Basically its a coordinated turn.

Add Aileron, little elevator, add rudder to complete the turn.

Too much elevator and the heli will stop.
Too much aileron and not enough elevator and the heli will slide sideways .. hopefully you have enough altitude...

Rudder helps finish off..

The more Aileron the more elevator to bring it around...

if you don't have a HH gyro the tail will follow throw depending on the sensitivity of the gyro you might need a little rudder..

Dunno what a "proper" turn is.. as long as it turns and stays in the air I would call it a "proper" turn..
