this is exactly what I am looking for! trying to figure out how I could make this work in an affordaplane, never the less a masterpiece of an engine!
Hi Kevin. In my book, that qualifies as a masterpiece. It looks and sounds fantastic! I'm standing by with baited breath to see how it does as you continue your testing. I'm always impressed with the level of detail and data that you include in your testing programs. Keep up the great work sir and thank you for allowing us to stand humbly by looking over your shoulder as you do.

Bob McBride thanks but bollocks Bob;-) I'm just a hobbyist trying to leave behind something that can solve the issue of Rotax price point killing off medium Aviation. The two strokes are fine for the fun flyers but I always wanted a genuinely tour-able motor. Run into an obstacle that was unforeseen, the generator isn't a permanent magnet type, so needs a battery just to make output. Disconnect battery and it stops, even with the generator output attached...now found out that isn't true, later revision on wiring diagram means battery or generator failure it keeps going
@@KevinArmstrong4154 ..and how that can be solved? external generator attached to the drive by a belt perhaps?
No need Polar Flyer. Now found by accident that the generator when connected directly to the ECUs and pump will run the injection system without a battery connected, in fact it refused to stop when switched off! Cured this by including the relay for the pump in the ignition switch circuit, and isolating the generator when stopped as that flattens the battery. Posted the new wiring diagram via Dropbox Link. Flown a number of times now, burning 7.5 litres per hour at 60mph in a draggy trike, just think what this could do in a sleek fixed-wing...
Thats a Lot of HP to work with , In a Small Package!
Reliability boost and oodles of power. Nice :)
Pretty cool bro
YOU THE MAN!!!!!!!!!!!!!!!!!!!!!!!! NOTHING MORE TOI ADD,,,CONGRATS
its the aeromarine years before the aeromarine lol
Sounds just like my lawn mower does !😁
Love it
I don't know but it didn't sound like it was running that good too me
Kevin, how are you. The reduction drive has been improved
Good job! Can you tell us where did you get the PSRU? DIY?
Designed it to fit the Briggs and this engine, made by a Brit running a factory in India, to my design. Price is low, workmanship excellent. I have no commercial tie in but he's sold a lot to others now. Ace Aviation, info@aceaviation.co.uk
Good job!
Can you tellus more on the brand of original engine?
Did you modify something except adding the PSRU?
Thank you for sharing your experiences ...
Engine is a Gaokin, bought via Copower at Wuxi, it came with radiator, fuel injection parts and wiring harness, drawing was partly in Chinese so redrew that on CAD. It's a pretty nice copy of the Rotax 800 series V-Twin
@@KevinArmstrong4154 how can I get this reduction drive for $400. I just want try it on a new plane I sm building in Haiti
@@simplyfocus9937 Ace Redrive PSRUs out of The UK. Cost closer to $700-950 USD.
You can also make your own.
@@TheJustinJ thanks
I wonder how much power it will make in the air
Look at my other videos to see it flying, plenty of go, fine pitch prop in small size still got 1100 feet per minute, and the ancillaries are way too heavy
What about carb jetting? You cruising reduced power it is going to cool way down needing a richer mixture + cooler temps up at alt. Looks kinda massive , guess it works for UL trikes
It's fuel injection, the oxygen sensors in the exhaust sense current mixture strength, and feed it back to the system. Same as modern cars and motorcycles. It's an ATV motor
Is that the gaokin 500 cc engine? What is the installed weight?
800cc, 61hp, bare engine 42 kilos, add 3 for cooling and 4 for silencers, I used lithium battery, redrive from Ace Aviation around 4 kilos
How much does it weigh? Can it pull tractor style? I would guess the bearting in the PSRU would be key to handling the thrust direction.
Redrive used for Tractor more often than pusher, Ace Aviation made it to my design but they added a huge circlip to the propeller shaft to stop it withdrawing under tension (it cannot do that anyway as it's clamped) becaue USA customers asked for it. Bearings accept thrust in pusher or traction as they are twinned deep groove ball bearings with one roller to handle the big belt tension nearest the motor.
