I have one on my 36% Katana, DA 100. Of all the props I tried it is by far the best for 3D. Its fairly light too, ounces lighter than a mejzlik. If you want just 3D, its the prop for you. It does OK for IMAC, but menz is a better compromise of both. Would I buy another? In a heartbeat for a 3D plane. Loaned it to a friend with a sukhoi and he liked it better than a menz, 3w, etc.
