no, it isn't hard. all you will do is disconnedt the servo rods from the swashplate. Then turn them in or out depending on what you want the blades to do. You might not need to adjust them at all, just thought I might warn you. I would count how many turns you make for each control rod, and keep track of it. That way you can always set them back to where you were originally. If you ever have to replace a servo, you will need to now how to do this.
