Unfortunately some of my balsa made ones at miniscule weight are nowhere near to match PT Carbon Fiber ones from CZ, but recently started making my own composite Fiber Glass laminated to suit my Skeleton Giant, as I couldn't buy anything near to my requirement. The nearest one on market was APC14x4.7, still too heavy at 26grams so by slimming it down I have reduced weight to 22g.
Great performer, but my own design now the 2nd. one at 16x3.7 is much better, slower and more control responsive with a wider wash as my target.

Laminated prop in making.

Scratch built and modified wood props from heavy IC wood.

Test run of my 1st.one.

2nd.one at 16x3.7 much better.