I weighed the bare engine at 42 kilos but add 4-6 kilos for exhaust unless you are OK with open pipes, plus another 6 for cooling system and maybe 4.5-5 for the reduction drive. Mine is very clumsily designed as didn't know how much the uneven pulse of a V-Twin would shake the airframe, so added several kilos of extra supports and bracing
Which brand is it? Whats your thoughts on it? Total flying weight?
I have a B2RD t g at going to be using a 503. Is this close to that weight.
Thanks for the video
much heavier, around 60 kilos installed, more like a Rotax 582, uses tiny amounts of fuel though, around a third of the two stroke and 10-11hp more powerful
How about an update, hours ETC
Around 35 in flight, maybe half that again ground running
What engine did you use?
It's out of a Hisun HS300 ATV, made by Gaokin
The real question is how much dose the whole setup weigh?
Hi 60 - 70 kilos, those BMW exhaust cans I've used for test purposes are 6.5 kilos each, so plenty can be shaved off using lightweight motorcycle cans
@@KevinArmstrong4154 darn to heavy for a leagle eagle
Kevin, I need an engine for the Pulsar Aircraft kit I am building. It calls for a Rotax 582 but I would much rather install a four stroke . I am desperately seeking solutions to this problem. If you would so kind as to point me in the right direction I would certainly appreciate sir. Also, I need the weight to be comparable to the Rotax 582 set up.
Thank you for your time and consideration on this matter sir.
Sincerely and Respectfully,
Yellowhammer
Where are you based? If you supply your email address I can add you to a Dropbox link to all the photographs and drawings. Doing this for a hobby but happy to give any info that helps. Weight comparable to a 582 but doesn't require the big tuned exhaust, so engine heavier, but exhaust can be minimal. Just needs oxygen sensor sockets
Now sent you the link to my Dropbox resource, might be advisable to delete your message to stop companies getting hold of your email address and spamming you
Yellowhammer, if you don't mind me asking, is your Pulsar to be an SSDR or will it remain as a permit aircraft. The reason I ask is that the LAA (well CAA requirement to be fair) would insist on a dual ignition system, which rules out 4 valve engines like this as there is just no way to fit additional spark plugs into the head. If its an SSDR like Kevs, then no issue as you can fit whatever engine you like. I'm aware of at least one SSDR Pulsar.
Hi Kevin,i reallu appreciate yours videos, i'm in making a hovercraft , with a rotax snowmobile engine similar to yours, 800cc 4 strokes, electronique injection, i want to put a propeller, but i dont't know what kind of reduction drive to use ( pulleys and belt ) , and how to fix it to the engine block , and my cranckshaft shaft are taper.
The reduction drive was designed at my engineering office originally for a Briggs engine, and later strengthened to suit the 61hp or 45KW unit, which is a Chinese copy of yours. You can buy the reduction for a good price from Ace Aviation, website aceaviation.co.uk. email is info@aceaviation.co.uk and admin@aceaviation.co.uk. The factory is in India to keep costs low and run by a British man, John Penry-Evans, their workmanship and quality are excellent. If you email me can send you the drawings. The reduction has to have a clamping bush on the crankshaft so it can be moved in and out to align the belt pulleys, this needs a parallel shaft, so we added an adapter with internal taper and outside plain parallel to suit the clamping bush. The engine has two 10mm threaded mounting holes each side, and my drawings include brackets and spacers both to mount the reduction drive and fix an upper attachment for an engine anti vibration fixing to your chassis. look forward to adding you to my DropBox access link. recommend you send me photographs of your engine to make sure the mountings are in the correct place please, glad to help

Ola amigo , aqui é do Brasil.
Que motor é esse?
O motor é usado em quadriciclos ou quadriciclos, é um 800cc 61hp V-Twin, refrigerado a água e injeção de combustível. Eles são usados em Hisun chinês 4 rodas motrizes e jetskis
Which ATV? Polaris?
Gaokin, bought from Connie Chen at Copower, Wuxi, pretty much a copy of the Rotax. Others have bought from different distributors as Copower have issues with the Alibaba paperwork. I've now got translated copies of the wiring diagram and Fuel Injection plugs, thanks to son who worked in China, as drawings. Send over a private message and can add anyone wanting to follow this to a Dropbox file. So far so promising, got to rebuild the wing so someone can test fly it, but so far no overheating or oil leaks so looks good...
Fitted to Hisun ATVs sold in Texas and around the USA
