Flight Log: 9-11-16.

Four flights with the Forza with new Switch main Blades.  Seems to work well.  Honestly cannot tell difference.  Did not help so much with strange thunder noise chopper made when adding positive pitch when inverted.  Upon closer inspection discovered main shaft had about two mm of up and down play.  Tightened collar at home which eliminated play.

Did a few shaky piro flips.  Sigh.

Dad flew well.  More and more inverted and getting closer to the ground.

Got to field at 780 am and left by 910 am.  Super fast.
