You are really doing great videos for the community. Thank you.

[patthepatioguy]

Great video buddy if I wasn’t so happy for you getting to fly all that awesome equipment I’d be jealous
Keep up the good work

[doubledeeeeeeez]

Will they be selling upgrade kits? I already have a dual start my19, would like to just do a conversion and lose the carb. Should just be a throttle body swap, maybe a temp sensor, and how are they getting the 14.7 to 1 fuel mix stoichiometric ratio? Are they using a wide band o2 sensor? I thought the 2 stroke exhaust ruins wide band sensors? Curious how they managed to get around that. I think there are some 2 stroke outboards out there that were built with EFI. Might be some shared tech.

The river (bottom) you were flying over looked like it would be fun to fly through with loads of foot-drags.

[Efntodd]

Love it

Thanks for the review overview

Do you know if there will be a mod kit to go from carb to efi?

[stephenkeen]

Would have been great to see... well, anything really: The display, the overall motor and the differences, the fuel pump system, etc. Any chance of a supplemental video where you can show these things?

[Edit] Personal opinion on the design is that from what I can tell it looks like a manifold injection system, I think there can be more to gain from a transfer port injector system, but it takes a lot more development work and can't be retrofitted to a carb engine. [Edit]

[jeroend]

Awesome! I was there yesterday on my paramotor trip through Europe.🤙

[johnnyst.]

Hello mate. For how many operating hours is this engine built for?? I mean the lifespan of this engine

[ss]

Sounds like a good thing efi moster! How the airspace looks like over there by the way?

[ppgtraininguk]

Are they going to introduce it on the factory R engine?

[tschmitz]

Hey 👋 i was curious if you've had any update on the moster EFI? any concerns? I'm really interested in getting it.

[markallisonparamotor]

Interesting. Do you know what would be even more interesting? EFi on an Atom 80! What would the fuel burn be on that?!

[MitchG]

Sounds great for winning an icarus race or xc adventures. Ill keep the carb for ripping around the lz

[iKenFlyPPG]

Sounds like it's got a larger or thinner butterfly valve, basically more effective area leading to more airflow. All 2T and 4T gasoline engines have some type of air valve like a butterfly.

[vibaba]

Why is there a separate battery needed for this system? Does this engine not have a generator to charge its own battery? You did not mention it but I think it is a huge drawback. As I understand it it only lasts for 5 hours. I do think fuel injection is the way to go.

[jeremy]

Yep no carb, no jets, so should be very smooth power delivery. Would be cool to have oil injection eventually too, but that might add a bit too much weight. Not sure if we will ever be 4 stroke on these things and be competitive.

[vincentbizon]

So does the EFI have sensors to allow it to auto tune? So for elevation and all the variables that cause us problems with carbs.

[ryandinan]

Wow, a normal Moster 185 burns 4.5 - 6L/hr?? I'm still on my Nitro 200, and it has always burned around 3.5L/hr. I know it's not apples to apples, but it is nearly the same displacement as the Moster - so I'd think the fuel burn would have been closer. Of course, wing size, prop size, loading, etc all impact this.

[jackofalltrades]

Well since its fuel injected it should solve quite a few problems. Such as the adjustments needed, mid range shutter and sputter, fuel starvation issues, etc.... you know... all those issues due to the carb being manufactored for a chain saw with the duel tank only inches away vs feet away. Did you notice the lack of mid-range shutter?
