Could you guys be of any help?

I need some sprung oleos, around 150mm from bottom of wing to axle centre to take at least a 90mm wheel. Probably offset or inverted U.

I've looked on HK and nothing will suffice. THe Robart ones are an arm and a leg though!!!

Most of the oleo legs you can adjust the length by how long the leg in the retract is, the piece you attach the oleo to.

This one says it's 108mm, so you need the retract leg to be long enough to get the 150mm.

Thanks, both..

Inwoods maybe the best bet, as HK offset oleos are only suitable for small wheels (76mm). If I put the exact scale wheels on, I am looking at almost 100mm diameter! Mind you the inwoods is title misleading; It states "Offset Oleo Legs..." but when you look at the listing it's actually one..

I did also toy with making my own as well.

Kingfisher Aviation are agents for Dave Brown retracts. He does large scale oleos too. They are good quality but not cheap.....not sure that such a thing exists There is a downloadable brochure on their site

These are what I used on my Mustang, 3 3/4" wheels, but sadly no longer stocked. You could try TND to see if he has any.

Try fighteraces.co.uk, if he hasn't any he may well put you onto someone who has.

We are getting back to the arm and a leg costs

The OP was to find a cost effective solution and eflights solution allows a number of alternatives

Haha indeed!

I think I may buy the 110mm oleos and then use this as a basis to construct my own. Pencil sharpened at the ready!

I think you would be better off getting some a little too long and cutting them down. Most are so cheap these days that it is not worth trying to make your own.

At the risk of upsetting someone who posted above, whatever you do, do not have an exposed length of piano wire between the oleo and retract unit. It will bend on the first flight because it will generally be much thinner than a wire leg by itself. The oleo must be hard up against the unit. Even so, they bend very easily unless you can obtain some really hard steel rod.

I agree Martin. Here's a little more detail. The Piano wire exitting the wing will be 5 or 6mm and yes it will not be that long for the reaons you state.

The reason for the post was that I really wanted to incorporate a 90-100mm wheel in there, and being a Stuka, it would have to be an inverted U shape leg, which puts the leg on the C/L of the wheel,so the wheel spat can wrap around it.

Those oleos for theTexan look great, but in practice would never be seen of course.

Here's what Lindsay Todd did with his: -

You can see the inverted U that wraps round the wheel

My thoughts are to get an existing oleo, and dismantle it and make the bottom part as I have a lathe etc.

Mind you, it may be best to forget the 5mm piano wire and go for brackets.. !!!!

Stuka ?

here's a picture if it helps for the Black Horse model ---

Doesn't the Stuka have big wheel spats that cover everything up.

Yes that's it Ray!

I've measured to the drawing and 100mm oleos will do from HK; I dismantle and then make my own bottom section with inverted U bracket for the wheels. I'll also use the BH mounting method, which means I'll redesign the Beech bearers in the wings too.
