Balancing X1 rotor blades
Modifying a Top Flight Precision Magnetic Balancer

I have cobbled together a magnetic prop balancer for my SYMA X1 rotor blades. I bought a Top Flight precision magnetic balancer and discovered that the balancer shaft was too large in diameter for the X1 rotor blades hub opening. I knew that a 1/16" drill bit works for a shaft so I started digging around in my RC junk yard for whatever parts I could use to make this unit work. I found that the old FM style antenna's end section was a little wider in diameter than 1/16" and would fit through the hub diameter opening of the X1 blades, and it was ferrous. I found that a SYMA S107G boom would slide over the antenna section and was not magnetic and that it would snug up inside the rotor blades recessed areas on both sides of the rotor hub.. Those Top Flight balancer cones actual fit very nicely over the tail boom. A little cutting and polishing and with some hypodermic needle rubber pistons for end stops I am good to go.  End stops could be of any material.
