RE: Magnum .91 4-stroke users-what prop ?
Mine are on:
PT-60
Big Stik 60
Four Star 60
All of mine have Master Airscrew K series or Scimitar 14x6 props.
My brother has them on:
Hog Bipe
Super Sportster 60
Astro Hog
Something else (maybe?)
All of his have Master Airscrew K series or Scimitar, or APC, 14x6 props.
I currently run 10% fuel;, my brother runs 15%.
For the type of planes we have, and the way we like to fly, the 14x6 works really well. It seems to be a good combination of speed and thrust. Some of our engines turn a few hundred rpm more than the others so we're thinking of trying a 14x7 on them to add a little more load.
