Prop is good.

17 to 18 was about average for the version 1 Edge, so you did well. No worries, they flew great at 20 lbs!! The first one I did I threw everything into it and added wood everywhere, wrongly thinking it needed more strength. It just ended up heavier, not stronger The next two got much better

The new ones (v-II) can come in between 15.5 and 17.5, depending on what's used.

You're one of the few that remembers my earlier screen name. Thank you

Remind RTK that he needs to get out to the fields more often if he's going to flip anything. The poor boy's prop arm must be starting to atrophy and may have reached the point where he can't even flip me the bird anymore, lol.
