Review - EOS Quattro 4-Stroke Paramotor Engine - Fuel Consumption, Weight, Likes and Dislikes.

What an amazing engine! The EOS Quattro burns half the fuel of my MY20 Moster 185 dual start and more than half the fuel of my Moster 185 Factory R! It makes more power than the standard Moster 185, and it’s whisper quiet! In this video I have an amazing flight over Pocatello, Idaho with the clouds cascading off of the mountains! Check it out!

[@SeeCoryRun]

Thank you so much for this comparison! Especially the actual flying weight considering fuel consumption amounts, the weight really comes close to balancing out. Between not mixing fuel and low maintenance this seems like such a win win.

Nice comparison between the factory R and the EOS, I currently have a MY19 moster, and an air conception dual start nitro 200. And I’m going to Florida end of this month to get my tandem exemption at one up adventures. Cosmos 300 is my next purchase on a fly products strike

that's it, i'm getting the EOS. I'm so done with dealing with twostrokes it's either this or going electric, but electric is too heavy and doesn't have the range.

[@trentwhitney8346]

[@Hyperious_in_the_air]

honestly something is wrong with your carb high-jet settings if you're burning more than 8l/h on any Moster, even if you're heavy on a wing at altitude... For reference, I'm on an MY20 with a 24M wing, and overweigt range by 20kg on the wing, and still seeing only 4.25l/hr at 3000ft launch

[@CalebJohnsonlivingca]

Unless he's just wide open throttle for most of the flight.

[@trentwhitney8346]

Think about taking off in a 777 with the engines of a 737 and at higher elevation. Both planes have pretty much the same wing loading. They will both glide fine if the engines quit. If the 777 could even get in the air it would be at full power all the time. And burn a ton more fuel. This is across the board no matter what engine I fly. It’s the trust to weight ratio. I’m in the top 1% of all pilots for weight and I fly from high elevations. If wing loading was the only variable we’d all be on Atom 80s. Your cruise for level flight is likely 800-1200 rpm less than me. I need 5900-6100 for level flight. That alone will burn significantly more fuel. I also fly in the mountains.

Great review, you covered everything I could think of, I’d be keen to see how long the Eos lasts and what if any problem it has over the coming months. The sound of a four stroke is so much nicer and less intrusive so it’s hands down a win, as long as it has the reliability, something the the Eos 150 didn’t have..

[@trentwhitney8346]

@@trentwhitney8346 I freaking HATE 2 stroke engines. How is the 4 stroke holding up for you? Im only 125lbs and fly a moster. LOVED my atom, but simply didnt have the power. Im wondering if the quattro is a viable replace for the moster. Not diggin the extra weight (4 lbs?), but I bet its offset in fuel savings for the most part. Keep us updated, I REALLY want a 4 stroker to be a good option.

@@trentwhitney8346 Interesting. I guess being a 4-stroke, doesnt have as much benefit as one would hope. Damn. I really like the idea of a quiet, gas sipping and smooth motor. If the eos was ALL of those things, you'd still have it, tis my guess.

[@johanvantonder4642]

Hi Trent, Great video, thank you for all the good information you provide in all your videos. I am about to get into PPG and are looking to start buying equipment. In your opinion, would the EOS 4strke be a good choice for trike flying ?

[@trentwhitney8346]

Awesome thanks! It depends on your elevation and weight. If you're as big as me (6'2" 245 pounds) taking off at nearly 5,000 feet above sea level, I would consider a Factory R or Polini 202 on a trike due to the extra weight. If it's a dedicated trike then the Cosmos 300 or Polini 303. If you're at sea level, you can use the standard Moster or EOS Quattro with no issues with the added weight of the trike.

[@CoyoteOne]

Now I wonder how it would stack up against the Moster new EFI. Thats going to be the next comparison.

[@jeffmcdonald8373]

Any updates on the Quattro? I've ordered a Cronus with a Quattro and a Colibri trike. Should be in by the end of January. Wing won't be here till end of February or first of March. Getting the Apco F5. Just curious if you've had a chance to put any more time on it with the cold weather.

[@trentwhitney8346]

Yes! I've flown it several times in the cold and snow, including on New Years Day. It's been awesome! I climbed up to almost 8000 feet that day.

