I bought one of these engines at Oshkosh 2022, waiting on the wiring harness to get modified as an aircraft harness and I still need exhaust, radiator, engine mounts, the list goes on! But it'll be installed on a slipstream and if it works out, I may try putting one on my MX Sport.
I've always wondered how the uneven power pulses from a 72 degree V twin affect the drive train and propeller. I guess the PSRU and belt dampen some of that out...
Custom reduction drive good for 90 hp.... is this set-up now at 90 hp or is the drive just good for a more powerful engine than it is sitting on? I remember this V-twin being 61 hp or so before, is that still the case? Love the Merlin PSA and can't wait to try one with the V-twin!
Well the amount of force required to tension such a comically oversized belt is the culprit. These engines were designed to mount to a precision transmission. Not to be side loaded with that belt tensioner.
Direct from factory no testing straight out of the box... basically a Harbor Freight special if you know what I mean. Everyone else doing conversions is at least blueprinting every engine and making sure they are to spec.
Sure would like to see some good clear pictures of instrument panel layouts. On the Merlin site they show an eight and a half inch mgl display is available just wonder what other instruments you put in and if there's room for their VHF control head don't like everything going through the efis
Add a small turbocharger to that V-twin get high altitude performance. Lot of aftermarket turbocharger kits for those Side by Sides might be one already made for it. One of the drawbacks of 2 strokes can't add forced induction.
You can , my snowmobile has one , Polaris 850 patriot boost google it , it’s for riding in high altitude the turbo compensates for altitude so I have all 175 horsepower at 3000-4000 feet as I do at sea level .
Funny coincidence...my first car, 2 door 800 cc , 60 hp , 4 passenger, fiat panda 1987 , at this point I can convert lots of engine....maybe not,...but very interesting solution 👍
If its an 800/850 by GK Gaokin, its torque is very flat from 3-6k. Peaks around 4-5,000. Same RPM range you will find 75% power. Red-Line is up around 6-6,500. Peak power is 6-6,250.*edit There are now multiple redrive/PSRUs available on the market for around $1k each. The basic motors are $2k from china, plus international freight, customs, wait time, and might not get what you wanted and probably cannot return it. So, these small companies who offer the product complete offer a lot of value vs doing the dozens of hours of leg work and CAD work and CNC machining yourself.
Chip sent the the modified wiring harness, I think it was just a proto-type as it came with no tubing covering the wires. Also had an issue with one of the wires ( a brown one, not sure for what ) was cut and missing about 1/3 of the copper strands. I think their testing guy may have forgot to send the regulator 2 pin connector that connects the regulator to the battery, may have left it connected to the test stand, and the cut wire I'm sure was from wiring an entire harness for aircraft. Anyways, talked to Chip today and he's sending me a new harness when they come in ( First week in December?) So should have the connector with that and I'm getting a new regulator (will send mine back, it works, just had a little road rash, didn't know it till we opened the packaging) And lastly, I finally found the Make and model of the engine and a web site that sell parts, though not as good as what Merlin has. I'll have to modify the exhaust, not sure the muffler is the same (it could be) and the fuel pump is definitely not as good as the V-twin style Chip sells.
Well the amount of force required to tension such a comically oversized belt is the culprit. These engines were designed to mount to a precision transmission. Not to be side loaded with that belt tensioner.
The engine is a Gaokin 800cc v-twin (no through-shaft) and can be had for a little over 2k if you order from suppliers in China. The redrive is from Ace Aviation and costs about 1k + shipping. All up you'll be in a bit over 3k for this powerplant if you can sort the ancillary fixtures. There are a few struts that you see at the top of the redrive that I believe you'll need to make yourself or have made.
@@fhecrewdavid You said it completely right. I did a 850 already some time ago and now working on a 1100cc. Both from Gaokin. For the 1100cc I am doing forged crankshaft and rods, 11:1 compression ratio, 3 angled valve seats, smoothed ports and tuned exhaust and admision for 5000rpm. Internals and new flywheel dinamically balanced and taking into account the properller inertia. Piston rings are cheap, go for a gapless totalseal replacement. Using an epropeller starter/generator system so I can save weight have a better generator for avionics and some additional power at takeoff. Using a geared inline reduction and microsquirt ECU. Nice engines but I wouldnt use them without blueprinting them first. Base engine when buying it without gearbox, ECU or injectors is 1900 USD shipped, dont remember FOB price. With the right setup you can be doing 80HP@5000rpm which will be power cruising setup. As good as a 912, 20kg lighter and at 1/3 rd of the price. But you have to do your own work to get it working right. Turbocharging is really tempting but I would only do it for keeping the power up to a desired FL... since this engines doesnt have piston oil squirters or good enough cooling to overcome more thermal load. I am considering yes to modify the oil pan to increase engine oil and improve cooling and oil degradation time.
V-twin vs 582? I'm thinking heavier instal, more vibration (unless it's even heavier with balance shafts), looks like single ignition, and less power... Better get in on the 582 stock before they all go.
I think if you factor in two or three hours endurance worth of fuel into a combined propulsion mass, you will always find four stroke, EFI to out perform Two-Strokes for power/weight in every case. Then consider on a long trip you must also bring two-stroke oil to mix into your fuel, this additional weight must be brought due to the fact no FBO along your route supplies it. A Rotax 582 is a good snowmobile engine converted to UL aircraft use. But its a 1980s concept that pre-dates Multi-point EFI/ECU control. This setup, as proven by that one genius tinkering Bloke from the UK, seems to have a lot of merit for this type of use.
Dan, I looked at Aeromarine's website found the V-twin on the site but found no technical information on the engine. So I called the phone number and got Chip, I tried to get some basic information on the engine I was told "It's all set up for the Merlin." When I said I was not building a Merlin but was looking at the engine for a different design it would seem I was hung-up on. I called back and no answer after a 6 or 7 rings I was pushed to voicemail, it's been over an hour and no call back. I could be wrong, but this strikes me as Chip is not interested in talking to you unless you are building his designs when it comes to the V-twin inspite of what he was saying in the video. If Chip gets back to me I'll update this.
It's too late to complain about it being made in China. If people would have said no to China 30 years ago we would still have American choice but that shit has sailed. We are all to blame.
@@billmoody823 easy to guarantee quality by converting an actual can an engine instead of using a chinese clone. No boat has sailed . Hope the little plane glides well just in case.
You can use whatever you want. A CanAm will cost Three times more for similar design. And they are all made in Mexico. No mass produced components are made in the USA, the EPA, OSHA, Unions, Lazy Fat Americans and College Professors killed the factories. An alternative that is assembled in the US is a Briggs Vanguard Marine EFI is a contender. Its rated 40 gross hp @3600rpm but red lines at 4,800 operates continuously at 4,750. Probably makes upward of 50hp.
I work for a Polaris/CF moto dealer and this engine looks identical to a CF moto UTV 800 engine. I've been seeing a lot of premature wear issues with them, but at the same time I'm finding a ton of fine dust and dirt in the intakes. It's a very dusty environment here. Having gone through a couple of the engines though, as someone who's built a lot of motorcycle engines you can see how little care was put into internal finish of the ports, valve seating and timing components. Built to a low price point..

