Sadly this appears to no longer be available. I needed one of these for a 582 delete.....

Beautiful workmanship!

Looks beautiful Teal. Is SkytTrax spelled with 1 "t" or 2?

What made you go with spur gears rather than a planetary arrangement?

Price??

Would like to hear your feedback regarding how you design and validate a psru, and in particular, how you get thru or around the resonant frequency phenomena.

Looks nice! You said Phazer is 75hp. I thought it was 80hp? Does the gearbox require the clutch? I prefer no clutch in a Powered Parachute application because when you kill the engine after landing, you want the prop to stop turning immediately to prevent damaging the parachute which is falling behind you. Are new Phazer engines available, where, how much $? If not, source for used? Thanks!

Well done as always sir.

Looks good. It would be easier if you had direct links in the description to this gear box for pricing and specs etc.

Great tiny machine ...

What a work of art! Both in design and execution.

Very nice sir.

Hi. Can i use this adapter on the Yamaha sidewinder engine ? 3syl turbo from sleds.

So how do we order from you?

Hi Teal, I've seen some internet rumors that you're now making a 3-gear reduction, to make the prop turn the right way. But 'the google' is failing me trying to find any info on it. I've even tried that Devil's spawn, facebook, but still no luck. If the rumor's true, do you have a website with specs, pricing, etc? Thanks, Charlie

Questions. Whats the weight of this rx1 & rotex c setup? It seems undoable for a conventional tractor design unless you wanted the head above the cowl ?

Is the exhaust manifold stock? and how much does the entire engine weigh?

How do we contact you?

The gearbox is it an a b or a c? That your are installing it would have been nice to known at the first of the video

Teal, I wish I had 1/2 of your abilities & knowledge. Thank you for sharing with us. Question...I see the 3 cylinder in the FX Nytro sleds have a slightly lower rpm range which might be beneficial, but can't find too much information on this engine. Looking up part numbers, the inner crankcase cover has very similar, but not exactly the same number as the RX1 engine. Would your adapter also work on the 3 cylinder FX Nytro engine? Thx.

Do you know if you could do acrobatics with this engine? From what I understand automotive engines fall apart upside down and with too many negative Gs. Thanks!

will the adapter work on a YZF-R1 engine?..

What’s the Rotax box rated for HP wise? Nice work. Love the innovation.

Great video. What do you think a realistic conversion would cost after purchasing all the main components? A new 100hp rotax is around 20,000

How about a Billet Single Case with Rotax Provision 8 Data based off a Skidoo/Rotax Single for the Ultralight crowd. Ideally, a Skidoo/Rotax 340 TNT Single Type Case with a Skidoo 550F(76mm) Reed Fed Cylinder. With a 277UL 66mm Crank (76mm x 66mm) 299.5cc, with a 68mm Stroke, (76mm x 68mm) 308.6cc, with a 70mm Crank, (76mm x 70mm) 317.6cc. 550F Cylinders have been Big Bored to 81mm, (81mm x 70mm) 360.8cc. 299cc if 90% efficient at 6500rpms = 41hp 308cc if 90% efficient at 6500rpms = 42hp 317cc if 90% efficient at 6500rpms = 44hp 360cc if 90% efficient at 6500rpms = 50hp

What reduction gear with this engine

I saw a post of you that you made 1 hour ago and there is a case cover with reduction gears for the Yamaha Apex engine could you pm me details about this. I have no way of contacting you I can't call you I'm in Canada

I been trying to send you a private message and I just can't find how. I was told that you are working on a new adapter with re-drive for the Yamaha engines could you give us some details the engine types? and what ratio you will have available. I found online a post you made 1 hour ago that you are making a cover with reduction gear for the apex engine could you tell us the model and engine CC? could you PM me your email?

I do not have a website Interested parties can contact me directly at 623 734-0185. Teal.

how do I get a hold of you a out the adapter. i can't find a website

It seems you oversimplify this installation by a whole lot.

I just read that Rotax is discontinuing the c box and going to the e box. Will this fit the e box?

no. i am only building a adapter for the rx-1 engine at this time

hello, can you make a backing plate for any 4 stroke snowmobile engine? 140 is way more hp than i need and i have another smaller engine in mind. email?

Will this adapter work with the Yamaha Phazer 500 cc 4 stroke motor? They appear to use very similar internal gear reduction drives.

What determines how much you need to machine off the C gear box. Thanks, Jim

Hello Teal Jenkins. I am a pilot from Norway, and I installed the 3 sylinder Yamaha in a CH601XL in 2006, it was not aproved. Today I have this engine in my Super Petrel with 100hr on. I have the gear with clutch from airtrikes.net in Canada, but I am thinking of using the Apex engine and I have a Rotax C gear I can use. I might need your adpter, if possible. Please email me at: kurthansen1 (at) gmail.com.

How does one get ahold of you to buy this? Thanks

One thing to Note: The steel band will need to be removed from the rubber disc once it is mounted to the Flywheel.
