Edge Performance | Yamaha Rotax | Engine Week 2020 

You took me from zero to hero about EP in 43 minutes, great work. I wish if you keep us updated about Thomas's SLING TSi with EP 300 engine. It would a different beast as compared to the one with Rotax 915 is.

I'll be watching this one again and again. Am very seriously interested in the Epex 150 as a replacement for the Jabiru 2200 in my Skystar Pulsar III. I hate carburetors.

Edge Performance makes beautiful engines. Had my eye on these engines for years. Wonder how the Yamaha would perform in a Long EZ.... hmmm

You’re doing a great job of reporting solid info for this growing segment of fun flying! Having been closely involved in UL and kit planes for 60 years I still think light and slow is where the most fun and safety lies. Thanks for your service👍🇨🇦

Awesome vid. Thorough questions. Frank honest answers. Refreshing to see. No misleading fluff. Would have liked to hear how their redundant systems offerings are coming along. Thx for doing this! Cheers.

I really liked the commentary in this video. Well thought out, well planned, well executed. Your getting better. I like listening to you talk, it is in a soothing, not harsh manner. It still gets the point across. I think this interview is the best one you have conducted to date. Keep up the excellent work. I look forward to your next one.

Would love to see Thomas Hauklien does his magic on the Yamaha Phazer. A ready to bolt-on conversion with all the auxiliaries are sure to have a market.

Great video, this is the best info on the EPEX 300TI, I've purchased one and am waiting for it to arrive. This really helps with comfort and understanding.

Thank you so much for this amazing interview!

Thank you for the interview. I was looking for it for a long time. Much appreciated

this is important thing at the aviation engine, Light ,tough, efficiency, Yamaha engine has everything of this !

This is the one I've been waiting for all week

Hey Bryan, excellent series! I’ve been watching and researching all power options for the CH750 SD. I’m NOT stuck in the old school horizontally opposed paradigm but rather favour the Viking packages. Better designed internals in the Honda engines hands down. Liquid cooling is a must up here in Canada. No need for Carb Heat or Mixture in the 21st century. So, would it be appropriate for you to respond to me if I can solicit YOUR opinion as above? In my opinion, Viking is best and most cost effective initially AND going forward! By the way, I love your channel, you do great interesting videos!!!

Thank you very much for your series. Not a flyer, but a big fan. Looking to learn everything that i can, so find that the Experimental Aircraft Channel is very helpful! Thank you.

Thanks Brian. I have heard of Edge but knew 0 about them. Great questions, and info.

This has been a great series. Thanks very much!

Type certificates? Would it be possible to replace a lycosaurus or contirex in a usa certified pvt cat aircraft with form 337 or stc?

Nice info from edge performance. Working on a Heli project here in Kenya. Will visit in future after I succeed.

Two EPeX400Ti on a Ravin 500 or Velocity V Twin is = game over!

Great interview Bryan and Thomas, thanks!!. Lots of interesting information provided. I would love to see and visit Edge Performance 's new facilities in Norway some day.

It’s interesting to see how new ideals and developers change their production procedures after looking twards certification! I feel we should make the pathway to certification more streamlined as far as writing the ASTM building procedures. Templates and directions from the FAA or from the EAA would be extremely helpful for the new enterpreneur’s entering the Aviation Industry.

Awesome motors and I’m sure they build them top notch but man those prices are a tough pill to swallow! It would be hard in my opinion to lay out that kinda cheese for something like that when I could stick with a legacy motor like the lycoming thunderbolt for the same money. Definitely interested in a Yamaha conversation for my zenith project though. Always been a big fan of Yamaha. I own several Yamaha motorcycles and have rode and worked on them for years and can attest to there ruggedness and reliability. They have always been leaders for innovation in the power sports industry.

A great and informative interview. As an Automotive Engineer and performance engine/stroker engine builder as a hobby and used to fly back in the day. What surprises me is that EFI and associated electronics was not used sooner on experimental aircraft engines due to the fueling benefits over carbureted engines etc. Looking forwards to the rest of the engine series videos and keep up the good work.

Great video, thank you both for sharing.

They do what the facotry doesnt….. They “Race” tune the motors. They are a Master Engine Tuner service with their own upgrades! Like the JEGS of the Aviation world!

I'm retired ,&would be glad to put thousands of hours on any Engine from EDGE PERFORMANCE,,,!!-♡ 《PASS IT ON-tee-!!!☆☆

Superb interview; love the deep-dive into the fundamentals of both the mods and the business.

Very informative, any new engine developments at a good price is always interesting.

This was by far the most interesting episode, next to the Viking engine. The rest, moah (meh :-)

Awesome interview. I’ve been really enjoying your engine wing.

What a timing! I bought a Long EZ Project in November, and just last week, I saw a Yamaha snowmobile for sale, for just $1,200. Now the snowmobile is mine. Edge Performance project: here I come! Not the first time here on the channel, but I realized I never subbed. Sub gained!

He should look into the yamaha mt07 motor is not already for the smaller planes. It's on the FZ and the Tenere and is an actual game changer as far as engines. We need more engines for the little guys

19:43 Fully dressed engine sub-200 lbs!? 25:05 If heat is an issue (and when isn't it?), what about water/methanol injection? It would be an easy add-on w/ the existing fuel injection system and not terribly difficult for the carbureted engines, as I use this type of system on my air-cooled Corvair engine, w/ excellent success - aka: zero pre-detonation/knock.

Being in Australia I'm also very interested to see development of an engine utilising the Yamaha WaveRunner block. 1800/1900cc of capacity would surely be great for 4+ seater planes like the BearHawk 4&5. Has there been any development on this?