[@manueleugenio8500]

Wish i could fly this

[@joshperryppg]

Interesting numbers. The factory R just drinks fuel. I've been flying my nitro 200 for 5 years now, and my average fuel burn is 3.2 to 3.5 liters per hour flying a 24m at 310lbs all up.

[@trentwhitney8346]

In my experience, everything I fly drinks fuel up here. My cruise RPMs for level flight are typically 6,000-6,500 where I fly. I’ve only occasionally dropped down to LZ’s that are about 2,000 feet above sea level and my cruise dropped to 5,000 - 5,500 rpm which would be considerably less fuel burn.

[@jeffmcdonald8373]

Great video and information. Where did you purchase the Quattro? Was it an option from Power2fly? If so what is the cost difference between it and the Moster 185?

[@trentwhitney8346]

Contact Boise Paramotors and Zman can get you accurate pricing. I think mine was only $200 more than a Moster 185 dual start on a Power2Fly Cronus.

@@trentwhitney8346 Thanks for the reply. I've gotten in touch with Darren at CarolinaPPG and he's quoted me some prices. Now to decide which way I want to go. I'm really leaning to the EOS.

Nice video Trent, I’ve been flying the 185 Vittorazi for around 6 years own two setups both have mild torque on throttle but definitely noisy and vibration is some times to much love flying long flights when i take them out also have been Paragliding for a few years and the nice thing about paragliding is the quiet and no motor vibration. So how much torque is the Quattro putting out more on torque then the 185 ? Thanks

[@trentwhitney8346]

Yes! The EOS is smoother than my 185 and much quieter. If I want to go out and rip around I prefer the Factory R. But I just added a cruise control throttle to my Quattro and it is a dream to fly long flights. Quiet, smooth (especially with a 3-blade), effortless when cruising and the throttle is linear. Want to go upside down and roll? I prefer the Factory R.

Correct. I did not change anything else. I would consult with EOS regarding your elevation and density altitude.

[@mike413]

​Flying mainly at sea level up to 1500ft. Main jet in use ( standard) is 130. But never reached 8100rpm just being at 7600max and consumption is about 3,3L/h on Dudek Hadron 3 22. My weight might be similar to yours.

[@trentwhitney8346]

@@mike413 I would gradually step it down. Fly a 128 and check your plug after a couple of flights. Then see if you need to drop again. Are you flying a 140cm prop? If yes, I'm not sure they get to 8100rpm. 7650 is the best I ever saw and typically 7300 max at my elevation.

​Flying a 130 Prop developed especially for Quattro to reach 8100-8200. Last time when I was checking Plug it was brown with direction to dark brown. My assumption was it can go leaner.

The EOS Quattro has 30.2 horsepower. The Moster 185 has 25 horsepower. The EOS weighs 19.8 kilograms compared to the Moster 185 dual start at 15.6 kilograms. But loaded up with fuel for 90 minutes of flight they are super close because you’ll carry less fuel in the Quattro.

Good stuff! It’s super easy. Flip the carburetor upside down, remove the three bolts that hold on the bowl, remove the bowl and the jet is the highest point. Unscrew it and put in the next size. Super easy, and I had never done it before.

I will take a 4-stroke over a 2 stroke any day, much more reliable, better fuel economy, no fowled plugs and if you have a 4 stroke on a Trike, you can get a Fuel Injected motor that never needs adjusted for altitude changes..

[@ChocPretz]

Any chance you could take a decibel reading of both motors at idle and full power?

[@trentwhitney8346]

I'll see what I can do. At full power its as loud as anything else due to the propeller tips approaching the speed of sound. At idle it's about as loud as anything with a muffler. It is whisper quite at cruise power and a small climb, or flying over people/animals as long as you're not at full power. Probably so stealthy due to the frequency of the muffler and due to the fact it's pointed straight in the air above you.

[@reinerressel975]

It’s simply impossible to burn 1/2 the fuel with a 4 Stroke engine . Your 2 stroke must run way way way to rich in part/cruise power .Fouled spark plugs tell the story . The air fuel mixture is approximately the same on both engine types , mor on the rich side with high power setting’s on the 2 stroke .
