I had this engine in a 2008 yamaha apex ,it was a fantastic sled ,how does the weight of the engine/gearbox compare to a rotax 912 or even a rotax 582 two stroke
I love my 2006 Fuel Injected Yamaha Snowmobile .. but I thought Rotax part of Bombadier builds a purpose build small airplane engine.. I guess it costs too much ????
Why not just use the motorcycle version with a built in, highly reliable, gearbox? Then all you'd need is a solid mount for the prop, and could use a chain drive just like the bike would? It's a tried and true system we know to be extremely reliable and easy and cheap to maintain...
@@ultralightnews But you should also mention that it is just a phone number. No website (yet). European - they might have difficulties with a phone conversation.
How does it hold up to thrust loads and gyroscopic forces? I often think that most gear boxes never consider the gyroscopic forces as the plane yaws or changes pitch.
@@PDZ1122 I dont believe that statement for a minute. There are unique forces at work on the housing. This PSRU is developed in modern CadCam, which almost all packages come with structural analysis. Pretty much fool proof nowadays. It is machined from billet, stronger than cast. What I have said above was in no way ment to diminish this persons capability to design this drive. It looks like he is doing well for this newer market
Teal, your my latest hero! Well done!
Picked up an '06 Apex GT with less than 2K miles about a month ago for a donor....Keeping room on my credit card Teal.:)
Totally awesome!!! Keep up the good work!

GREAT INFO/INTERVIEW
He needs help getting a website marketing and some inventory. This is the way to the future. Oil pump and an oil cooler.
I know I wish he sells the engine ready to go.
I agree he should have an external oil cooler. Especially if you want to install a turbocharger.
Itis a Dry sump engine so oil cooler would be easy ..
Could one of these fit into a superstol cowling?
Is the engine computer up for handling thin air?
Also you need a website for this bad boy. Pretty easy to set up these days from what I understand.
It's a fuel injected snowmobile engine . Duh !
Dan, Edge Performance-Norway is developing a turbo for the Y-Apex engine....200-300 hp...new internals for the 300hp version...not for the lower hp's.

How do you handle torsional vibrations ?
The Yamaha Snowmobile engine mounts a CVT clutch directly to the crank shaft.. no Harmonic balancer come to think about it ..
Here it is, July 2020, and it's for sale where?????
In Arizona - just call the number on the screen.
We need economical engine option badly. Since Rotax , UL etc have not done the industry much favors by lowering cost.
You should publish contact info in the comments
Skytrax googles for some European company
The contact information is ON the video.

I'm pretty sure that anyone who can design and build this kind of gearbox is capable of thinking of such obvious considerations.
And harmonic isolation? He seems confident that the Spragg clutch will deal with harmonics. Centrifugal clutches have been used in the past.

Operating rpm way too high for me. Hard pass.