Sorry again Bryan for playing catch-up on your series. Great interview with Mr. Hauklien so the next time you speak with Thomas ask him why my Norwegian friends call me Mr. Kukien Man? lol. It’s funny how Rotax borrowed Edge’s ideas for their next series build. I wonder just how many design changes were borrowed from Edge’s designs? And I wonder if Edge is performing Rotax’s R&D for them. Edge has setup their build & test process quite professionally because they are combining engineering & manufacturing, material sciences and destructive testing to provide the aviation industry with leading performance. Thomas and their team at Edge have taken good designs then pushed their limits to new boundaries. We can see how they are going to be leaders in this industry for quite sometime now when you see the Mr. Henery’s of the world installing their designs and beating out the competition as if there is no competition! Everyone is now playing catch-up in the STOL competition and making changes to their aircraft designs as we speak. Hey that’s not fair Steve has too much advantage!

What aircraft is Thomas building? I am curious to see their site as well.Thanks.

Learned a bunch, great show.

Hahaa somebody hated under the cowlimg on a 172. This setups neato!

Let us know when you resume this series with Aeromomentum and MW Fly' including the real weights demonstration.

Make us a 4 stroke replacement for the now retired rotax 582!!! ( but with a little Edge like 80HP )

What a fresh and knowledgeable guy compared to Lycoming and Continental...welcome to 21st century.

Great job guys awesome video, yamaha makes the best engines in the world.

Wow what a Amazing review and story is amazing

The gear box on the 915 is heavier because they've had some gear boxes on the earlier Rotax's crack out and leak oil

Hi , it looks like Sling aircraft is gaining some traction/interest in Europe and that is really good for them as l also live in S Africa and like to follow how they are doing {I wish I could afford one). The question now is which engine are u going to use and that should be the interesting part...let the world know how your build progresses and finally how it performs . Good luck with the rest of the engine builds and improvements as the power ratings sound pretty amazing !

They don't state any specs on the edge website. What RPM are they running at the power output etc?

I have an early model Rotax 912UL and all you say applies to mine. I wonder if your fuel injection system works on these older models. Very interested.

Great interview. My only worry is that the Epex is no longer in production. I'm sure the Nordics will be looking at the newer Yamaha platforms.

I've been dealing with Automotive and automotive power plants for a long time. Since the mid 60s. I like the idea of learning about aircraft and their engine performance. The problem is is nobody but nobody have I ever heard talk about the actual engine performance. The only thing that they say is that the engine might put out 110 horsepower or 130 horsepower or 150 horsepower or 180 horsepower or 300 horsepower. Horsepower is not the only specification that is needed to know about the capability of the engine. You need to know torque specs when you're flying an airplane the horsepower means absolutely nothing if the engine can't put out the torque to keep the propeller turning. Why am I not hearing any of this in any of these videos that I'm watching. And it's not just this Channel on RU-vid nobody wants to talk about torque spec. The only people I hear talk about torque specification is when recently I was watching a video on the lancair lx7 with a turbine engine. And at Cruise it is putting out a constant 230 ft lb of torque. Precisely the number I need to know if I'm going to investigate power plants, and power needs for different aircraft and how much power the engine has to put out. Horsepower is not power horsepower is a measurement and a specific RPM of the possibility of the work the engine can do. But if you've already run out of torque on the engine and you're trying to do everything with just horsepower you're missing a third of your power band. You can have 130 horsepower engine that only puts out 90 ft pounds of torque. When you might need the 170 lb of torque to get the plane off the ground. Why doesn't anybody talk about this specification. Every time I look at a video on engine horsepower for automotive application I listen to torque specs across the RPM band and horsepower across the RPM band. But in aircraft and boats the more important information to know is the torque specification because you have a constant load on the engine.

Thanks for a great informative video about engines

I owned one of these 1000cc engines in an Apex sled it is the best engine I've ever seen,What about the Yamaha R1 racebike engine

I learned something. I thought Steve Henry was just a motor genius and modified his own engine.

EPex is cool, but the EP912STi at 155hp would be amazing

would this work in a Cessna 150?

You should ask only one question at a time. Multiple times 2 or even 3 questions were asked before he was given a chance to answer. This makes it hard to effectively answer the questions.

Suggest test as aviation engine， roll into spin to see will it keep going. Second test should be the sudden temperature drops. Love to own a such engine.

Thanks for a really informative video.

Excellent discussion!

What is a Norton cub? Do you have a website link?

There's a reason why those WW2 engines are still in service, they are simple, reliable and they work!

22:00 At last we can get an idea of engine capacity and not just HP. I must be old school!

Thanks for a great video.

AGORA A ROTAX VAI MELHORAR BASTANTE. VOU VOLTAR A USAR.

AWESOME AWESOME AWESOME

I didn't know that Norwegians have such a strong U.S. accent..

How much is this engine?

Let your guests talk before you but in with what you think is an intelligent question. Your questions only mean something to you, not us

It’s Fee-yords Bryan.😄

The Edge Performance website is not very informative. The Rotax derivatives are not even there. A concern is for instance the power requirements of the electronics - not specified. I'm sure I can think of more. None addressed on the website.

How much bro one unit

wave runner engines I think are 1800cc

liked

Giving the Rotax 670 sitting in my shed an inferiority complex.

Maybe think a lot shorter than 43 minutes for a video.

iDrool

Man if that ain’t price Gouging I don’t know what is. whoever heard of paying that much for a dog gone snowmobile I know they weren’t getting that before. WOW mention a plane they go insane

offer your parts for "marine use only" and negate all liability.

Do you really think EA people have a short attention span?