There was a little bit of me that was whispering 'start it , I want to hear it' .... bitterly let down lol Great video though.
You can hear it on Kevin Armstrong's channel. He's got one installed on his trike. th-cam.com/video/H8DUerJxirc/w-d-xo.html
I just had to be the first to say how much I enjoy learning about aviation from your channel …!
Everyone Loves Chip Erwin!! Legend!!
thanks Johnson for sharing this great video
Very nice, fits the bill, got plenty going for it, ideal in most situations 👍
Nice 60hp and showing telling, keep on showing telling them I might buy one never know.well thanks see ya next time see ya by

MX Sport II ?
My Grandfather (born in 1898) built a single seat monoplane in the late 1920's powered my a motorcycle engine!
So this looks very familiar to me.
How much does the engine weigh?
What does it weigh?
i ran my harley davidson engine test stand at sun n fun few years at forum white tent engine area. it was pusher! Mr.Cox put it in sport aviation mag.
Can you supply one in a pusher configuration for the Challenger II?
I've always wondered how the uneven power pulses from a 72 degree V twin affect the drive train and propeller. I guess the PSRU and belt dampen some of that out...
It's 80 degree, very snooth at high revs
Chip didn’t seem to be his chipper self today. Lots to do I guess. Great engine.
Will you please SHOW US the left side and back of the engine !
This meets ALL my criteria, thinking people
What a great motor package for many different applications . Is the reduction drive a cog tooth belt type ?
I just kept picturing a old Harley Knucklehead hanging off that mount with a similar Red Gear. Hmmm.
Wheels through time have a plane with a harley engine in one of their videos.

So inexpensive a lsa twin if allowed would be possible. Kitfox twin how cool is that.
I've had some experience with the Cuyuna belt reduction system, and they had high breakage of crankshafts. Side stresses.

Does it run at an acceptable operaturing temperature in a pusher (trike) configuration?
Mine does, oil circulates past water pump so reckon they exchange heat there

What name brand?
Does this have only one spark plugs per cylinder and only one ignition system?
Yes.
@@ultralightnews does it also have a generator or alternator? Thank you for info
These it has an alternator.
So, at 60 hp with a reduction drive, what is the HP at the prop? Thanks.
If you know the reduction ratio then HP = Torque × Rpm\5.25.
