Fantastic project. I ride a Yamaha Fazer FZ1 road bike. Awesome engine. Love the Kolb Ultralights.

[@KGFlyer55]

You're working through the exact project with the Firestar that I am.looking at doing. Great videos 👍

[@bkairys]

Nice! Would love to see it. Anything your doing that is substantially different than mine?

[@blacksheep933]

i'm building a quad city challenger 2 with a 503 dcdi so you really got me thinking I would love that extra HP!!

[@bkairys]

Only 33 lbs more than 503 with e start

[@davidallen9526]

I'm running a 503 duel carb w/ starter on a Flightstar 2SL and this has got me thinking too!

[@whisperingeagle]

It would b great on my quad city chlg 2. I would love to have the xstra power and 4 stroke reliability.

[@jasongrinnell1986]

I’m thinking this engine is not good for a Part 103 UL?

[@racingwithbigt]

It sounds so good!!!

[@DeadRoman]

I am very interested to see your results. I may end up using a Phazer on a Chinook build.

[@bkairys]

Love Chinooks, would probably have one if I could find one not in Canada

[@Rico11b]

It needs a cowling build around the motor to help reduce drag.

[@blacksheep933]

sweet !!

[@gulloorandhawa2287]

super job

[@patrickmckowen2999]

Looks good 👍

Johnny Knoxville modifies a phaser!

[@tonta332]

Hi bro ! i really like your video , i subscribe to your channel , i have started studying airplane making since today .thanks

[@alanswanson1952]

Is the bolt pattern for the gearbox the same with the phaser and apex? The reason I ask is because I want to put an apex on a searey which is also a pusher and would like the gear box to hang down like yours. Do you have cad files of the pattern?

[@bkairys]

Its not the same between the 2. I hand made this adapter from scratch. Its fairly straight forward. I think you could do it on a Apex as well.

[@Brutalwhan]

Don't you need to torque the prop bolts and wirelock them?

[@DustinApple]

id expect you to be able to turn a lot bigger prop than that little IVO.

[@bkairys]

No clearance for anything much larger unfortunately..I'm happy with the 1,800ft / min climb performance.

[@DustinApple]

@@bkairys could got to a 4 or 5 blade Powerfin without increasing diameter i guess.

[@MrHanowski]

Nice progress! Apparently you don't need an E-box to have electric start. Suggest evenly and progressively torqueing that IVO to 200in-lbs. Can't you adjust idle to eliminate need for clutch? I don't want clutch either.

[@bkairys]

I tried! Clutch was only way to get it to work. Think ignition timing has something to do with it.

[@tomvancil8213]

Could you comment on the weight, power $ fuel burn difference between your 503/582? And this new set up?

[@bkairys]

I was getting about 2gph is the kolb and about 3 gph in the phazer kitfox. 503 gets around 4gph, 582 4 to 5 gph.

[@rv7builder397]

Really appreciate you documenting this; I've got an old Twinstar that I'm paranoid about flying with a 2stroke. But tightening the prop bolts with an impact driver? Really? I hope that segment was just excessive editing. :-)

[@brysenelliott2527]

I know I am kind of off topic but do anybody know of a good website to watch newly released movies online ?

[@brysenelliott2527]

@Rocco Michael Thanks, I went there and it seems like a nice service :) Appreciate it !!

[@roccomichael8577]

@Brysen Elliott You are welcome :D

[@leestuart6749]

Cool plane, how much was the Yamaha as you have it?

[@bkairys]

Bought an entire snowmobile. Yamaha phazers are out there for 2500 to 5kish

[@edwardhasiak7961]

Looking good! Where about are you in Michigan?

[@bkairys]

Near 69g

[@motorcyc1]

What is the gearbox you are using to bolt on the Yamaha engine? Thank you

[@bkairys]

Watch part 1 for more details.. rotax c box

[@motorcyc1]

@@bkairys Thanks, I'm going to try this setup in a month. You said, I believe, you had to cut the engine shaft diameter but the number was more or less. Can you elaborate? Thank you. Also would you fabricate an adapter plate at a cost? Thanks Eddy.

[@motorcyc1]

Disregard, I was buying a kolb firefly with a 503 rotax engine but the wings and fuselage had quite a bit of damage. It had been sitting for over two years. So I'm going to wait till April and go to the Sun and Fun here in Florida, check out the vendors. I would like an amphibian ultralight aircraft more so because here in Florida there's a lake or river around every city. Thank you for your help. Will update you soon.

[@bkairys]

@@motorcyc1 do you mind sending contact information to [e-mail]. Im always looking for another project like that.

How can you be contacted if I need your assistance installing the software and engine? Thank you.

[@Paganiproductions84]

Would a yamaha r1 engine fit in a ultralight plane

[@bkairys]

Yamaha apex is a R1 engine better suited for aircraft. Lots of those in planes now.

[@Paganiproductions84]

@@bkairys Yes i know about that

[@Paganiproductions84]

i don´t seen them here in europe mostly rotax engines

[@patrickwehling167]

What size. T thickness tubing motor mount..?

[@bkairys]

Its Recycled tubing from a Piper Apache Engine mount. Not sure on exact dimensions.

Thanks. You are an innovator aviator!

Why???

More power = more fun and more Stol

[@curvs4me]

What pitch did you go with for the prop? Has to be significant with that much more power.

[@bkairys]

its an adjustable pitch prop. Not sure on the exact pitch
