OK for all of you that go to a Nascar race hoping to see a crash, here are some pics of the cartwheeled gyro.

Well here you all go, here is the carnage to my new prop, less than 2 hours on prop, really cool Brent Brown tail, Sorry Brent! Plus the bent keel,mast bla, bla, bla, I'll build another one later, but right now I just want to fly, I've spent over a year rebuilding gyro's. :) :p

I hate those sort of pix, I'v got some somewhere of the ferel after I smashed it to bits only 8 seconds into my first solo. :rolleyes:
I was pretty pissed, :mad: but not as pissed as you would have been Scott,I didn't build mine.
At the rate I started,I couldn't afford the time to build mine.I woz good at smash'n um tho. :rolleyes:

It don't make me feel good looking at those pics either, but I am trying to learn something.

Sorry Chris,You took that the wrong way mate,I ment it brings back bad memories to me,but I also reckon they should be posted for everyones benifit.

There was no offense taken, Birdy. That was sort of responding to Scott's Nascar statement at the top.
I feel bad when anyone bends up their pride & joy. I hope I never have to post this stuff.
We came close when I had the nosewheel trouble. Scared the hell out of us twice. I want a nosewheel I won't have to even think twice about.

Here see if this makes sense.

I spent my money on Bikes, Broads, and Booze, The rest I wasted.
Makes sense to me. :D :D

Thanks Scott. So the part that came apart was only pressed in & spot welded to the fork? How much of that fork did you make? Basically, the bottom fell off, right?
It looks from the pics that the stationary part of the system stayed put just fine(the neck).
If you had the opportunity to do it again , what would you change?
Are you gonna try to rebuild at all?
The nosewheel on the Soma is quite different from others, yet it is similar to the Sportcopters. Go to SC's website & read about their amazing nosewheel. Then look at the price! It is a piece of artwork though. I just think I prefer a steerable nosewheel.
They both have some serious caster angles with a swingarm/ shock system. How does yours seem to work so far? Does it have the "buffer" system for shimmy? How about some closeup photos?
I keep thing of a shopping cart wheel.... self alligning.....but when they shimmy,I want to grab another cart.
Noone is yet to give me any type of data for caster angles....Looks like I am on my own ,AGAIN !
You had a pretty good rearward angle on that wheel, how did you arrive at that? It looks like your axle might have been as much as 3" behind the pivot point. Imagine how much more bending forces that placed on the broken joint as compared to straight up & down. What made you use so much caster?
The old AC's & other machine use a forward rake. Even the CLT uprade uses what I would call a chopper style fork. Where do we draw the line? Front tilt ,like Brent's , or self castering like ours'....Anybody??????
Thanks again, Chris

Crhis, the caster angle, or trail, like on a motorcycle, the more trail you have the more stable it will be.
You need to have your pivot point in front of the axle. a stock bensen runs about 4 inches or so, same with motorcycles, it seems that around 3 to 5 inches is good.
Have you looked at the Sparrow hawk? Dominator? how about your old A/C unit?
It seems that a rear castering wheel is more prone to shimmy, butthe principle is the same, as long as the pivot point is ahead of the axle, it will track in a straight line.
And on my nose wheel, the part that broke was the ONLY part that I didn't make! that's what pisses me off. I should have just started from scratch and made the whole thing, that way I know it would have been overbuilt.
