3S Lipo and Prop Question

[rcguy44]

I have read in a couple of places on this site about if you're running Lipos with everything else stock to change the prop to a GWS 10x6 HD. I'm running 11.1v 3S 1800 & 2200 Lipos in my cub and have been using the stock prop still but haven't been giving it full throttle for long periods of time. I was at my LHS today and they had a GWS 10x6 prop but it doesn't say HD on it anyplace and on the sales receipt it rang up as a GWSEP1060B prop. Will this prop work? What does the HD stand for? Heavy Duty? It does seem a little more flexible than the stock prop and defintely isn't as wide at the ends as the stock prop. Just wondering if I should try this prop or what?

Sounds right. If it's kind of skinny and straight sided-that's an HD Prop. The GWS SF/slow fly are elongated figure 8's with curvy blades.
