I just swapped out my CF 10x4.7 slow fly props for CF 11x5 grappler style props.. I changed nothing weight wise and the hover shows about the same as before through my tlogs. Anybody have any ideas? My thought is the props maybe are more efficient..??

Here is the ecalc estimate of the new setup attached

  • That makes sense thank you! I guess I will buy some 11x4.7 slowflys

  • SloFly props create much more thrust because they have more surface area. You replaced them with a bigger prop that wasn't slo-fly, so you essentially took the surface area out of the width and added it to the length. The net result was break even it appears.
  • Setup is based off the 2013 3DR quad with 

    850kv motors

    AUW is ~1.4kg
