OK, I'm back from the fly field and I have to say I'm making progress. First, I have to say that setup is tantamount. I can't see how you's guys can reach out and touch your plane in a hover all the while give constant input. Maybe one sticks worth of constant input... Still, the plane has to have the ability to 'camp out'. That said, I checked my setup. I did put some right thrust on my engine when I built it. The washers had squashed into the mounts and squelched all the angle. I slipped some larger diameter washers in and reestablished the offset. Next, I eased my expo on the radio. I backed off the expo from -80 to -60 all the way around. I have no low rates Futaba 8U. Finally, I moved my battery as far aft as I could go and removed some lead ballast from the tail. WOW, biggest difference. I'm closer but still not there. I think my next move is a 14x4W on the S72. The 13x6 has too much jump for my inputs. No LHS handy to buy a prop so I have that excuse to ride. Oh. The cooler air this evening made a difference too. I'm burning the fuel so bare with me.....
