Main Struts

[Sonnyj]

Hey Guyz
I was just lookin at Dings gyro in the for sale section, and noticed that the main struts are just what I've been trying to add to my little gyro.
Could anybody show some more detailed pix? How dose the axle fit up and how dose it connect to the fram? What size tubing should I use? You know, all the important stuff.
Thanx
Sonny

Sony, I've just sold that gyro so I can't take any photo's for you. It is a standard Rosco machine. The suspension was pretty light and I think a few of that design being aluminium tube may have folded with a bit of rough work - but don't quote me only what I've heard. Maybe same design made up out of molly might be better.

Some one may be able to take a few photo's and put em up here for you Sony.

[Butch S.]

take a look at the pivoted dominator set up I like the look of it as even if shock fails suspension dosn't
as some guys put shocks straight inline in top strut as in rotor's old vw gyro this is in my opinion a no no no .

Butch..............interested to hear why you think shock absorbers on the main strut are a no no.........

By the way..........succesfully used this sytem for YEARS.........[and they got a hell of a workout]
Just like me dirt bikes over the years, impossible to imagine riding me dirt bike without shockies

[rotor]

Sony, don't get confused with what's happening here. My old VW gyro used shockies off a Kawasaki 1100 road bike and chrome molly frame which did take a bit of rough out of rough strips ... but they add to the weight ....

The gyro in the picture you mentioned is a Rosco machine with standard Rosco suspension - not to be confused with what butch is talking about.

The Ultra White is the lightest machine Earnie makes.
At 300 LB It's too heavy for a leagle Ultra light here.
254 lb is the limit here, and I intend to meet that requirement.
At this point my little gyro weighs 238 lb and I still need to make a pod and install the inst. and a newly aquired GPS.
I figger I can dump 4 or 5 lbs by changing the mains.
Thanx

What did you think of the Rosco setup? :question2:
I will be flying out of a cow pasture ( paddock ) so I will need good equipment. :arrow2:
I can keep the strip smoothed out some what with my old motor grader. :yes:
Thanx :cheers:

[rotor]

Yeah, Biggenden isn't as smooth as some. From what I've heard, they have been known to fold on heavy landings.

[Birdy2]

Standard rosco gear is pretty solid, and very rough.
Only time i saw one fold was when the machine spun in with a broken rudder cable, slightly bent one strut but didn't fall over.
Me ferel is much the same as roscos but with coil springs where he's got the rubber dampeners. Much better take'n off from rough roads and am still to bend it.[ tho i'v been try'n hard over the years.]

[rotor]

Straight from the birdies mouth ... thanks Dave


Got any close ups that might help Sony??

[Sonnyj]

G'Day Dave
Yes please, if you get the chance to take a few pix and jot down the tubeing size, it would be greatly appreciated.
Thanx

[Birdy2]

Sorry Son, a pix outa the question at the moment, coz i'm too f$ckn dumb to work out how to use it.
[Went over to one o the me neibours in the waza RAF for the new years pissup, and took this u bute f^&^&% camera that never took a single f%^$n pic. It was this close to get'n chewed when i found out it's f%$#n eye was closed.]
Its a basic wishbone setup with a 1" alu strut with a coil spring and rubber dampener inside the coils. Gives bout 4" travel.
[ I was a bit nervy bout the flimsy lookn strut so i sleeved it with good ol heavy gauge gal pipe. Don't think its needed, but its stayn, just in case. You never know, i could stuff up a landing one day.]

Russ read my original post
shocks inline in top struts that don't use the original pivots are subjeted to side load that try to bend the shaft this can NOT happen on a motorbike as at the top & bottom of the shock is a pivot point
this is the same as what dominator have done THIS i like
if you don't beleive me that shocks improperly fited can break ask loyd parsons

Hello Butch,

Sorry but I'm new here so if I'm asking silly questions please say so. Are the shocks pivoted at the upper most point only?

butch..............sorry but disagree with your post. Except the last line................yes if fitted incorrectly anything will break.

