So in studying 2 stroke engine design I found out that most paramotors are not direct-drive but rely on a reduction pulley and centrifugal clutch. But in studying pictures, I discovered the stem that the entire propeller/secondary assembly rides on... Is just a mere tab molded into the crankcase. I couldn;t believe my eyes when I saw that... Hundreds of pounds of thrust, prop strikes, axial load, radial load, it's literally moving the entire setup... And it's just a small metal tab. Am I missing something? I circled the tab in black in the picture. SO this tab supports the weight and thrust of the prop entirely? If it were me there would be a through-shaft supported on the other side as a minimum, and even that would be frighteningly under engineered to me... But one tab?! I mean, obviously props aren't falling out of the sky, but... Just the one tab? I really need to understand this... Thank you!

So I'm new to paramotoring and I am trying to set my sights on what I want to do. If this is a no-go then it would be cool to know that, and also, why it's a no-go. I am a 200LB 6'1" guy (I'm fairly fit). I have two dogs, whom I cherish, one weighs about 50 lbs, the other, about 40 or so. Went to college to learn to weld and I am an experienced fabricator. Experienced mechanic, electrician, etc. What I *want* to do is to be able to go remote camping with my two dogs, via paramotor. I live in the desert, and the possibilities are endless. A trike seems almost too good to be true, if I could do it. So, me, 200 lbs, pups, 100, and gear, 100? Is that doable? Dogs will have earpro and eyerpo and will be harnessed in. The last consideration would be, I might not have a lot of "runway". Do trikes need a long runway. This is why I stopped considering gyrocopters, they need too much runway. Of course I reckon scouting the runway is a prerquisite for landing, don't land where I can't take off from. Cacti. "Oh crud, I did't see that cluster of Chollas!" if I get a wing full of cacti, will that destroy the wing? How durable are wings, there can be many things to snag when landing and it hits the ground.

OK, thank you guys.

I have experience with formula one motors, and have owned the Cannondale E440 as well as the Honda RF450X, both of which mirror the F1 style 5 digit rev ceiling engines. Studying welding on college, I know a great deal about fabrication, what is the limiting factor on using a Honda CRF450X engine to drive the prop of a paramotor? Cooling and radiator aside, cetrifugnal clutch etc. These are stone dead reliable high revving engines. I even see a certain company using the CRF250 engine as 4 stroke fodder to power a parachute. Any reasons why not?
