I am about to launch a H9 Pizazz which I hope to learn how to 3D, do fast servos help in controlling, if so do you need these servos on all flght surfaces?

Any other setup tips are appreciated

I have standard futaba 148's on the ailerons a hitec 605 on the rudder pull-pull and two hitec hs-85mg's on the elevator. I put the elevator servos in the tail and with a saito 65 still had to add 2 oz of lead in the tail. I will try 605's on the elevator so I can get more throw and get rid of the lead.

The plane fly's great with the 65 swinging the 14-4 wide blade on 35%. Hovers are gettin lower and better with practice and the bird is rock solid in all phases of flight.

my favs on small planes has to be the hitec 425 BB servos on a 6v batt pack. servos run about $14ea and are very smooth and fairly fast on 6v
