Well I ran my 14X11 4 blade prop yesterday. It pulled good , was very quiet but didn't seem to allow the 110 to turn up to potential. Tommy , your 13.8X10 may be better than I 1st thought.

I too am running the Bolly F3A large gear. Worth the upgrade -no prop clearance issues.

I contacted Dubro directly attempting to purchase the control takeoffs. I was first told they would only sell them in lots of #50. when I said "OK then how much would 50 cost?" they then said no go they don't break the packages. That's funny as I see them selling many other parts individually. Maybe we can all get together and bug them until they cave & sell us a case - we could then share with everyone
