I used an incidence meter from Hangar 9 to set the throws before the maiden flight. It can measure throws to a tenth of a degree.



I fly with three flight modes - Precision, Spin Entry, and Roller. With the assistance of my local Team Futaba pilot, I set up the throws for these three flight modes prior to the maiden flight.

We set up this many degrees of elevator throw:

Precision: Up - 12.3, Down - 12.6
Spin Entry: Up - 14.7, Down - 14.9
Roller: Up - 23.0, Down 24.0

We set up the Precision and Spin Entry aileron throw at 24 degrees up and down with 100% ATV. The Roller throw is set at 60% ATV.

The aileron authority on the plane is incredible. I had to reduce the Precision (and Spin Entry) throw a couple times. I'm now at 85% ATV for Precision mode which is where the snap rolls are flown. If I do the math correctly it ended up with 20.4 degrees of aileron for snap rolls. My other planes always had 25 degrees of aileron for snaps.

The rudder throw was eye balled at what I was used to seeing. The throw for the Roller flight mode has 3 1/8" of throw (with 100% ATV) at the leading edge of the rudder at the bottom of the counterbalance. The Precision and Spin Entry flight mode are set for 55% ATV.
