Why do a comparison test with so many controllable factors that are not matched. It really needs to be same weight of pilot on similar wings flying the same style or else the test is almost meaningless.
Precisely. Same pilot weight, same wing, same trim setting, same maneouvres. Ideally the same pilot flying a fixed course (something like climb at x m/s to y altitude, remain at y for z km, etc...). Also worth having done some preparative testing for most efficient prop size and type for each engine. Personally, I really don't think the 4kg extra weight, extra cost and concerns about battery (if battery, ecu or fuel pump dies, engine dies...) are worth it. More to go wrong. At least on a carb engine, when something does go wrong it's easy to diagnose and fix. Happy to stick with my PA125 for now, 3.5l/hr and 65kg thrust, gets me in the air. 5.7l for an hour on the Atom80 sounds off to me...
@@christanevans825 Look forward to that one. 9lbs of fuel burn is around 5.7l/hr, which is more than I burn as a 90kg pilot on my 125cc, so it seems higher than it should be.
The dealer units allow us to service clients units... We agree that it's not an ideal system but we're currently locked into what Vittorazi prescribes while they consider the right to repair laws in the US.
I’m glad you addressed the unfair comparison at the end of the video. If you have the ability to, a thrust test bench, RPM and fuel flow gauge would really give a truly accurate side by side comparison. Regardless of the above, what props were you running on both machines?
Idk anytime they show that display it makes me not want to fly it. Efficiency is great but part of the freedom and simplicity goes way from the flight with that display. When's the first one gonna throw a check engine light?
I do love the simplicity (and light weight) of my pull start 2 stroke. A little preventative maintenance and listening to what it's telling you in flight can keep it going nicely. All part of the sport for me, being the "simplest" form of aviation. I realise there are pilots who don't like being 2 stroke maintenance mechanics, though. So I guess I'm just not part of the "target market"... 🤷♂
@@stephenkeen6044 Honestly I might be interested in the 3rd or 4th iteration of this, but yea the simplicity is definitely a big draw. I'd say the target market for this will be people with excess money and people who do a lot of cross country.
Once a charging circuit is added to the design, it will be a worthy beast! Otherwise, having to worry about the battery being charged is a little bothersome. Would greatly enhance it's value.
Interesting, I am around 700C EGT when running near stoichiometric AFR with my Thor 202 as confirmed with a Lambda sensor. Curious where the EGT sensor is located on the Moster EFI (how far from the exhaust port).
Fair point, but so is a Carberettor. EFI systems are definitely more robust than carbs when designed correctly. It's quite evident when you look at every single industry involving internal combustion..
Does Aviator have a load tester that could do direct comparisons at a static load? While interesting, the video really doesn't prove anything with all the different variables.
Love the channel but I have to say this was a pretty pointless video. About as unscientific as it's possible to get, in which case why put it up on TH-cam as a comparison? This was better left for a proper video.
why even make this video, it's totally not relevant, you fly different wings, different wing loading, different pilots weight, slightly different flying styles . Change the title as it's click bite.

@@stephenkeen6044 5.7 is allot for an atom 80 for sure. Mine burns below 4L an hr I think
We did another test with very closely weighted pilots on same wing size. Keep watching! 🤩
@@christanevans825 Look forward to that one. 9lbs of fuel burn is around 5.7l/hr, which is more than I burn as a 90kg pilot on my 125cc, so it seems higher than it should be.
@@christanevans825 Same model wing also? Some wings are more efficient than others, which will skew the data also.
Wait your saying a dealer unit has more features on the EFI controller than what someone would get for paying full price for it??? That’s BS
The dealer units allow us to service clients units... We agree that it's not an ideal system but we're currently locked into what Vittorazi prescribes while they consider the right to repair laws in the US.
Why not just use the same pilot on the same wing, doing a predetermined flight pattern to try and get an apples:apples comparison?

Awesome! 👍😎👍 Even got a Fletch video-bomb.
We need a comparison on the atom 80 for fuel burn on 125cc, 130cc, and the 140,
Need a static ground test running the same amount of time and rpms
Tune in next week;)
Love the channel and the content, Subscribed. That being said, a more controlled test would be sweeterest.
Working on it!
Two different wings two different pilots two different weights two different wing loadings yeah brilliant comparisons 😂😂😂
I was thinking the exact same thing, that's not a fair comparison.
@@white7684 no where near the same comparison way to many variables that have been changed
I'm liking the gimbaled footage Reese!
Surely the only comparison worth doing is rpm over time e.g. both fly at 5000rpm for an hour?
Hey Niel, you know I'm pretty much the exact same size as you, I'm willing to test that with you.
To evaluate the fuel burn in any technical way, simply strap the motors down and run them. There is no reason to fly during a test. Its a test.
Interesting, I am around 700C EGT when running near stoichiometric AFR with my Thor 202 as confirmed with a Lambda sensor. Curious where the EGT sensor is located on the Moster EFI (how far from the exhaust port).
Fuel injection is just another point of failure. Compare EFI to Smartcarb, that would be worth watching.
Fair point, but so is a Carberettor. EFI systems are definitely more robust than carbs when designed correctly. It's quite evident when you look at every single industry involving internal combustion..
Can we buy the EFI as a kit to update the Moster?
Sadly, no. It is a different crankcase entirely.

Who put Fletch outside?! 😂
Sorry I was completely distracted by the little guy picking at his eye and scratching himself every time he's on camera...

It's certainly not scientific in any way but our team wanted to do some flying and have some fun! Thought we would share :)
@@aviator Can't blame you for that bit, that's for sure - fun is what it's all about after all. 👍
