Great prop on my Perfections.
Performance with a schambeck 1025 is more than sufficient and a much nicer fit on the fuse than the rf 16x8,5 small!

Very prompt delivery, as usual from Hyperflight. I normally use aeronaut blades, so, at more than 3 times the cost, I was pleased to find a considerable improvement in performance from these blades, though obviously not a 3 fold improvement !
A good performance upgrade.

it's hard to review prop blades in the middle of
Dec.. They look great, fit well, and fit the Maxa
well. Running them in the shop is not a fare
test, but in the pacific NW it is what it is.
They arrived shortly after I ordered them, great

Simply the best.

Fabulous. Half the mass of equivalents, with better performance, and the neatest tuck along the fuselage in most models. Drag is much reduced, my Supra is virtually silent on glide.
I am disappointed that they do not suit my Kappa, but that is because of the peculiar shape of the plane at the nose of the fuselage. Perfect on my other models, though.
And they look cool!

Used with the Powerline 1025 motor, instead of pulling 45 amps as expected using these blades the motor is only pulling 35 amp. mounted in a Kappa 35 at 1400 grams flying weight it climbs to 150 metres in 15 seconds.

This prop is a great product. The profile is very slim and it sure aids minimizing parasite drag on your glider.
It is also about half the weight of other similar size props!
I was expecting to get higher amperage out of this prop so perhaps it is a good idea to buy one with a coarser pitch that the one you are already using.
Overall, very satisfied!
