hiya, where i am we have a sand quarry and the terrain is bit rough in places,i am trying to build my yacht so it can handle it better,theres loads of smooth parts and tracks etc too,and its always windy here as a bonus ;-)
wheels and tyres i have in mind are 100cc kids quad and sized 19x7-8 (aeon cobra 100cc), they are pretty light weight too,also could someone clarify why the front steering forks are (to me being a motorcyclist) at such a daft angle? is it to make the kart run straight without really steering? (ackerman effect steering but on a severe scale lol)
and my next daft question is........ we have our own quad/bike 3.4 mile track (very wide open space) with a few jumps,(hehe) think you know whats comming? lol, does anyone here do jumps with ur blokart or other terrain roughr than flat beach sand? (and grass). my m8s bet me i cant clear the double jump in the quarry! i bet him i could :-O

Do the jumps, I dare you, but make sure you video it for us all to see !!!

I have had my lefroy mini airborne,

landing was a very memorable experience.......
no damage to the landyacht at all, but I have am pretty sure my kidneys swapped sides

Gizz so how do you explain the king pin angle on a car ? A line through the headstock on a motorcycle intersects the ground infront of the contact patch of the tyre to provide castoring action to make it stable, the same with a car. However the land yacht's axis extension is behind the contact patch relying on the weight of the yacht to centre it.
Even on chopper motorcycles with extreme rake on the forks the turning axis is infront of the contact patch on the tyre.

The front geometry of a land yacht cannot be compared to any other road vehicle

Cheers tim

which is nothing like cars and bikes, thats that one sorted then

thankyou for a sensible and informative explanation Hiko, it wasn't me that said they were daft, I just said they were nothing like cars and bikes. now it all makes sense.

Of course it's doable, been done a zillion times since they were first pictured in the Pyramid hyroglyphs (seriously).
Just be ready for the landing. Friend of mine in the UK landed heavily on Mablethorpe and fractured vertibrae, and was not working some years later.It does depend on how you are sitting, yacht design, ferociousness of the landing etc etc. You have been warned!

I am pretty sure I mentioned that I had my lefroy mini airborne somewhere in this thread,

seriously- all joking aside- its not something I want to do again.

It hurt.......lots, and for a long time too [several months]

I was very lucky to get away under my own steam.

It was much like being dropped onto concrete- flat on my back.
The landyacht bounced much better than I could ever hope to.
