APC-E 21x14 vs. Pt Model 21x14 Carbon
I wanted to know which of theese props is better. Let´s suppose that cost is not an issue and both have the same price, which is more eficient, quieter, lighter. The PT is stiffer, is that an advantage ?
Which one would you choose?
Thanks.
Ricardo.

The APC is more quiet and more efficient, the PT is lighter and stiffer. Tried both and liked the APC more

At least the PT prop I have has thicker tips and a more blunt trailing edge. I could notice sound and performance differences with the APC.

The APC design is extremely efficient, so deviating from this design (airfoil, planform, TE thickness, etc) is not likely to increase efficiency. IF all other things are equal, lighter and stiffer is better for performance, with the possible exception of noise - some hollow CF props resonanate (like a drum) and are louder than an APC.

Hello Hans,
I’ve recently, since a few months now live in The Netherlands. In the Hague to be specific.
I’ve done this to continue with my studies at de Haagse Hogeschool in Delft.
And was wondering where do you guys fly.
It may be possible for me to bring my plane from home, Aruba.
Miss flying at times, but at the same time I don’t have as much time as I would like.
Though I’m really thinking to bring my Leviosa so I could fly and keep learning. Hah.
