What size servo arm for an Aerobeex Extra 330 20cc profile?

The title says it all… What size arm do I need to get full deflection on the Aerobeez Extra 330 20cc?

As a rule of thumb, to get "full deflection" on the AeroBeez 20cc profiles, you'll need an arm sufficiently long to reach the ground at the time the front falls off… i.e.: if the front falls off at 6' altitude, you'll need a 6' arm to reach both pieces…

You'll have more value in servos than what the plane is worth - use the cheap diamond servos as it is a cheap plane

I have built one from peak models, not sure if it is the same but i think so. While it flexes a bit under hard idle shake, i dont think it is a bad plane.

I used savox servos, because i want a plane that flys well. I wanted a 20cc profile arf, and the choice is limited!

The savox comes with nice arms, i used the large ones, i believe they are 1,5 inches. There is an excellent build thread at RC thrasher, was just about to post you the link but ive seen that the site is down.
