Urgently require a landing gear that can withstand upto 10 kg. It can be retractable but not necessarily.

Wow!
Never realised that the U/C legs alone could be so heavy (600gms) or so expensive ($ 108).
You could surely make it yourself at far less cost. Though it'll need 2-3 attempts toget the right strength+rigidity/flexibility.
A small one (for a 500gm model) I made 4 years ago was extremely strong (impossible to break), but was too flexible at the corners where it emerges from the fuselage. Guess the upper corners have to be thicker.
An alternative could be to find some 1/4" spring steel wire, and get it bent at a machine shop.
Perhaps flyingboxcar (veteran member here) could suggest something. His BIG Tiger Moth may be of similar weight  ;D.

If you are upto it, you could try getting some 1/4" steel rod, anealing it and retempering after bending.
I've done that successfully steel coat hanger wire, though obviously on a much smaller scale.

Or you could build one with several pieces of 1/8" wire (like a Tiger Moth)

Apologies for offering only suggestions instead of a solution.

Like Imperial Fire, we too woould like to see some pics.
Best wishes for your project.

Can you give the link of nose landing gear with steering. Or any idea of how to make it.

sanjayrai55

A 10 Kg model would typically have a 150 cc ++ engine up front, which would weigh upwards of 3 Kg

The impact on landing with such a heavy weight in front means Tricycle Gear (nose + main) is rarely used, and a Tail-Dragger is preferred

Why don't you tell us more about the proposed model? Or is this discussion purely academic?

piyushbadghare

Yes we are going for a tail dragger configuration. We are ready with the fabrication. Right no we are not using steering mechanism and keeping both the nose and tail gear as tandem. We are not using a nitro engine, rather we are using a motor.

sanjayrai55

Which motor/prop/battery configuration

And some more details about the airframe itself

I have attached the photo below. Now we have made the fuselage of carbon fiber. Can you guys help me by telling how to make the steerable tail gear( tail dragger config.). It will also be helpful if you guys can help our team financially as we have worked very hard and are falling short by a little amount:

This was our earlier tri wheel configuration. Now we have changed it to tail dragger configuration with steering

Deleted my response on seeing from your other thread that you are looking for underwriting, not undercarriage!
