Take the Bridi recommended aileron and elevator rates and add 50% to them to start, then increase as needed. You won't break anything on this plane as rugged as it is (it is a Bridi design).

Aileron: Low Rate = 3/16" up/down
High Rate = 9/32" up/down to start, then increase to 3/8" up/down as desired (it'll handle as much as you can give it)

Elevator: Low Rate = 3/8" up/down
High Rate = 9/16" up/down to start, then increase to 3/4" up/down as desired (you can go more with a bolted wing option - if you reach the point where it wants to snap roll or stall a wing at full elevator throw, then back it off 1/8")

Rudder: Low Rate = 1/2" left/right
High Rate = all you can get

Just remember with the LA .46 it's not going to be a barn burner with unlimited vertical. It'll fly in the manner that planes 25 years ago where flown - on the wing, not the prop. It should have no problems getting off a grass field even it weight 6 lbs, and you'll learn the meaning of maintaining inertia and airspeed control.
