I'm always thinking of something new and different to piss off our educated engineers that don't come up with anything but criticism.
Still have to go back and have some more surgery in the next few days.
God figures Hell ain't gonna be enough !! Thanks Buddy
Well for an ‘ornery' old weed smoking sand bunny you come up with lots. Keep them coming.
Sorry to hear about the ongoing surgery, good luck with that and hope all goes well for you. Been there, and me too, will have more. Keeps life interesting though doesn’t it.

Default 670 Exhaust System

Hi Jake,

Your 670 project looks amazing, nice work. Can you share with us more info on your exhaust system? Did you design and build it? Any engine test info with this exhaust system? Can you share with us how you adapted the E-Box and if you had any challenges doing so?

Looking forward to seeing more of your pics and build progress.


Thanks for sharing your project with us.

The exhaust is from a Rotax 618.
I did cut, rotate and weld the muffler to meet my needs.
The block was machined by Rotax Rick to accept provision 8.
I am using a C-Box 2.62:1 with an RK-400 clutch.

This particular engine has gone through some serious modifications.
Compression has been lowered by using a .048 gasket under the cylinders instead of the stock .015.
I have cageless bearings on the wrist pin and crank pins.
Ceramic coated pistons.
Springs in the RAV valves were made lighter to compensate for lower RPM.
I will only be turning this engine 6500 instead of the max 7700 RPM.
Should deliver 85Hp.
It went from a duel Ducati ignition to a single Nippondenso ignition with computerized timing.
I am using Rotax 912 isolation mounts instead of the small Barry mounts.

Thanks for looking.

Still Dolling up my Bensen.
Finished the brake cylinders, main gear, front end and shimmy thingamajig.
Just have to paint the front wheel assembly
Ya see, you really don't have to be an engineer with understanding to build a gyro plane, just drill some pretty holes, paint stuff up and it will fly.
It has worked for several of the ones I've built.
I guess the trick is you just have to make it look like it will work and it doesn't even have to be shinny.

I use 8" Azusa aluminum on the main and Azusa light 4" on the front.
The tires are 4 ply Ton-Keep, some ching chong brand, but the most symmetrical tires I have ever used.

Thanks Guys.
Just havin fun thinking outside the box.
When your like me just Dolling up a Bensen and not understanding how they work, ya gotta draw attention to aesthetics instead of detail to engineering.
I found out that engineering and physics have nothing to do with gyroplanes,they fly because of MAGIC !!!
But don't tell anyone because our forum armchair engineers will wanna bring up Science, they don't understand Magic
