mr. scale; I don't think any prop is going to fix the 4lb difference between your Stinger and waynem's. Maybe a 50cc something?..............
I'd have to agree with John. Your up near the Giant Stinger range weight wise. Any way to put it on a Diet and loose a few pounds?
If you can't lighten the airframe any then think of ditching the Wheelpants and look into CF landing gear and Lithium batteries.
