Love your inventive touches. You do such a great job describing how you worked on it and explain lots of details.
Very impressive Ben!
Love, Mom
I was a Yamaha dealer for 26 years and will say the Apex power plant is a beast. When we added a turbo it was crazy.
that's what i want - on a Bearcat4 on floats. (up north in BC Canada)
Great work Ben!! I am so glad to see talented people like yourself getting involved with the Yamaha
Likewise! Your Gearbox Is a thing of beauty and I'm proud to have it on my Airplane
as a bush pilot I took off over gross when required (more than a few times) - because I burned off fuel so when I landed i was within the envelope. I was aware of what I could and could not do re flying - the kicker was we had a 5000' runway at home base for an easy take off. Not everyone has that...
An Apex on a 4 ought to be a rocketship at close to those weights. Can't wait to see it finished!
Those engines sound so sweet !
12:46 sounds about like the snowmobiles. Still can't believe these engines are going in planes. Guess that is a testament to the reliability
Good morning 🙏 Ben, I'm perry from Washington state USA thanks for your share and I subscribed your channel already, i like airplanes and flying high and have a wonderful new year 2023.🥰👍👍🙏🙏
Hope all is well with you and the family. Look forward to an update on the build, the flying, and the business - would really like to hear how it's going for you. All the best!
Great work! Thanks for sharing! Those long battery cables are going to weigh a few pounds…
Looking good
More great work from a real craftsman
Ben,You have done a very good Job,...! Thanks for these Ideas,...! Greetings from Bavaria...Curt
I think you're doin' a fab job Ben.
This build is absolutely beautiful. Love the yamaha coversion!
Really stepped it up this time! Nice work
Can't wait to see it flying
Awesome!!!
Looking awesome, love the cad printed parts.
Amazing build, can't wait to see this thing in action.
That thing is badass. Hope it works out for you. I’m building a sidewinder set up for my kit if it ever arrives. Gear box is on . Turbo set up plumbed and it’s on the mount. Just need an airframe to hang it on.
Awesome! Looks really good. Keep going! Can not wait to see it fly!
Way to go! The work you and Scott are doing is really amazing
Great work! Going to be awesome!
Lookin cool man!
Heck yeah!!! Awesome work!!!!
Hells ya! Nice job.

Yeh- wow... I'm amazed with your technology such as 3D printing parts.
Over and above the CG assessment and weight distribution. Making "in roads" that's for sure!
The air cooled Yamaha, very compact firewall forward. Not much room for a wrench and hands. I wonder what is the benefit in short engine mounts. I want to "get in and takeoff the mags and drop the oil etc
🌏🛩️
I enjoy your videos!
I think you are talented with maching and 3D cad printing.
It is my opinion that you may want to consider your battery placement. Consider your voltage losses, and possibility of RF interference on such a long runs. Placing a larger battery with more cold cranking amps behind the traditional baggage area may have the same effect on CG as the more distant location. I know this will be more total weight. You still may need to run >6 ga wires. I would bond the plane near the battery, but still run a negative battery return wire to a common distribution point on the fire wall.
Starting engines in winter uses a lot of power.
(Warning this advice may be worth less than you paid for it. I know some about electronics and RF interference, but nothing about aviation)
Thx! I do plan on running a lightweight lithium battery up front for redundancy.
looks awesome! nice work. Defiantly take alook at E - Props for your prop. you'll save a few pounds going that route though. I haven't tried them yet so I can't speak for the performance.
Thanks Jonas, Ill check into those props. I've been watching your channel for a long time. One day I'll get this done and fly it out there where the big boys play!
@@bkairys sounds like a plan!
👍
Nice.
Dangggg....I might need your help starting mine soon.
Consider a servo bypass ahead of your muffler to a short straight pipe, when you want/need a few extra ponies. I might do that when I build mine just for T/O. Looking good though. How much for the 2 used titanium header sets?
Nice video. Wonder if you wouldn't be better off with a lithium battery at the firewall, and add lead at the tail for CG adjustment. Long battery cable runs loose power unless they are big is one reason I'm thinking and some of their weight is ahead of the CG. Also, the further back the lead weight is, the less of it you need. The last 3 Kitfoxes I've done, I widened the fuselages at the doors, not much extra weight, and way more room when you have the other guy with you. My Kitfox 4 with 912 and grove gear came in at 645, so if you can stay below 650, that will be real good. Just a few thoughts, like the videos. Jim
Hey Jim, I do plan on running a lightweight lithium up front and the lead in the tail for redundancy as these engines are boat anchors with a working battery. Yes I do hope this ends up under 700 with 150 hp!
then at 13:32 you superimpose your design over the engine. love this ..briefly how did you do this and what software products do you prefer.
Way to go! What's the app you're using to overlay the CAD assemblies on the photos of the aircraft?
Just inserting "canvas" on work plane as a guide in fusion 360
Hallo, i am based in South Africa. Where did u buy the gearbox and what is the price? Saw your video and what horsepower does this engine deliver?
Could you tell me the physical size of your radiator and how many coes it has? I am putting a 3 cyl. 973 onto and x-air, (yeah, most people don't know what and x-air is) and I am trying to get an idea of coolining needs. Nice work on all of it. I like the 3d printed stuff.
Sounds like a cool swap! I don't know the size off the top of my head but It's a 2008 Kawasaki Z1000 Radiator. Another 1000cc motorcycle engine so in theory this should work fine.
@@bkairys Thank you, this helps a lot.

Hi... i came upon your content and I have so many questions. im close to buying a kitfox kit. you are doing one thing that i have to master. you are using a graphics package to image items, three d print them, and then actually built the part for the plane. i subscribed to your content. more questions later. thanks
hi..all i need is a basic point in the right direction. at 2:31 you superimpose the engine mount and then transfer the image to a rendering/design software package. could u please briefly tell me what you used and the name of the graphics modeler to create the design. thank you.
Cad program used is Fusion 360. I imported a "canvas" on my sketch and scaled it with corresponding points. Worked great!
I wanna put EFI on the rotax503, has anyone tried it? The bike 250 throttle bodies are pull push twist grips. microsquirt looks like it'll work it.
How will you unclip the battery when there is fabric on the sides? Maybe there is more clearance then it looks on the video.
Why are these ideal again? A quick google didn’t remind me. ThAaaaaanks
150hp in a package they weighs as much as a 912 or O-200
What thickness titanium did you go with for your firewall?
Also have you considered selling your 3d printed parts files on your website? If you don’t already, I’m sure you’d get a decent amount of interest from people purchasing your file downloads….me being one lol.
.020 titanium on the firewall. I do have a select few parts on my website. Message me on there if your interested in a specific thing, I'd be glad to help.
@@bkairys for sure man, you should almost create a library of file downloads for purchase. Not sure how you would stop purchasers from sharing it to others but I’m sure there’s a way.
@@bkairys I tried emailing you through your website about a week ago, but my message might have gone to your spam folder.
Did you built in some offset to counter the engines torque?
Where you located. I’m in Boise
How much more does the apex weigh than the phaser engine?
Do you have a carbon fibre intake for sale now for an Apex?
@patway4683 Not yet but will eventually when I make my own and have the molds made.
@@bkairys ok right on
hello Ben ! I want to buy your engine, do you sell it? I live in Vietnam
What are you doing for a heat exchanger for cabin heat ?
Hi Ben, wandering what you've done and even more I would like to know how did you manage to use the engine speedometer for your airspeed?
