For my first flights, I set up my throws so that at HIGH rates I'm using the recommended throws in the manual.

For low rates I'll use 50 to 60% of that.

In a corresponding manner I set up the Expo for HIGH rates to be 50% and 20 to 30% on low for ailerons and elevator.

Rudder you want lower so I have it at 35% Expo for high rates and 15 - 20% expo on low rates.

The idea is to keep the plane easily flyable for it's maiden flight...


Then I fly the plane and see how it goes.

If it's two responsive I can bring it in on low rates.

If I find it too sluggish I'll dial up the throws so that the surfaces move beyond the recommended for high rates, but within or less than the recommended for low rates ( remembering to leave in enough elevator for landings ).

I leave the Expo the same, and just adjust the throws.
