RC plane balancer

This is a remix of an RC plane balancer made by HampOp. I found his version too small so I made a new one based on his design.

###What to print :
- base * 2
- hinge * 2
- pad * 4
- rulerLeft * 1
- ruler Left * 1
- rulerStop * 2

###What you need :
- 6 M3 * 14 screw
- 6 M3 nuts
- 2 M4 * 14 screw
- 4 M4 * 18 screw
- 6 M4 self-locking nuts
- 10mm tubing (you can use bigger tube and drill bigger hole but be aware of not breaking the piece)

###Assembly instructions :
- Screw the ruler on the base with M3 * 14 screw and M3 nuts, rotate it by 180 degrees if you want to use metric or imperial.
- Screw the hinge on the base with M4 * 14 screw and M4 self-locking nut, do not tight the plastic pieces. This part must be free of movement, using self-locking nut will prevent unscrewing.
- Screw the pad on the hinge with M4 * 18 screw and M4 self-locking nut, do not tight the plastic pieces. This part must be free of movement, using self-locking nut will prevent unscrewing.
