Due to the usual string of code bugs and dumb thumbs, I've dinged my ArduCopter up a good bit in the testing phase. You can get a good crash repair kit from FahPah that has the most commonly-broken parts, or you can make your own. Thanks to Sandro Benigno, at least some of them (the easy-to-crack dome headers) are now very easy: just have them laser cut at Ponoko.

Just click here and add it to your personal factory. Then when you go to have it made, select the following (you'll get four pairs, which is all you'll need for life!):

Acrylic - Clear

3.0 mm
P1 - 181.0 mm long x 181.0 mm wide
Making: $15.10
Material: $2.00
Total: $17.10 <--- (4 pairs + 1 upper)
Here's my stack, which just arrived. They fit great!

And next generation ArduCopter Quad / Hexa frame center parts will look like this too. We are still looking and testing different materials and cut options but it looks like that future parts will be made from polycarbonate even tho it will be harder to manufacture them.

My arducopter hit a tree and fell about 20 feet. And the week point that broke was the long spacers that keeps those plates stacked together. We might want to improve like have metal instead? It wouldn't add too much weight. But then again, it would probably break or crack the plates

Taylor, if you were able to break those 25mm nylon spacer.... I'm happy to send some spares to you. Even I have not been able to break them and I have been even jumping on top of my quads.

@Jani. It didn't break at the very thick part. They broke where the threaded bolt part connects to the spacer.

@Chris, great that it fits well on your Arducopter too!
@Jani, I loved the hexa ones. They look like flame rings.

Here goes my laser cutted ones working:

Awesome.  Mine has broken countless times.

 

Looking forward to this.  The $17 doesn't cover shipping.  It was $9 to the southern US.  We'll see how it works out!

I have had nothing but problems with acrylic parts cracking on things I've designed. It might be worth trying wood or ABS.

working with acrylic needs specially designed cutting tools and rather high speed. Another good material is polycarbonate tho it's a bit difficult material to work if you want to have nice surface.

hi need a quadcopter carry more payload which motors and battery do u suggest

If you want to make it even cheaper you could see if there is a fablab nearby. They usually have lasercutters (check if there is a local fablab near you). It's more fun to do it your self:)
