Mr. Hester,
If you get the chance, borrow an Engel carbon 18x11 prop to try on the YS 160---they really like each other,it sounds good on the YS(bit harsh on 2 strokes though), and it's half the weight of the APCs.
Not that you'd need it, but you could take the lead off again.....
Not sure where to even get Engel props in the US.....
The weight works out to 3:1. 3 ounces on the nose equals one in the tail. I added 6 ounces to the nose by the time I was done, balanced it and it needed 2 in the tail. Total of 8 ounces, so my plane now weighs slightly less than 10 lbs.
So again I stress if you're building this plane and you plan on using the YS160 (or something of equal weight) move the wing tube forward 1/4"-3/8". Or, you could simply run a 2 servo in the stab elevator set up and it would wash.
Also as a fairly critical note, after a lot of testing, I suggest the CG location on the leading edge of the wing tube for a starting CG!!!! I'm adding that to the plans and instructions, but it's not all that big of a deal, it doesn't fly that much different. That CG range is fairly big, just shoot for the LE of the wing tube or slightly behind it.
