Good explanation of your gearbox. I understand the bearings and why minimal oil when properly directed through the gears is more efficient and produces less heat. I have watched your motor and gearbox combinations as they developed over the years and I really like what you have now. Good video and I really like that I have had a chance to see the inner working of your gearbox.
The tool box/workbench/podium Jan is speaking behind is the Home Depot toolbox that My wife Penny uses as her mobile island/storage drawer cabinet in our kitchen. It’s like he’s working in our house.
The rubber "cushioning" component on the flywheel, known as a "giubo" in German car driveline technology is designed to take significant torque in either direction. On my BMW 3 series from 2003 (in my case supercharged up to 295 ft/lbs and 340hp), it tends to last 80-100k miles under relatively normal operations in a stick shift or automatic car. Mine is only starting to begin to crack at 100k miles. Some BMW owners that drive their cars hard - track days - may get a slightly shorter life out of them, but it's still a robust, long-lived piece. And you'd see cracking on the annual inspection to know that it needs to soon be replaced. I've seen pictures where they were totally trashed and spewing nylon fibers but they still worked ok. I'd replace at first signs of cracking rubber on an aircraft engine application, as I'm sure most would, but they do tend to hold up a good bit beyond the initial cracking.
The only reason I can understand why an airplane should be hand propped is because it doesn't have an electrical system and a starter like a J-3 Cub. Why would anyone want to fly an airplane with a dead battery I would rather figure out why it's dead if it's just been because of sitting around then put a battery charger on it.

Thank you. We are also very confident in the 3 gear drives we now have for the 3 engine sizes.

I will certainly be using a Viking setup in my 701 when the time comes! You are doing great things!

this is really cool. I like where they are going with these motors.
Viking engine is a nice future safety

What air frame have you installed that 180 Turbo in?
The guy dancer in your right is a distraction to what you're discussing.
What cod material is made the gearbox ?
Here is something on the gearbox th-cam.com/video/SODvLtvmYbI/w-d-xo.html
I WILL ADD SOME LUCAS ON THAT GEAR BOX...😎
King of engineers.
Check into this guy's reputation and history, before making statements about him (good or bad)
