Looks fine, but at 73g it is almost twice the weight of a Falcon v2 (37g).

Yes, weight is much better than APC, and the difference is a bit more than that. I did some comparisons and the similarly sized APC's weigh more than 130g, if I recall correctly. So to go from APC to Falcon v2 is about 100g (more than 4 ounces) - huge difference in rotating mass! But it is interesting how often the CF versions copy the APC shape. It will be interesting to see what APC does in the way of CF propeller development.

Yes, it look like most of the carbon fibre propellers are copies of the APC shape. So I agree With you that it will be interesting to see what APC will do to develop a lighter propeller.

I tried them on my 40 Cap 232 and both 32-10's split accross the hub and broke 4 of my hub bolts (when they first came out in 2003). They didn't pull very well either, compared to a Menz or my Air Models 32-11. I'm sure they are much better now, but I will never run them again. Not downing the product, just sharing my experience with them.


Best of luck,

Bill

Look at Axi propellers and compare them to Bielas
