How did you make that dashboard light up the lettering by the toggle switches?

Hey Tim. Being thinking of replacing my Jabiru on the my legacy Sonex. Mind if I mail or text you with some questions. I know the sonex B is a little wider then the legal y so my concern is mounting that beast. Look forward to chatting with you. Mark

If you don't mind me, is your aircraft flying, how many hours do you have on the engine now and would you recommend that engine for someone who's looking for an engine for an aircraft?

any updates? I'm just getting close to buying an engine for my Dakota Hawk project and was looking closely a the aeromomentum.

Any updates!? Was looking to update my Jabiru 3300 in my Sonex

Can you post an update video? This looks like a really good project.

Absolutely love your customization, please update us with more videos.

Any updates?

As a fellow LI'er, I'm guess that you're at Bayport Aerodrome.

Nice setup. I like the instrument panel you made but it looks like it may have reduced visibility over the nose. Also, where did you get the engine mount for the AM-15 from or did you have to make it yourself?

How much propclearance will you have?

how did you make that switch panel? 3d printed?

Awesome man!! Keep the videos coming 👍

thats awesome bro!

Excellent!!!! Congrats!!!!

That’s so cool. Congrats for first taxi.

Aeromomentum engines are very appealing to me. I agree with every design choice I’ve ever heard from Mr Kettering. I’ve enjoyed following your project on various platforms and hope you are smiling large at 7000 feet real soon 😎🎩♠️

Feel safer with a 40amp nippondenso alternator on there. 20 amp is kinda low...

Hey tim.....just wondering if you got the plane flying and what experience you have had with the am15??

I assume you still have to install a muffler. It must be a southern US airplane, for I do not see hoses for a cabin heater. It is very important for Canadian operations. I started on a Z750 several years ago, and now with the Sonex high wing coming, I might abandon the tail and switch to the Sonex. The Z 750 is just too slow.

Good setup!

Any update on your sonex?

What is the verdict, I wanna see you put some hours on it :) ... We are planning on rolling the dice and giving the AM15 the green light for our zenith build. Hope all is going well!

great set up. love to hear an update ESPN the AM15. did you weigh the engine yourself? qhat ECU? can you adjust/program it?

What were the benefits of this engine that made you go with it over the Jabiru? My understanding is the horsepower is basically the same.

Hi I was wondering if your Luga came yet? I have been waiting for my Luga 16 months. Did your mount your warp drive prop yet? By the way your sonex looks great!!

What about the engine cowling? What does that look like?

Are you flying this yet? If you do, how is the performance and fuel burn?

Nice! Curious about the upper engine mount and engine g loading, without triangulation. Looks like the top mounts have extreme leverage.

Thank you for posting a detailed video for the engine, any new update for the engine because I am looking to buy same one? Thank you.

Who did the motor mount?

I like these engines way better then aeroVee never trusted VW engines tinkered with them in the 80's and 90s they always leaked and eventually overheat. Just a fact you don't see air cooled engines still being used today in any application except aircraft. While certified engine builders have worked out all the bugs of air cooled engines they cost 25-50k. The only thing holds me back from the sonex is the location of the fuel tank I know lot of older aircraft stuck the tank behind the engine just seems dangerous to put a tank of fuel behind a hot engine your sitting right behind it.

How long did it take you to complete this much?

looks neat! what would be the installed weight including the radiator, oil cooler and all other ancillaries?

Hey man, I was wondering if you had the external engine dimensions. I want to see if one will fit in a reflex lightning bug. It's got a really small cowling lol.

Are you going to go with a fixed prop or constant speed? Also curious on what version and specs you are choosing.

Beautiful power plant and all of it makes sense. Sonex queation: can one build with side sticks should they want?

What is your FWF all up weight with all fluids ect.? What reinforcements were made to firewall and internal structures if greater than Sonex's recommended 200 lb max FWF weight?

Wish I could afford a sonex I already live on an airfield but just cant afford to fly it's sucks

Awesome engine!

What propeller did you order? What length? How many blades? Were you able to calculate an expected top cruise speed? Thanks. I'm very close to placing a deposit on an AM13hHP @ 126hp. It's for a Skystar Pulsar III which is very similar size and weight. Your project is inspiring!

OMG just listen to that ECU-controlled, EFI, high energy electronic ignition, multi-sensor-monitored, precision internal toleranced, high performance, affordable, low maintenance, high reliability, liquid cooled powerplant!!! I am SO DONE with crappy carburetors, low energy ignitions that require spark plug gaps at 0.022", inefficient air cooling, self-destructive EGT and CHT, dangerous exhaust muff cockpit heaters, etc. The only advantage to traditional aviation boxer engines IMO is the form factor is easily accommodated in most aircraft cowls.

Looking forward to seeing what size and type of propeller you install. I'm pretty sure this engine installation requires the prop shaft centerline be placed about 2-inches lower than Jabiru, Rotax, UL Power engines. The AM induction system just sits at least 2 or 3 inches higher above prop centerline. This is a concern I have for going with AM on my Skystar Pulsar III. I apologize for hijacking your video-- right now your project is by far the most exciting and encouraging one around! Thank you for sharing!

Sweet! Looks and sounds great, can't wait to see it fly. If I ever swap engines, one of these is on my short list.

Have you attempted to fit the cowl and estimate how much modification is required?

Great progress. Question on your engine mount. Did you order from Sonex or was it custom-built for your AM15? Thanks. Let me know when you will accept visitors to your build. Am a potential Waiex purchase.

Thanks for the vid!

Will the AeroMomentum fit under the standard Sonex cowling or will you have to make significant mods or a whole new cowling?

I like the backlit instrument panel where the switches are mounted! Did you make it or where did you have it made?
