparency, not cheap sales tactics.

I’ve worked at an FBO and built a half dozen or so engines, mostly IO-470 & 520s. Silicone (RTV) is a big no-no. It softens in hot oil and the goobers can end up in the oil passages. That is a non starter for me.

I was originally very sceptical of this engine. We have a Rotax engine shop and when I bought the first Zonsen engine I had it stripped down to the crank and check the quality and tolerances as far as possible. With the engine stripped, you cannot see any difference between this engine and a Rotax engine. The parts were to the decimal the same size and extremely high quality. I reassembled the engine, slap a KFA turbo on it and am now happily flying behind a 135hp KFA version in my KFA Explorer. The engine is extremely smooth and performs flawless. From a mechanical perspective there is no reason for me to doubt that this one will be just as good and maybe even better than Rotax. When I sell a standard Zonsen engine it comes with a 300hr or 24 month warrantee, which is better than Rotax. This company is massive and they manufacture engines for very well known car brands (high end German and some US cars) generators, motor cycles and much more, so you can criticise all you like but chances are that you are driving or have driven behind some of their engine in well known cars, bikes, lawnmowers etc etc. Some competition in the market can only be good for the consumer.

Looking at current prices the delta isn't as much as I expected. I've used their ATV clones and they haven't ever given me an issue, the carbs have they always gum up faster, I'm not sure if its a material thing or what... the good news on the Gy6/atv is you just put your hand over the intake and crank it and it will usually open up the jets and run. Would be curious to see if their carbs used here have similar issues. 115hp is 10k cheaper and the 100 is 7k cheaper, nothing to sneeze at but... now if they can find other uses (those little cars or something) to increase volume of these types of engines it might pull the cost down for both rotax and zd. The market needs affordable engines so hopefully these have a impact. The 912/914 market is large (in aviation terms), and the IO540 is probably the next popular... that is an area that needs a good slot in replacement as most of the 4 place experimental use it and the price has become preventative for many.

Good reporting! The cost of parts is what really is the downside of Rotax. Rotax cylinders, rings, pistons cost the same as certified Lycoming/Continental. That is why Rotax engines are never overhauled because the parts cost and the labor cost from Lockwood exceeds the cost of a new engine. Rebuilding.the gearbox (childs play for even an average experienced mechanic) costs $2,800 from Lockwood. Absolutely ridiculous for what amounts to be a simple non EPA compliant motorcycle engine. I hope Zongsen puts a serious dent in the Rotax customer base. I for sure will be buying their replacement parts.

This is the same sort of crap going on in the small gas engine world where all the small USA and Japanese engine companies are competing against their own designs being built far cheaper in Asia. Our American and European companies get destroyed over environmental regulations which the Asian companies are not subject too so this is part of why this junk is cheaper. I think some of the welding visible in the video looks like crap too. They probably paint the main castings so they can butter up the rough spots with BONDO and cover it up.

Mr. Kacsmarek has a tough job ahead of him. He is very careful about using the word “Asia” instead of the word “China” and if you are not proud of where your product is manufactured that’s not a good start. He answers questions about quality and warranty by explaining what those standards and certifications mean but never clearly states the engine meets them. He points out the excellent warranty but never provided an example of how the process would actually play out for a customer. He never said if parts were readily available or in stock but in the event of a major failure, ZS “wants the entire engine back”. What does that mean for the owner? That’s no different than how Rotax does it. To me, this implies he doesn’t want to explain the details because it’s not going to brief well to potential customers. He did admit there are no service centers in the US for this engine yet but he’s working with a guy in a hangar in Florida. He missed the opportunity to explain how ZS will keep their customers informed of component defects, recalls, service or safety bulletins, etc. No mention of the technical data owners or mechanics need to service and repair the engine and where to go to keep it updated. Bolting an engine to an aircraft is about much more than the upfront price and Richard missed an opportunity to convince us the ZS is a good alternative to the Rotax product.

15:40 did I get that correctly? "Helping out Rotax owners" with non-OEM parts from a different manufacturer?😅 26:35 in real engineering, we either use RTV _or_ an O-ring or a gasket or a lip seal. These are all different design elements with a myriad of variations, so I am always eager to learn. But I just don't get why one should be happy with a manufacturer that uses RTV to "quicken" the production process to mount something that is design-wise sealed with an O-ring. This will cause headaches down the road.

For the people saying they wouldnt trust a new new engine from china (some having geopolitical tension with them) remember that uou dknt start with a name Lycoming, Continental and Rotax all started where Zhonshen is now. If anything, Zhongshen is starting from a better place because they're starting from a place of advanced knowledge. Rotax had to prove themselves and now theyre revered, give these guys the same chance.

I love all of the comments about chinese garbage, sure with some things but China also has manufacturing capabilty and quality that rivals North American. It all depends if you want the 50.cent Chinese product or the $2 chinese product. Isn't Continental Chinese? How many other aircraft companies are now Chinese owned? How many parts do you think are sent over from China like he said but built in America? Tons. Make a judgment on the product and not your complete speculation! Aircraft engines have increased 100% over the last 6 years, I can tell you the metal components haven't increased to enough to justify that increase. They are gouging consumers because they can, making record profits. 60k for some of these engines now with 75 year old technology. I hope more competition comes into the market. The engines are made for a fraction of what they are sold for and the current environment has stifled technological advancements. Maybe if they start losing some business it will force these manufacturers to stop raising prices and start developing some newer technology.

