Default What size servo arms for IMAC

I'm converting my 50cc plane from 3D throws in order to compete in IMAC. I would like some guidance on what length aileron and elevator servo arms length to use. Currently my aileron servo arms are 1.25" and elevators 1.5". This gives 3D style control throws.

I would like to set up for throws more like:
Elevator = 12 degrees
Ailerons = 20 degrees

The horns on the surfaces are not adjustable in height so my changes will need to be the servro arms.

My guess was about 1" arms. I appreciate everyones thoughts.

Thank you.

1" MPI arms with 4-40 ball links. Around $8 each. That will give much better mechanical advantage. Depending on the servos used you should  notice the difference.
