Next, turn the pushrods from the servos, in or out to get the swashplate so that it is EXACTLY 1/2" from the top of the main shaft as shown in the picture. Try to keep the swashplate as level as possible.

Next, turn the pushrods from the servos, in or out to get the swashplate EXACTLY level. You can use a small leveling bubble for this. The easiest way I've found to do this is by using a drafting triangle. Place the edge of the triangle on the rotor shaft and align the swashplate with the bottom edge.

It is important for the swashplate to be level not only from the side of the helicopter, but also from the front and rear of the helicopter.

Remember to maintain the 1/2" distance from the top of the shaft while leveling the swashplate.

The better, and more precise you get this step, the better the heli will fly.