Not every engine failure leads to a crash. There's plenty of issues that can be just a "take note of that and fix later" type of thing - even noticed on the annual inspection. All a warranty is is a matter of the maker's confidence in the engine. A long warranty puts them on the financial hook for repairs so if they don't think it'll make it that long they won't warrant it for that long.

Since there isn't much competition, is that how prices are so high? I don't know but they seem high priced to the point that even pt 103 planes are hard to get going? I'm only asking - only way to learn and I am glad to hear this interview. I like replacement of motors & strict standards on nuts/bolts & parts. peace

Several factors. One - there just aren't nearly as many planes built as most other stuff. If you'll look at the total number of any specific model built its probably less than the number of Corollas Toyota sells every 2 weeks. A more niche product will always cost more. If more people were flying and we were building more aircraft (and aircraft engines) the price would be lower, but currently aviation is extremely expensive so not as many people can afford it. Chicken and egg problem. 50-60 years ago they seemed to be building more planes and they were less expensive adjusted for inflation (often 1/2 to even 1/3 the cost of a new plane today when adjusted for inflation). Secondly, many/most countries place some serious regulations around anything that goes into an aircraft. Even outside of engines and just on avionics/electronics if you look at the stuff for certified aircraft versus what can be used in an experimental, its about double the cost for certified. That has also lead to the increases mentioned in point #1. And then there is just the realistic bit that most transportation engines like car engines have short bursts of higher RPM while accelerating and then downshift and can keep the car moving at a given speed at a much lower RPM, working the engine less hard. Airplane engines tend to be running high RPM constantly during flight. That just is tougher on an engine and requires higher quality construction and engineering to make it reliable.

I realize how dumb a question I asked & of course I realize not many planes are built but what I was thinking as I said this is that it seemed to me the big Japanese motorcycle/outboard & car giants are barely doing any & again it's all about so few being sold but I'm surprised they've not tried. I think I saw some Yamaha Air Craft motors, I think? I'm watching lots of boating/motorcycle building videos so as I jumped over to planes I'm behind the ball trying to pick up a lot real fast. I do appreciate your teaching me here, it is why I ask & prices are what keep me from trying to get into it. Probably smart for me to stay on the ground but I enjoy watching these guys/gals chasing the dream & money is part of it all, just more of it. And after what you've shared, that must explain all the older planes in operation? New is super high priced & used at least is built, redo things as needed & you can fly. Yeah, I'm only now realizing why there are so many pre-2000 built planes. I wasn't too sure but I see it now. Thanks

I have purchased products that came out of China , as they are becoming more available in the current market place here in N.America and probably throughout other places on our planet... Several of their products seemed to have initial Q.C. and questionable materials issues, when they first became available... Now, the Chinese products have become quite reliable and definitely show impressive quality with attention to detail... This engine is one of those.... BTW, the Chinese Products are not the first ones to clone designs that were developed in oyher countries... There are numerous sucessful countries who cloned products that came from other parts of the World 🌎🌍... I'm wondering what the specific materials are that are used to produce these engines : What alloy type was used for the high- stress castings (like the center cases, psru cases, heads, cylinder jugs, Pistons, etc.) ? Were these parts checked for cracks, inclusions, air pockets, etc, ? What type of metal was used for the high-stress steel components (like crankshafts, camshafts, connecting rods, valves and valvetrane component's, piston rings, connecting rod bolts, center case and jug studs, etc.) Are the 2-piece con-rods the fractured type or the machined parting - surface type? What is the primary triggering device for both of the ignition systems? Points & electronic ? Maybe a medium voltage 'Scintilla' 'shower of sparks' type with points? Do the ignition drives have inpulse couplings ? Are the Ignition leads the standard shielded type? I'm a BIG fan of carburetors... Those look like clones of the CV Bings... I especially liked the anti-ice intake collars that looked like they transferred the heat from hot oil to keep the Air horn impact air porting, venturi slides & throttle place free of ice... What are the specs. of this machine? Can the parts supply chain travel from other places, besides China? I'm also wondering about the manuals... are they readily available for these engines and associated equipment like the props, ignition system, induction system, exhaust systems, engine oil cooler heat exchangers and thermostats, electrical power generation and cranking systems ?

All these water-cooled, alternator and battery dependent engines would work great in snowmobiles, ATVs, or PWCs, but I really do like air-cooling, carburetors, and magnetos in airplanes. No worries about coolant leaks in flight and it keeps running normally with total electrical failure. If these things are the future of aviation, I'm done flying. Electronics might be durable, but I've seen a lot more alternator failures than magneto failures in my 42 years in aviation, and when the battery gets weak, electronic ignition or FADEC just stops working. Backup batteries don't make me feel any better about it. One more thing to add weight and require maintenance, which means one more thing to get neglected. Aviation R&D is going in the wrong directions.

The Chinese government allows espionage to take technology from countries around the world. They also do not in enforce worldwide patent laws. So it’s typical for clothing and manufacturing items to have exact clones or knock offs made in China. Often on the same factory floor.
