I recently bought a 26x10 prop from Roger at Aerografixs, and now that I have flown it want to add my .02 cents worth. The prop is on a zdz 80 and I can't believe the difference between it and the zinger I had on before.(pro 24x10) Now before every one gets excited, I know the zinger was a little small and it was a little less money, but the difference is staggering! I paid 55 Canadian for the Forgues and think it is worth every penny. The prop came drilled for my engine and the balance amounted to about six swips with some 320 to get it right on. Roger tells me the prop is a clone of the Menz and he built a copying machine to manufacture them. With the price of the big props these days, I think I got a real bargain. I am in no way affiliated with Roger or Aerografixs, just a very happy customer. We live on opposite sides of the country.
