New 60 Rigger test today. Not too bad for it second run. More tuning to follow. Thanks to John Knight for the sweet deal on this trick carbon fiber/wood kit. Enjoy!

I had both my scale and my F hydro out today. Both boats would take off about half way through the turns during hard rudder deflection. Then they would settle down in the straights. Temperate was about 88F with 80% humidity. Should I have selected a hotter plug? I was using odonnell blues...
