Flybar Weights Assembly
If you need to reassemble (or remove) the flybar weights,
please observe the following:
1. Align the flybar block as shown in Fig. 4-1.
2. Slide the plastic block sleeve over the hook at the end of
the flybar through the opening 1 shown in Fig. 4-1 till the
hook is on the outside of the sleeve as shown in Fig 4-2 .
3. Line up the notch and the lug (Fig.4-4), and slide the
plastic sleeve over the block so the block is completely
inside the sleeve.
4. Twist the sleeve with the block inside 90
wise relative to the opening the end hook was inserted in,
and gently position the hook in that slot (see Fig. 4-3).
5. Make sure that the sleeve and the block are in the correct
position because if they come off during flight the speed and
the weight of the block can cause injury.
6. To remove the weights just follow the procedure in
reverse order.