I for years had a shocky on each main strut, it was anchored at the bottom near the axle area, pivoting around a rubber bush. The top shaft of the shocky was a threaded shaft, this was screwed into the main strut, this strut then continued up to the frame or engine bed somwhere, where it too pivoted around a rubber bush mount type thing. Then of corse there was another strut going from the axle area towards the front of the machine,and the third strut going from the axle across to the keel, thereby creating the triangle effect, these were pivoted by means of eye turnbuckle thingos at the front attachment only. Now this system flew for bloody years all over Cape york, it got pounded, NEVER broke........ever. Mate it works well.....................FITTED PROPERLY

Hey B1rdy
Sounds like you need a cheeper camara.
When I was lookin at them, I found one that had the word AUTO on the dial, Ha, I says, thats the one for me. I have never moved it of that position and so never had a prob. Just turn it on, the thing comes alive and even pushes the leanse cover off for you, push the button and there you go. :focus:
Thanx for the info on makeing the landing gear, I have started to put it on paper. Can you suggest how to mount the axle? :confused:
Cheers :cheers:

Hey Sonny let me know when thaat package turns up your end just so i know,
:cheers: :focus:

[Sonnyj]

Hey Bones
Oh yea for sure mate.
You'll proly here me hollerin all the way over there.YAHOO, YIPEEE. :friday: :pistoles:
:cheers:Cheers

Hello Bones,

I was wondering what sort of gyro is that one that is beneath your name?

Ian

[Birdy2]

Thats wot youd call a bare bones machine. :hahano:

Yeh sonny, your probably right, like a disposable.

The one your talkn bout sound just like this one,[ the missus found it] "just push this button" she says, "then point it and push this one". na, f%$# thing didn't like the way i was pushn its buttons.

The axle and main horisontal strut is one pice chrom mo with the drag link welded to it just in from the wheel hub.

[Sonnyj]

Thanx Birdy
That takes the mistry out of the gear for me.
Now all I got to do is get started.
Cheers

Wish you had photos Russ as I haven't seen any that I liked yours obviously stood the test of time & I think all gyros should have suspension not important for landing but very much for take off
Butch

[Birdy2]

Butch, the sus i'v got on the wasa RAF has a scooter coil spring n shock mounted on a free to swivle rubber bush up top,[ origional scooter one] with bout 14" of strut screwed into the thread where there used to be a fork for the scoota [ kids mini bike momo shock]. The other end of the strut is 'rod ended' to the cross strut with plenty of free movement.
Is that go'n to put too much side load on the shock rod when take'n off corrogated roads???[ its almost virtical, can't see where there could be any inappropriate stress.]

[Butch S.]

Gday Birdy
Souds allright some blokes fit shocks with either no pivot at top or bottom or niether
these will fail as
1. the gyro is heavier than the bike they came off [with 1-1 travel ] thus more travel
2. if there is no pivot at the wheel the ark of travel will be transfered to side load
Birdy youve used a mono shock by this do you mean 1 shock mounted on one side as in PW50 or 1 shock mounted center of bike ?
Butch S.

[Birdy2]

Yeh, its easy to see it failn if its setup like that.
The shock i used is a replacement one[ as in a single mono shock in the regular dirt bikes] for one of them cheapy kids scooters made in China.
Obviosly the scooter is much lighter than the WASA, but how its fitted in the bike, its at bout a 3 to 1 leaverage ratio, so the streight weight capability of it should be 3 times the max weight of the bike with a blok sitn onit.
As it turns out, i'v had to turn the sping out to its softest compression and softened the shock to the max.
Works perfect.
I'm not worried bout the shock be'n able to take it, more bout the gear i'v used to fit it.
The rod end on the bottum is one of the origional rod ends off the old RAF setup.
They should be able to take the weight in compression easy enough ay???[ given theres no side load.]
